DESCRIPTION
The ST202E/ST232E are a 2 driver 2 receiver
devices designed for RS-232 and V.28
communications in harsh enviroments. Each
transmitter output and receiver input is protected
against ± 15KV electrostatic discharge (ESD)
shocks. The drivers meet all EIA/TIA-232E and
CCITT V.28 specifications at data rates up to
120Kbps, when loaded in accordance with the
EIA/TIA-232Especification.
The ST202E/232E use a single 5V supply
voltage.
The ST232E operates with four 1µF capacitors,
