MC74HCT573ADWR2G-Q

Latches Overview

The MC74HCT573ADWR2G-Q is an octal 3-state non-inverting transparent latch manufactured by onsemi. It utilizes high-performance silicon-gate CMOS technology and features LSTTL-compatible inputs for robust interfacing. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum propagation delay of 45 ns. It provides eight outputs capable of sinking and sourcing up to 6 mA each. Packaged in a 20-pin SOIC, it supports surface-mount installation and functions reliably across an extended temperature range from -55°C to +125°C.

Latches Feature Summary

• Features LSTTL-compatible inputs for direct interface with TTL logic systems
• Provides three-state output control for bus-oriented memory addressing
• Utilizes high-performance silicon-gate CMOS technology for low power consumption

Latches Applications

• Bus-oriented memory systems requiring data latching
• I/O port circuits for microprocessor-based designs
• Register files in digital signal processing applications

Latches Procurement Notes

Verify the specific suffix 'Q' indicates automotive or qualified status requirements against your design specifications. Confirm the SOIC-20 package dimensions match your PCB footprint. Ensure the 4.5V to 5.5V operating voltage aligns with your system power rails. Check RoHS compliance documentation for environmental regulations. Validate the extended temperature range suitability for your operational environment.

Latches Selection Notes

Select this component when LSTTL input compatibility is required alongside CMOS low power benefits. The 3-state outputs facilitate efficient bus sharing in multi-device systems. Consider the 45 ns propagation delay for timing constraints in your application. The wide operating temperature range supports harsh environments. Ensure the 6 mA drive current meets the load requirements of connected devices.

Latches Part Context

This part belongs to the MC74HCT573A series of octal latches. It shares pinout compatibility with standard 74HCT573 devices but includes specific qualification markings indicated by the 'Q' suffix. The series is designed for general-purpose digital logic applications requiring reliable data storage and transfer capabilities in industrial and automotive contexts.

Latches Replacement Considerations

Direct substitutes include other MC74HCT573 variants with compatible packages. Verify equivalent electrical characteristics such as propagation delay and output current. Ensure the replacement maintains the same 3-state functionality and LSTTL input levels. Check for identical package dimensions and pin configurations.
