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.
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
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
