LTC1344A - Software-Selectable Cable Terminator
The LTC®1344A 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 LTC1543 and LTC1544, the LTC1344A forms a complete software-selectable multiprotocol serial port. A data bus latch feature allows sharing of the select lines between multiple interface ports.
The LTC1344A is similar to the LTC1344 except for a difference in the Mode Selection table.
The LTC1344A is available in a 24-lead SSOP.
