The AC/ACT399 is the logical equivalent of a quad 2-input multiplexer feeding into four edge-triggered flip-flops.

A common Select input determines which of the two 4-bit words is accepted.

The selected data enters the flip-flop on the rising edge of the clock.

s ICC reduced by 50% s Select inputs from two data sources s Fully positive edge-triggered operation s Outputs source/sink 24 mA s AC/ACT399 has TTL-compatible inputs Ordering Code: Order Number Package Number Package.
