MC74VHC373M

Latches Overview

The MC74VHC373M is an octal D-type latch manufactured by onsemi, belonging to the 74VHC logic family. It features eight non-inverting D-type latches with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 5.5 V and supports a maximum quiescent current of 4 µA. Propagation delays are specified at 14.9 ns and 9.2 ns under 3.3 V conditions. It provides high noise immunity and includes power-down protection on all inputs.

Latches Feature Summary

• Octal configuration providing eight independent D-type latches with three-state output control
• High-speed operation capability suitable for demanding digital applications
• Power-down protection integrated on all input pins to prevent undefined states during low-power modes

Latches Applications

• Data storage and buffering in high-speed digital systems
• Interface circuits requiring tri-state output isolation
• Memory address latching in microprocessor-based designs

Latches Procurement Notes

Verify component authenticity through authorized distribution channels due to potential counterfeit risks. Confirm RoHS compliance status via official manufacturer documentation before integration. Ensure proper handling procedures are followed as the component may be sensitive to electrostatic discharge. Review datasheet specifications thoroughly to validate suitability for specific operating temperature and voltage requirements.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required within the 74VHC family specifications. Consider the 20-pin SOIC package dimensions for PCB layout compatibility. Evaluate propagation delay characteristics against system timing constraints. Verify that the 2 V to 5.5 V operating range aligns with the target application power supply design.

Latches Part Context

This part belongs to the 74VHC series of high-speed CMOS logic devices produced by onsemi. The 74VHC family offers performance comparable to TTL while maintaining low power consumption typical of CMOS technology. The MC74VHC373M specifically implements the standard octal D-latch function with enhanced speed characteristics relative to earlier generations.

Latches Replacement Considerations

Direct substitutes include other manufacturers' 74VHC373 variants in SOIC-20 packages. Cross-reference pinouts and electrical specifications carefully when considering alternatives from different vendors to ensure functional compatibility.
