description
The ’AC16824 and ’ACT16824 are inverting 18-bit
D-type flip-flops composed of two 9-bit sections
with separate control signals. For either 9-bit
flip-flop section, if the clock enable (1CLKEN or
2CLKEN) is low, the inverse of the data present at
the corresponding D inputs is stored in the
flip-flops on the rising edge of 1CLK (or 2CLK).
When 1CLKEN (or 2CLKEN) is high, the flip-flops
retain their previously stored values. Taking 1CLR
(or 2CLR) ) low asynchronously clears the
corresponding flip-flops.
When the output enable (1OE or 2OE) is low, the corresponding Q outputs are active (high or low logic levels).
When 1OE (or 2OE) is high, the corresponding outputs are in the high-impedance state. 1OE (or 2OE) does
not affect the internal operation of the flip-flops: previously stored data can be retained or new data can be
entered while the outputs are in the high-impedance state.
