LTC1344IG#PBF

LTC1344IG#PBF is a software-selectable cable terminator. It features six software-selectable multiprotocol cable terminators. Each terminator can be configured as an RS422 (V.11) 100 ohm minimum differential load, V.35 T-network load or an open circuit for use with RS232 (V.28) or RS423 (V.10) transceivers that provide their own termination. When combined with the LTC1343, the LTC1344 forms a complete software-selectable multiprotocol serial port. A data bus latch feature allows sharing of the select lines between multiple interface ports.
