Hot-selling and scarce 74ALS573BD Latch flip-flop SOP20 spot stock

Product Descriptions

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.

The data on the D inputs is transferred to the latch outputs when the enable (E) input is High. The latch remains transparent to the data input while E is High, and stores the data that is present one setup time before the High-to-Low enable transition.

The 74ALS574A is functionally identical to the 74ALS374 but has a broadside pinout configuration to facilitate PC board layout and allow easy interface with microprocessors.
