Description

The 74ALVT16953 is a high-performance BiCMOS product designed for V_CC operation at 2.5V or 3.3V with I/O compatibility up 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.
