1 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.

2 Features and benefits
