DESCRIPTION
The 74ABT16952 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16952 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.
