74ABT574 Octal D-Type Flip-Flop with 3-STATE Outputs

November 1992 Revised March 2005

74ABT574 Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The ABT574 is an octal flip-flop with a buffered common Clock (CP) and a buffered common Output Enable (OE). The information presented to the D inputs is stored in the flip-flops on the LOW-to-HIGH Clock (CP) transition. The device is functionally identical to the ABT374 but has broadside pinouts.

Features
s Inputs and outputs on opposite sides of package allowing easy interface with microprocessors s Useful as input or output port for microprocessors s Functionally identical to ABT374 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
