74ABT374
Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The ABT374 is an octal D-type flip-flop featuring separate
D-type inputs for each flip-flop and 3-STATE outputs for
bus-oriented applications. A buffered Clock (CP) and Out-
put Enable (OE) are common to all flip-flops.
Features
s Edge-triggered D-type inputs
s Buffered positive edge-triggered clock
s 3-STATE outputs for bus-oriented applications
s Output sink capability of 64 mA, source capability of
32 mA
s Guaranteed output skew
s Guaranteed multiple output switching specifications
s Output switching specified for both 50 pF and 250 pF
loads
s Guaranteed simultaneous switching, noise level and
dynamic threshold performance
s Guaranteed latchup protection
s High impedance glitch free bus loading during entire
power up and power down cycle
s Non-destructive hot insertion capability
