54F 74F534
Octal D-Type Flip-Flop with TRI-STATE Outputs
General Description
The ’F534 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 ’F534 is the same as the ’F374 except that
the outputs are inverted
Features
Y _{Edge-triggered D-type inputs}
Y _{Buffered positive edge-triggered clock}
Y _{TRI-STATE outputs for bus-oriented applications}
Y _{Guaranteed 4000V minimum ESD protection}
