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
