SN74LVTH373PWRG4

Overview

The SN74LVTH373PWRG4 is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the LVTH logic series. It features a TSSOP-20 package and operates within a supply voltage range of 2.7 V to 3.6 V. The device exhibits a propagation delay of 2.6 ns at 3.3 V and supports low-level output currents of 32 mA and high-level output currents of -32 mA. It functions as a non-inverting circuit with eight input and eight output lines, operating reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides bus structure support through three-state outputs for efficient system integration.
• Incorporates bus-hold data inputs to maintain unused input states without external pull-up resistors.
• Utilizes advanced BiCMOS technology to achieve high-speed performance comparable to 5V ABT while maintaining low CMOS power consumption.

Applications

• Bus-oriented memory mapping
• Clock buffering
• Bus driving

Procurement Notes

Verify the RoHS compliance status and specific datasheet revisions prior to procurement. Confirm that the TSSOP-20 package dimensions align with the target PCB footprint. Ensure the operating voltage requirements match the 2.7 V to 3.6 V specification range. Validate thermal management capabilities for the intended ambient temperature conditions.

Selection Notes

Select this component when designing systems requiring 3.3 V operation with TTL-compatible interfaces. The LVTH series offers superior speed compared to standard LVT devices. Consider the bus-hold feature if minimizing external components is a priority. Verify compatibility with existing 5 V environments if level shifting is required.

Part Context

This part is a green (RoHS compliant) version of the SN74LVTH373PWR. It belongs to the Texas Instruments SN74LVTH373 family of octal transparent latches. The 'G4' suffix indicates environmental compliance, distinguishing it from earlier manufacturing versions while maintaining identical electrical and functional specifications.

Replacement Considerations

SN74LVTH373PWRE4 is a verified direct replacement with identical functionality and packaging.
