74ALS574AN

Latch flip-flop

74ALS573B Octal transparent latch 3-State

74ALS574A Octal D flip-flop 3-State

DESCRIPTION

The 74ALS573B is an octal transparent latch coupled to eight 3-State output devices. The two sections of the device are controlled independently by enable E and output enable OE control gates. The 74ALS573B is functionally identical to the 74ALS373 but has a broadside pinout configuration to facilitate PC board layout and allow easy interface with microprocessors.

FEATURES

• 74ALS573B is broadside pinout version of 74ALS373

• 74ALS574A is broadside pinout version of 74ALS374

• Inputs and outputs on opposite side of package allow easy interface to microprocessors

• Useful as an input or output port for microprocessors

• 3-State outputs for bus interfacing

• Common output enable

• 74ALS563A and 74ALS564A are inverting version of 74ALS573B and 74ALS574A respectively
