DS14185
EIA/TIA-232 3 Driver x 5 Receiver
General Description
The DS14185 is a three driver, five receiver device which
conforms to the EIA/TIA-232-E standard.
The flow-through pinout facilitates simple non-crossover
board layout. The DS14185 provides a one-chip solution for
the common 9-pin serial RS-232 interface between data ter-
minal and data communications equipment.
Features
n Replaces one 1488 and two 1489s
n Conforms to EIA/TIA-232-E
n 3 drivers and 5 receivers
n Flow through pinout
n Failsafe receiver outputs
n 20-pin SOIC package
