DESCRIPTION
The 74ALVT16952 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 74ALVT16952 is a dual octal registered 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.
