74ALVCH162245
Rev. 3 — 16 January 2018
16-bit bus transceiver with direction pin and
30 Ω termination resistor; 3-state
Product data sheet

General description
The 74ALVCH162245 is a 16-bit transceiver featuring non-inverting 3-state bus
compatible outputs in both send and receive directions.
The 74ALVCH162245 features two output enable (nOE) inputs for easy cascading and
two send/receive (nDIR) inputs for direction control. nOE controls the outputs so that the
buses are effectively isolated. This device can be used as two 8-bit transceivers or one
16-bit transceiver.
The 74ALVCH162245 is designed with 30 Ω series resistors in both HIGH and LOW
output states.
The 74ALVCH162245 has active bus hold circuitry which is provided to hold unused or
floating data inputs at a valid logic level. This feature eliminates the need for external
pull-up or pull-down resistors.
