ST3222E Datasheet Rs-232 Drivers/receivers

Manufacturer: STMicroelectronics

Overview: ST3222EB ST3222EC ± 15 kV ESD protected, 3 to 5.5 V low power, up to 250 Kbps, RS-232 drivers and.

General Description

The ST3222E is a 3 V powered EIA/TIA-232 and V.28/V.24 communications interface with low power requirements, high data-rate capabilities and enhanced electrostatic discharge (ESD) protection to ± 8 kV using IEC1000-4-2 Contact Discharge and ±15 kV using the Human Body Model.

ST3222E has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 5 V supplies with a dual charge pump.

The charge pump requires only four small 0.1 mF external capacitors for operation form 3 V supply.
