54F 74F534
Octal D-Type Flip-Flop with TRI-STATE Outputs
General Description
The 鈥橣534 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 The 鈥橣534 is the same as the 鈥橣374 except that
the outputs are inverted
