DESCRIPTION

The 74ALVT16953 is a high-performance BiCMOS product

to 5V.

The 74ALVT16953 is a dual octal registered inverting transceiver.

Two 8-bit registers store data flowing in both directions between two

bidirectional buses. Data applied to the inputs is entered and stored

on the rising edge of the Clock (nCPXX) provided that the Clock

Enable (nCEXX) is Low. The data is then present at the 3-State

output buffers, but is only accessible when the Output Enable

(nOEXX) is Low. Data flow from A inputs to B outputs is the same as

for B inputs to A outputs.

Active bus hold circuitry is provided to hold unused or floating data

inputs at a valid logic level.
