74VHC373MTC

Latches Overview

The onsemi 74VHC373MTC is an octal D-type latch featuring three-state outputs, housed in a 20-pin TSSOP package. It operates within a supply voltage range of 2 V to 5.5 V and supports a wide operating temperature from -40°C to +85°C. The device exhibits a maximum quiescent current of 4 µA and provides high-level output currents of -8 mA. Propagation delays are specified at 14.9 ns and 9.2 ns under 3.3 V conditions.

Latches Feature Summary

• Octal configuration with eight independent D-type latches and non-inverting polarity.
• Three-state outputs enable direct bus-driven connections without external drivers.
• Power-down protection prevents unintended current flow on inputs during low-power states.

Latches Applications

• Data register storage in digital logic circuits
• Bus-oriented memory applications
• Temporary data holding for microprocessor systems

Latches Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Ensure the specific suffix matches required packaging formats. Validate pinout compatibility with existing PCB footprints. Review datasheet revisions for any functional updates prior to final design approval.

Latches Selection Notes

Select this component when requiring high-speed latching with low power consumption in compact surface-mount designs. The 74VHC series offers superior speed compared to standard HC logic while maintaining CMOS input characteristics. Consider the TSSOP-20 package for space-constrained layouts. Verify voltage levels match system requirements across the full operating temperature range.

Latches Part Context

This part belongs to the 74VHC373 family of octal D-type latches manufactured by onsemi. It shares functional similarities with other variants like the 74VHC373MX but differs in packaging. The 74VHC series is designed for high-speed applications requiring low power dissipation and robust noise immunity in modern digital systems.

Latches Replacement Considerations

MC74VHC373DTR2G is listed as a direct replacement option. Verify pinout and electrical specifications against original requirements before substitution. Ensure the alternative component meets all environmental and performance criteria for the intended application.
