DESCRIPTION
The 74ABT2953 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT2953 device is an 8-bit registered inverting transceiver.
Two 8-bit back-to-back 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 (CPXX) provided
that the Clock Enable (CEXX) is Low. The data is then present at
the 3-State output buffers, but is only accessible when the Output
Enable (OEXX) is Low. Data flow from A inputs to B outputs is the
same as for B inputs to A outputs.
