3 Driver x 5 Receiver
Features
n n n n n n n Replaces one 1488 and two 1489s Conforms to EIA/TIA-232-E 3 drivers and 5 receivers Flow through pinout Failsafe receiver outputs 20-pin SOIC package LapLink ® compatible −200 kbps data rate
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 terminal and data communications equipment.
