74LCX573WMX

Latches Overview

The onsemi 74LCX573WMX is an octal transparent D-type latch featuring three-state outputs, designed for low-voltage digital applications. It operates within a supply voltage range of 2.0 V to 3.6 V and supports 5-V tolerant inputs and outputs, facilitating interface between low-voltage logic and higher-voltage systems. The device incorporates Schmitt-trigger action on all inputs to ensure noise immunity and clean switching transitions. Packaged in a 20-lead SOIC surface-mount format, it delivers high-speed performance with propagation delays as low as 1.5 ns at 3.3 V while maintaining ultra-low static power consumption.

Latches Feature Summary

• Features 5-V tolerant inputs and outputs allowing direct interfacing with 5-V CMOS devices from a lower voltage supply.
• Incorporates Schmitt-trigger input circuitry to provide enhanced noise filtering and stable signal integrity.
• Provides three-state outputs that enable direct connection to bus lines without additional buffer drivers.
• Delivers high-speed operation with propagation delays comparable to standard 5-V TTL logic families.

Latches Applications

• Data register and buffering in portable battery-powered electronic equipment
• Bus-oriented memory mapping and address latching in computing systems
• Clock distribution and timing control circuits requiring precise data storage
• Interface bridging between low-voltage processors and 5-V peripheral devices

Latches Procurement Notes

Verify the specific suffix 'WMX' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint dimensions and soldering profile requirements. Confirm RoHS compliance status for your target market regulations. Check for any recent lifecycle notices or obsolescence warnings directly from onsemi documentation before finalizing procurement plans.

Latches Selection Notes

Select this component when designing systems requiring low-power operation combined with 5-V tolerance capabilities. It serves as a suitable replacement for legacy 74HC573 or 74HCT573 devices where reduced supply voltage is necessary. Consider its propagation delay characteristics relative to your system clock speed. Evaluate the SOIC-20 package constraints against available board space and thermal management requirements for your specific application environment.

Latches Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic integrated circuits manufactured by onsemi. The LCX family is engineered to provide performance levels similar to traditional 5-V logic while operating at significantly lower voltages. This specific model represents an octal latch configuration, widely used in digital design for temporary data storage and signal isolation within complex electronic architectures.

Latches Replacement Considerations

Direct substitutes include MC74LCX573DWG and MC74LCX573DWR2G from onsemi, which share identical logical functionality and pinout configurations. Other compatible alternatives may include SN74LVC573ADWR from Texas Instruments or STMicroelectronics 74LCX573MTR, provided voltage tolerances and package dimensions are verified against the original design specifications.
