Octal D-Type Flip-Flop with TRI-STATE Outputs
General Description
The ’F374 is a high-speed low-power octal D-type flip-flop
featuring separate D-type inputs for each flip-flop and
TRI-STATE outputs for bus-oriented applications A buff-
ered Clock (CP) and Output Enable (OE) are common to all
flip-flops
