MM74HC573WMX-L22178

Latches Overview

The MM74HC573WMX-L22178 is an octal D-type latch manufactured by onsemi, belonging to the HC logic series. It features a non-inverting configuration with three-state outputs housed in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 6 V. Propagation delay varies from 150 ns at 2 V to 26 ns at 6 V. Static current consumption is 8 µA, and high-level output current reaches -7.8 mA. Operating temperatures span from -40 °C to +85 °C.

Latches Feature Summary

• Octal D-type latch architecture providing eight independent data storage channels
• Three-state output capability allowing direct bus line interfacing
• Non-inverting signal polarity for straightforward digital logic integration

Latches Applications

• Digital data storage systems requiring parallel input retention
• Bus-oriented memory applications utilizing three-state control
• General-purpose latch circuits in industrial control environments

Latches Procurement Notes

Verify the specific suffix L22178 against official onsemi documentation to confirm manufacturing lot or tape-and-reel specifications. Ensure the 20-SOIC package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest release notes before finalizing procurement orders.

Latches Selection Notes

Select this component when an octal latch with low static power consumption is required. The HC series offers compatibility with standard CMOS logic levels across a wide voltage range. Consider the propagation delay characteristics relative to your system clock speed. Verify that the SOIC-20 package fits your available board space constraints.

Latches Part Context

This part belongs to the MM74HC573 family of octal latches produced by onsemi. It shares functional similarities with other HC-series devices but is distinguished by its specific packaging and suffix designations. The device serves as a fundamental building block for sequential logic circuits in digital electronics.

Latches Replacement Considerations

Compatible substitutes include the MM74HC573WM and MM74HC573N, provided pinouts and electrical characteristics align with your design requirements. Verify package compatibility and operating temperature ranges before substitution.
