LTC1344 - Software SelectableCable Terminator

The LTC®1344 features six software-selectable multiprotocol cable terminators. Each terminator can be configured as an RS422 (V.11) 100Ohms 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. The LTC1344 is available in a 24-lead SSOP.
