Quad 2-Port Register
74AC399 • 74ACT399 Quad 2-Port Register June 1988 Revised October 2000 74AC399 74ACT399 Quad 2-Port Register General Description Features The AC/ACT399 is the logical equivalent of a quad 2-inputI reduced by 50% CC multiplexer feeding into four edge-triggered flip-flops. A Select inputs from two data sources common Select input determines which of the two 4-bit Fully positive edge-triggered operation words is accepted. The selected data enters the flip-flop on Outputs source/sink 24 mA the rising edge of the clock.
