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
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.
