ST202EBTR

± 15 kV ESD protected 5 V RS-232 transceiver

STMicroelectronics 

ST202EB - ST202EC

ST232EB - ST232EC

± 15 kV ESD protected 5 V RS-232 transceiver

Features

■ ESD protection for RS-232 I/O pins:

■ ± 15 kV human body model

■ Guaranteed 230 kbps date rate

■ Guaranteed slew rate range 3 to 30 V/ms

■ Operate from a single 5 V power supply

Description

The ST202E/ST232E are a 2 driver 2 receiver

devices designed for RS-232 and V.28

communications in harsh environments. Each

transmitter output and receiver input is protected

against ± 15 kV electrostatic discharge (ESD)

shocks. The drivers meet all EIA/TIA-232E and

CCITT V.28 specifications at data rates up to 230

kbps, when loaded in accordance with the

EIA/TIA-232E specification. The ST202E/232E

use a single 5 V supply voltage.

The ST232E operates with four 1 µF capacitors,

while the ST202E operates with four 0.1 µF

capacitors, further reducing cost and board

space.
