Key Features
- Schmitt-trigger inputs provide enhanced noise immunity for reliable data capture in electrically noisy industrial and automotive environments
- 3-state outputs with active-low output enable allow multiple latches to share a common data bus without bus contention
- Octal (8-bit) transparent D-type latch captures and holds parallel data for microcontroller address and data bus interfacing
- Compact 20-pin VQFN package enables space-efficient placement while supporting -40°C to +125°C extended temperature operation
Applications
The SN74HCS573RKSR is used in microcontroller and FPGA systems for address bus demultiplexing and parallel data latching, enabling stable data capture during address/data bus strobe cycles in embedded processor designs. It is also applied in industrial control panels, automotive body electronics, and communication modules where Schmitt-trigger inputs prevent false triggering from line noise. Memory interface boards and display controller circuits use this device to buffer and hold 8-bit data words before transferring them to slower peripheral buses.

Frequently Asked Questions
What are the key features of the SN74HCS573RKSR?
The SN74HCS573RKSR features octal 8-bit D-type transparent latches with Schmitt-trigger inputs for improved noise immunity, 3-state outputs for bus sharing, active-low output enable, and operation from -40°C to +125°C in a compact 20-pin VQFN package.
What logic family does the SN74HCS573RKSR belong to?
The SN74HCS573RKSR is part of the HC/UH (High-speed CMOS) logic family, providing low power consumption, wide supply voltage compatibility, and full compatibility with LVTTL and CMOS input logic levels.
What is the output configuration of the SN74HCS573RKSR?
The SN74HCS573RKSR has 3-state outputs controlled by an active-low output enable (OE) pin. When OE is high, all outputs are placed in a high-impedance state, allowing multiple devices to share a common data bus without driving it simultaneously.
What package does the SN74HCS573RKSR come in?
The SN74HCS573RKSR is available in a 20-pin VQFN (Very Thin Quad Flat No-lead) surface mount package, which provides an excellent thermal path and a compact PCB footprint suitable for high-density digital system designs.
What is the advantage of the Schmitt-trigger inputs on the SN74HCS573RKSR?
The Schmitt-trigger inputs on the SN74HCS573RKSR provide hysteresis that makes the device immune to slow input rise times and electrical noise, preventing false triggering and ensuring reliable data latching even in noisy industrial and automotive environments.
