Applications
The SN74HC573ADW is widely used in microprocessor and microcontroller address/data bus buffering, where its 3-state outputs allow multiple devices to share a common bus without conflict. It is also deployed in memory interfaces, programmable logic controllers, and industrial I/O expansion boards that require reliable 8-bit data latching. Its broad 2V–6V supply range makes it suitable for both 3.3V and 5V mixed-signal designs in consumer electronics, communications equipment, and embedded systems.

Frequently Asked Questions
What is the operating voltage range of the SN74HC573ADW?
The SN74HC573ADW operates from a supply voltage (VCC) of 2V to 6V, making it compatible with both 3.3V and 5V logic systems. This wide range provides design flexibility for mixed-voltage environments in embedded and industrial applications.
How does the output enable pin work on the SN74HC573ADW?
The SN74HC573ADW features an active-low output enable (OE) pin. When OE is held LOW, the 8 latch outputs reflect the stored data state. When OE is driven HIGH, all outputs enter a high-impedance (3-state) condition, allowing multiple devices to share the same data bus without bus contention.
What is the difference between SN74HC573ADW and SN74HC373?
The SN74HC573ADW is the broadside (wide-body SOIC) version of the SN74HC373. Both are octal D-type transparent latches with 3-state outputs and identical logic functions. The key difference is pinout orientation: the 573 has all data inputs on one side and all outputs on the other, simplifying PCB layout compared to the 373's interleaved pin arrangement.
What package does the SN74HC573ADW come in and what are its dimensions?
The SN74HC573ADW is available in a 20-pin SOIC (Small Outline IC) package, designated by the 'DW' suffix. This wide-body surface-mount package offers a compact footprint suitable for high-density PCB designs, with a standard 1.27mm pin pitch and body width of approximately 7.5mm.
