LTC1344AIG#PBF

LTC1344A 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 device forms a complete software-selectable multiprotocol serial port. A data bus latch feature allows sharing of the select lines between multiple interface ports. software-selectable cable termination for: RS232 (V.28), RS423 (V.10), RS422 (V.11), RS485, RS449, EIA530, EIA530-A, V.35, V.36, X.21. It is used in applications such as data networking, CSU and DSU, data routers.
