ST207EB

ST207EC

± 15 kV ESD protected 5 V RS-232 transceiver

Features

■ ESD protection for RS-232 i/o pins: ±15 kV

human body model

■ 230kbps data rate

■ Guaranteed slew rate 3 V/ms (min.)

■ Operates from a single 5 V power supply

■ Packaged in SSO-24 and TSSOP24

Description

The ST207E is a 5 driver and 3 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

and receivers of the ST207E meet all EIA/TIA-

232E and CCITT V.28 specifications at data rates

up to 120 Kbps, when loaded in accordance with

the EIA/TIA-232E specification.

The ST207E operates with four 0.1 µF capacitors.

It came in 24-pin SSOP and TSSOP packages.
