74AC399
74ACT399
Quad 2-Port Register
General Description
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.
