54ABT574 Octal D-Type Flip-Flop with TRI-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 except for the pinouts. 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) 5962-9322001
Features
n Inputs and outputs on opposite sides of package allowing easy interface with microprocessors n Useful as input or output port for microprocessors n Functionally identical to ’ABT374
