Outputs
General Description
The ABT16374 contains sixteen non-inverting D flip-flops
with TRI-STATE outputs and is intended for bus oriented
applications. The device is byte controlled. A buffered clock
(CP) and Output Enable (OE) are common to each byte and
can be shorted together for full 16-bit operation.
