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.
