74AC399 74ACT399  
Quad 2-Port Register  
General Description  
Features  
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.  
ICC reduced by 50%  
Select inputs from two data sources  
Fully positive edge-triggered operation  
Outputs source/sink 24 mA  
AC/ACT399 has TTL-compatible inputs
