STMicroelectronics 

ST202B

ST202C

5 V powered multi-channel RS-232 drivers and receivers

Features

■ Supply voltage range: 4.5 to 5.5 V

■ Supply current no load (typ.): 1.5 mA

■ Transmitter output voltage swing (Typ): ± 9 V

■ Transition slew rate (typ.): 12 V/ms

■ Receiver propagation delay (typ.): 0.1 ms

■ Compatible with MAX202

■ Receiver input voltage range: ± 30 V

■ Data rate (typ.): 400 kbps/s

Description

The ST202 is a 2 driver, 2 receiver device

following EIA/TIA-232 and V.28 communication

standard. It is particularly suitable for applications

where ± 12 V is not available. The ST202 uses a

single 5 V power supply and only four external

capacitors (0.1 µF). Typical application are in:

portable computers, low power modems,

interfaces translation, battery powered RS-232

networks.
