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

General Description

Features

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.

■ Inputs and outputs on opposite sides of package

allowing easy interface with microprocessors

■ Useful as input or output port for microprocessors

■ Functionally identical to ABT374

The device is functionally identical to the ABT374 but has

broadside pinouts.

■ 3-STATE outputs for bus-oriented applications

■ Output sink capability of 64 mA, source capability

of 32 mA

■ Guaranteed output skew

■ Guaranteed multiple output switching specifications

■ Output switching specified for both 50 pF and

250 pF loads

■ Guaranteed simultaneous switching, noise level and

dynamic threshold performance

■ Guaranteed latchup protection

■ High impedance glitch free bus loading during entire

power up and power down cycle

■ Non-destructive hot insertion capability
