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. 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
Features
n n n n Edge-triggered D-type inputs Buffered positive edge-triggered clock TRI-STATE outputs for bus-oriented applications Output sink capability of 48 mA, source capability of 24 mA
