■ ESD PROTECTION FOR RS-232 I/O PINS:
± 15KV HUMAN BODY MODEL
■ GUARANTEED 230kbps DATE RATE
■ GUARANTEED SLEW RATE RANGE 3 to
30V/µs
■ OPERATE FROM A SINGLE 5V 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
± 15KV electrostatic discharge (ESD)
shocks. The drivers meet all EIA/TIA-232E and
CCITT V.28 specifications at data rates up to
230Kbps, when loaded in accordance with the
EIA/TIA-232E specification. The ST202E/232E
use a single 5V supply voltage.
The ST232E operates with four 1µF capacitors,
while the ST202E operates with four 0.1µF
capacitors, further reducing cost and board space.
