ST202EB, ST202EC

ST232EB, ST232EC

±15 kV ESD-protected 5 V RS-232 transceiver

Datasheet - production data

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 ST202EB, ST202EC, ST232EB, and

ST232EC are two-driver, two-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 ST202EB, ST202EC,

ST232EB, and ST232EC use a single 5 V supply

voltage.

The ST232EB and ST232EC operate with four

1 µF capacitors, while the ST202EB and

ST202EC operate with four 0.1 µF capacitors,

further reducing cost and board space.
