SN74LV373APWRG4

Latches Overview

The SN74LV373APWRG4 is an octal transparent D-type latch manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V and supports mixed-mode port operation across all ports. The device features three-state outputs with low output impedance, designed for high-speed data latching in digital systems. It includes Ioff support for partial power-down mode, preventing damaging back-feeding when the device is powered down while connected to active lines. The component is housed in a 20-pin TSSOP package.

Latches Feature Summary

• Supports mixed-mode voltage operation on all ports
• Enables partial power-down via Ioff circuitry
• Provides three-state outputs for bus-driven applications

Latches Applications

• Printer interfaces
• Motor control systems
• Network switches
• Server motherboards
• Wireless infrastructure equipment

Latches Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm the TSSOP-20 package type matches the target PCB footprint. Ensure the operating voltage requirements align with the system's 2V to 5.5V specification. Check for any specific tape-and-reel packaging requirements if automated assembly is planned.

Latches Selection Notes

Select this component when an octal latch with mixed-voltage compatibility is required. The LV series offers lower power consumption compared to standard CMOS logic. Verify that the input levels are compatible with the driving source voltages. Consider the thermal performance of the TSSOP package for the intended application environment.

Latches Part Context

This part belongs to the SN74LV373A family of octal transparent latches. The 'G4' suffix indicates Green/RoHS-compliant manufacturing. It is part of Texas Instruments' broader portfolio of low-voltage CMOS logic devices designed for high-density digital applications requiring reliable data storage and bus interfacing capabilities.

Latches Replacement Considerations

Direct replacements include SN74LV373APW and SN74LV373APWR. Verify pinout compatibility and electrical specifications before substitution. Alternative packages such as SOIC may require adapter considerations.
