NLV74HC573ADTR2G

Latches Overview

The NLV74HC573ADTR2G is an octal transparent latch manufactured by onsemi, belonging to the automotive-grade 74HC logic series. It features eight non-inverting D-type latches with three-state outputs housed in a 20-TSSOP package. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55 °C to +125 °C. Key electrical parameters include a maximum propagation delay of 30 ns at 4.5 V and a static current of 4 µA. Output drive capabilities provide low-level currents up to 32 mA and high-level currents up to -7.8 mA.

Latches Feature Summary

• Automotive-grade qualification ensuring reliability for demanding vehicle environments
• Transparent latch operation allowing direct data passage when enabled
• Three-state outputs facilitating bus-oriented memory and communication systems

Latches Applications

• Automotive electronic control units requiring robust data storage
• Bus-oriented memory applications in vehicle networks
• Communication systems within automotive architectures

Latches Procurement Notes

Verify that the specific part number suffix indicates automotive grade compliance, as standard commercial variants may lack the required temperature and reliability specifications. Confirm RoHS status and material declarations against current manufacturer documentation to ensure regulatory adherence. Cross-reference the datasheet revision history to validate performance characteristics match the intended design requirements before finalizing procurement.

Latches Selection Notes

Select this component when automotive environmental resilience is mandatory alongside standard HC logic compatibility. The wide voltage range supports various power domains within vehicle electronics. Ensure the TSSOP-20 package fits the available PCB footprint. Compare propagation delays against system timing constraints to verify signal integrity across the specified temperature range.

Latches Part Context

This component is part of onsemi's extended automotive logic portfolio, designed to meet stringent AEC-Q100 standards. It complements other 74HC family members by providing specialized functionality for automotive data handling. The NLV prefix specifically denotes the automotive grade variant, distinguishing it from commercial equivalents in terms of manufacturing controls and long-term availability.

Latches Replacement Considerations

Direct substitutes include MC74HC573ADTR2G for commercial grade or MC74HCT573ADTR2G for HCT logic compatibility. Verify pinout and electrical specifications carefully when substituting between different logic families or grades.
