description
The ’AC16822 and ’ACT16822 are inverting 20-bit
D-type flip-flops composed of two 10-bit sections
with separate control signals. For either 10-bit
flip-flop section, the inverse of the data present at
the corresponding D inputs is stored in the
flip-flops on the rising edge of the clock input
(1CLK or 2CLK) and appears on the appropriate
Q outputs if the output enable 1OE (or 2OE) is low.
If 1OE (or 2OE) is high, the outputs are in the
high-impedance state. 1OE (or 2OE) does not
affect the operation of the flip-flops. Previously
stored data can be retained or new data can be
entered
while
