54ABT374
Octal D-Type Flip-Flop with TRI-STATE® Outputs
General Description
The ’ABT374 is an octal D-type flip-flop featuring separate
D-type inputs for each flip-flop and TRI-STATE outputs for
bus-oriented applications. A buffered Clock (CP) and Output
Enable (OE) are common to all flip-flops.
Features
n Edge-triggered D-type inputs
n Buffered positive edge-triggered clock
n TRI-STATE outputs for bus-oriented applications
n Output sink capability of 48 mA, source capability of
24 mA
n Guaranteed multiple output switching specifications
n Output switching specified for both 50 pF and 250 pF
loads
n Guaranteed simultaneous switching, noise level and
dynamic threshold performance
n Guaranteed latchup protection
n High impedance glitch free bus loading during entire
power up and power down cycle
n Non-destructive hot insertion capability
n Standard Microcircuit Drawing (SMD) 5962-9314901
