description
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 VCC, and V is raised toward GND. Receiver outputs also can be placed in the high-impedance state by setting EN high. The SN65C3222 is characterized for operation from 40°C to 85°C. The SN75C3222 is characterized for operation from 0°C to 70°C.

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. The package thermal impedance is calculated in accordance with JESD 51-7.
