The Intersil ICL32X7 devices are 3.0V to 5.5V powered
RS-232 transmitters (five)/receivers (three) which meet
Features
• Pb-Free Plus Anneal Available (RoHS Compliant)
(see Ordering Information)
ElA/TIA-232 and V.28/V.24 specifications, even at
= 3.0V. Targeted applications are ISDN Terminal
V
CC
• 15kV ESD Protected (Human Body Model)
Adaptors, PDAs, Palmtops, peripherals, and notebook and
laptop computers where the low operational, and even lower
standby, power consumption is critical. The ICL3217’s
efficient on-chip charge pumps, coupled with an automatic
powerdown function, reduces the standby supply current to
a 1A trickle. Small footprint packaging, and the use of
small, low value capacitors ensure board space savings as
well. Data rates greater than 250kbps are guaranteed at
worst case load conditions. This family is fully compatible
with 3.3V only systems, mixed 3.3V and 5.0V systems, and
5.0V only systems, and is a lower power, pin-for-pin
replacement for ‘207 and ‘237 type devices.
• 5V Lower Power Replacement for MAX207, HIN207,
HIN237
• Meets EIA/TIA-232 and V.28/V.24 Specifications at 3V
• Latch-Up Free
• On-Chip Voltage Converters Require Only Four External
0.1F Capacitors
• Automatic Powerdown (I

= 1A, ICL3217 Only)
• Receiver Hysteresis For Improved Noise Immunity
• Guaranteed Minimum Data Rate . . . . . . . . . . . . . 250kbps
• Guaranteed Minimum Slew Rate . . . . . . . . . . . . . . . 6V/s
• Wide Power Supply Range . . . . . . . Single +3V to +5.5V
The ICL3217 features an automatic powerdown function
which powers down the on-chip power-supply and driver
circuits. This occurs when an attached peripheral device is
shut off or the RS-232 cable is removed, conserving system
power automatically, without changes to the hardware or
operating system. The ICL3217 powers up again when a
valid RS-232 voltage is applied to any receiver input.
Applications
• Any System Requiring RS-232 Communication Ports
- Battery Powered, Hand-Held, and Portable Equipment
- Laptop Computers, Notebooks, Palmtops
- Modems, Printers and other Peripherals
- ISDN Terminal Adaptors and Set Top Boxes
Table 1 summarizes the features of the devices represented

Transmitters
Detailed Description
The transmitters are proprietary, low dropout, inverting drivers
that translate TTL/CMOS inputs to EIA/TIA-232 output levels.
Coupled with the on-chip 5.5V supplies, these transmitters
deliver true RS-232 levels over a wide range of single supply
system voltages.
The ICL32X7 interface ICs operate from a single +3V to +5.5V
power supply, guarantee a 250kbps minimum data rate,
require only four small external 0.1F capacitors, feature low
power consumption, and meet all ElA RS-232C and V.28
specifications. The circuit is divided into three sections: The
charge pump, the transmitters, and the receivers.
ICL3217 transmitter outputs disable and assume a high
impedance state when the device enters the automatic
powerdown mode. These outputs may be driven to 12V when
disabled.
Charge-Pump
Intersil’s new ICL32XX family utilizes regulated on-chip dual
charge pumps as voltage doublers, and voltage inverters to
generate 5.5V transmitter supplies from a V
supply as low
Both devices guarantee a 250kbps data rate for full load

as 3.0V. This allows these devices to maintain RS-232
compliant output levels over the 10% tolerance range of 3.3V
powered systems. The efficient on-chip power supplies require
only four small, external 0.1F capacitors for the voltage
conditions (3k and 1000pF), V

Receivers on the ICL3207 are always active. The ICL3217
receivers disable when in the automatic powerdown state,
thereby eliminating the possible current path through a

Even greater power savings is available by using the ICL3217
which features an automatic powerdown function. When no
valid RS-232 voltages (see Figure 4) are sensed on any
receiver input for 30s, the ICL3217 automatically enters its
powerdown state (see Figure 5). In powerdown, supply current
drops to 1A, because the on-chip charge pump turns off (V+

transmitter outputs three-state (see Table 2). This micro-power
mode makes the ICL3217 ideal for battery powered and
portable applications. Invalid receiver levels occur whenever
the driving peripheral’s outputs are shut off (powered down) or
when the RS-232 interface cable is disconnected. The
ICL3217 powers back up whenever it detects a valid RS-232
voltage level on any receiver input (such as when the RS-232
cable is reconnected). The time to recover from automatic
powerdown mode is typically 100s.

When using minimum required capacitor values, make sure
that capacitor values do not degrade excessively with

of ripple on V+ and V-.

two transmitter outputs properly go to opposite RS-232 levels,
with no glitching, ringing, nor undesirable transients. Each
transmitter is loaded with 3kin parallel with 2500pF. Note
that the transmitters enable only when the magnitude of the
supplies exceed approximately 3V.
This automatic powerdown feature provides additional system
power savings without changes to the existing operating
system or hardware.
Utilizing power management circuitry, to power down the rest
of the communication circuitry (e.g., the UART) when the
ICL3217 powers down, produces even greater power savings.
Connecting a transition detector to the V- pin (see Figure 3) is
an easy way for the power management logic to determine
when the ICL3217 enters and exits powerdown.

Capacitor Selection
The charge pumps require 0.1F, or greater, capacitors for
3.3V operation. With 0.1F capacitors, five percent tolerance
supplies (e.g., 3.14V minimum) deliver greater than 5V
transmitter swings at full data rate, while ten percent tolerance
supplies (e.g., 2.97V minimum) deliver 4.95V transmitter
swings. If greater than 5V transmitter swings are required with
a ten percent tolerance 3.3V supply, 0.22F capacitors are
recommended (see Table 3). Existing 5V applications typically
utilize either 0.1F or 1F capacitors, and the ICL32X7E works
well with either value. New 5V designs should use 0.22F
capacitors for the best results. For other supply voltages refer
to Table 3 for capacitor values. Do not use values smaller than
those listed in Table 3. Increasing the capacitor values (by a

The ICL32XX maintain the RS-232 5V minimum transmitter
output voltages even at high data rates. Figure 7 details a
transmitter loopback test circuit, and Figure 8 illustrates the
loopback test result at 120kbps. For this test, all transmitters
were simultaneously driving RS-232 loads in parallel with
1000pF, at 120kbps. Figure 9 shows the loopback results for a
single transmitter driving 1000pF and an RS-232 load at
250kbps. The static transmitters were also loaded with an RS-
232 receiver.
