Кабель64,75 В ~ 5,25 В-40°C ~ 85°C

Overview

The LTC1344A features six software-selectable multiprotocol cable terminators. Each terminator can be configured as an RS422(V.11)100Q minimum differen- tial 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 buslatch feature allows sharing of the select lines between multiple interface ports. The LTC1344A is similar to the LTC1344AIG except for a difference in the Mode Selection table. The LTC1344A is available in a 24-lead SSOP.
