SP2209E DS/06
SP2209E High ESD Dual Port RS-232 Transceivers
Copyright 2000 Sipex Corporation
DESCRIPTION
The rugged, high ESD SP2209E device is a complete dual RS-232 port integrated onto a
single integrated circuit. Six drivers and ten receivers provide designers a dual port solution
fully meeting the EIA/TIA-232 and ITU-T V.28/V.24 communication protocols and can be
implemented in applications such as personal desktop computers and workstations.
Features include high transmission rates, low power consumption, an internal charge-pump
power supply that requires only two capacitors, space saving 38-pin TSSOP package
dimensions, and compatibility with the EU directive on electromagnetic compatibility.
This device is ideal for operation in electrically harsh environments or where RS-232 cables
are frequently being plugged and unplugged. This device is also immune to high RF field
strengths without special shielding precautions.
