SN74LVC373APWRG4

Latches Overview

The SN74LVC373APWRG4 is an octal transparent D-type latch with 3-state outputs manufactured by Texas Instruments. It operates from a supply voltage of 1.65 V to 3.6 V and accepts input voltages up to 5.5 V, supporting mixed-mode signal operation. The device features a maximum propagation delay of 6.8 ns at 3.3 V and includes Ioff circuitry for partial-power-down mode. It provides ESD protection exceeding 2000 V via the human-body model and latch-up performance exceeding 250 mA per JESD 78 standards.

Latches Feature Summary

• Supports mixed-mode signal operation with inputs accepting voltages up to 5.5 V while operating on lower supply rails
• Includes Ioff circuitry to disable outputs during partial-power-down, preventing damaging back-drive current
• Provides high electrostatic discharge protection exceeding 2000 V under the human-body model standard

Latches Applications

• Network switches
• TV set-top boxes
• Motor drives
• PCs and notebooks

Latches Procurement Notes

Verify the specific package variant matches the required footprint, as the PW designation indicates TSSOP-20. Confirm RoHS compliance and lead finish specifications against project requirements. Ensure ordering quantities align with manufacturer packaging constraints. Validate that the G4 suffix corresponds to the intended environmental and manufacturing standards before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring data retention in bus-interface applications with mixed voltage domains. The 5.5 V tolerant inputs allow direct interfacing between 3.3 V logic and 5 V peripherals without additional level shifters. Consider the low power consumption and high drive capability suitable for driving multiple loads or high-speed buses up to 100 MHz.

Latches Part Context

This part belongs to the SNx4LVC373A family of octal transparent D-type latches. The 'G4' suffix denotes compliance with specific environmental and manufacturing guidelines established by Texas Instruments. The 'PW' suffix identifies the 20-pin Thin Shrink Small Outline Package (TSSOP). This series is designed for low-voltage CMOS applications requiring high drive strength and fast switching speeds.

Latches Replacement Considerations

Direct replacements include SN74LVC373ADW and SN74LVC373ARGYR. Verify pin compatibility and thermal characteristics when substituting packages such as SOIC or VQFN variants.
