DSV14196
+3.3V Supply EIA/TIA-232 5 Driver x 3 Receiver
General Description
The DSV14196/DSV14196T is a five driver, three receiver
device which conforms to the EIA/TIA-232-E and the ITU-T
V.28 standards.
The flow-through pinout facilitates simple non-crossover
board layout. The DSV14196/DSV14196T provides a peripheral side one-chip solution for the common 9-pin serial
RS-232 interface between data terminals and data communications equipment.
Features
n Conforms to EIA/TIA-232-E and ITU-T V.28
n 5 drivers and 3 receivers
n Flow-through pinout
n Failsafe receiver outputs high when inputs open
n 20-pin wide SOIC package
n LapLink
®
compatible—230.4 kbps data rate
n +3.3V Logic Interface
