DESCRIPTION
The 74ALVC16245(74ALVCH16245) is a 16-bit transceiver featuring
non-inverting 3-State bus compatible outputs in both send and
receive directions.
The 74ALVC16245(74ALVCH16245) 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 74ALVCH16245 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.
The 74ALVC16245 has 5V tolerant inputs.
