description/ordering information
The SN65C3222 and SN75C3222 consist of two line drivers, two line receivers, and a dual charge-pump circuit
with 15-kV ESD protection pin to pin (serial-port connection pins, including GND). The 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. The devices
operate at data signaling rates up to 1 Mbit/s and a driver output slew rate of 24 V/µs to 150 V/µs.
The SN65C3222 and SN75C3222 can be placed in the power-down mode by setting PWRDOWN low, which
draws only 1 µA from the power supply. When the devices are powered down, the receivers remain active while
the drivers are placed in the high-impedance state. Also, during power down, the onboard charge pump is
disabled, V+ is lowered to V , and V− is raised toward GND. Receiver outputs also can be placed in the
CC
high-impedance state by setting EN high.

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
