description/ordering information
The SN65C3243 and SN75C3243 consist of three line drivers, five line receivers, and a dual charge-pump
circuit with 15-kV ESD protection pin-to-pin (serial-port connection pins, including GND). These devices
provide the electrical interface between an asynchronous communication controller and the serial-port
connector. The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V
supply. In addition, these devices include an always-active noninverting output (ROUT2B), which allows
applications using the ring indicator to transmit data while the devices are powered down. The devices operate
at data signaling rates up to 1 Mbit/s and an increased slew-rate range of 24 V/µs to 150 V/µs.

description/ordering information (continued)
Flexible control options for power management are available when the serial port is inactive. The
auto-powerdown feature functions when FORCEON is low and FORCEOFF is high. During this mode of
operation, if the devices do not sense a valid RS-232 signal, the driver outputs are disabled. If FORCEOFF is
set low, both drivers and receivers (except ROUT2B) are shut off, and the supply current is reduced to 1 µA.
Disconnecting the serial port or turning off the peripheral drivers causes the auto-powerdown condition to occur.
Auto-powerdown can be disabled when FORCEON and FORCEOFF are high and should be done when driving
a serial mouse. With auto-powerdown enabled, the device is activated automatically when a valid signal is
applied to any receiver input. The INVALID output is used to notify the user if an RS-232 signal is present at any
receiver input. INVALID is high (valid data) if any receiver input voltage is greater than 2.7 V or less than −2.7 V
or has been between −0.3 V and 0.3 V for less than 30 µs. INVALID is low (invalid data) if all receiver input
voltages are between −0.3 V and 0.3 V for more than 30 µs. Refer to Figure 5 for receiver input levels.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltages are with respect to network GND.
2. Maximum power dissipation is a function of T (max), θ , and T . The maximum allowable power dissipation at any allowable
