SN74LV373APWRE4

Latches Overview

The SN74LV373APWRE4 is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the LV logic series. It operates within a supply voltage range of 2.7 V to 3.6 V and features non-inverting polarity with eight input and output lines housed in a TSSOP-20 package. 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 reliably across an operating temperature range from -40°C to +85°C.

Latches Feature Summary

• Supports mixed-mode operation across all ports for flexible interface compatibility
• Provides local shutdown capability through Ioff support for safe power-down states
• Delivers robust latch performance exceeding 250 mA to meet JESD 17 standards

Latches Applications

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

Latches Procurement Notes

Verify the specific RE4 suffix against official documentation to confirm it denotes a standard RoHS-compliant variant without functional deviation from the base SN74LV373APWR model. Ensure the TSSOP-20 package dimensions align with PCB footprint requirements. Confirm that the 3.3 V nominal voltage range matches the target system's power rails before finalizing procurement specifications.

Latches Selection Notes

Select this component when designing systems requiring octal latching with mixed-voltage port capabilities. It is suitable for applications needing high drive strength and fast switching speeds within a 3.3 V environment. Consider the TSSOP-20 package for surface-mount assembly constraints. Verify thermal management needs given the specified operating temperature limits and output current capabilities.

Latches Part Context

This part belongs to the SN74LV373A family of octal transparent D-type latches designed for low-voltage CMOS operations. The RE4 suffix typically indicates a lead-free, RoHS-compliant manufacturing version. It serves as a digital storage element for bus holding and data retention in high-speed logic interfaces.

Latches Replacement Considerations

SN74LV373APWR is the primary equivalent without the environmental suffix. SN74LVTH373PWRE4 offers similar functionality but operates at different voltage levels.
