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
