Octal D-Type Flip-Flop with TRI-STATEÉ Outputs
General Description
The ’F534isa high speed, low-power octal D-type flip-flop
featuring separate D-type inputsfor each flip-flop and
TRI-STATE outputsfor bus-oriented applications.A buff-
ered Clock (CP)and Output Enable (OE)are commontoall
flip-flops. The ’F534isthe sameasthe ’F374 exceptthat
the outputsare inverted.
Features Edge-triggered D-type inputs Buffered positive edge-triggered clock TRI-STATE outputsfor bus-oriented applications Guaranteed 4000V minimum ESD protection
