SN74LV373ATNSR

Latches Overview

The SN74LV373ATNSR is an octal transparent D-type latch with three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2V to 5.5V, supporting mixed-mode port operation for interfacing between different voltage domains. The device features low output impedance and supports local shutdown mode via Ioff circuitry. It is designed for high-speed applications with a maximum propagation delay of 8.5ns at 5V. The component is housed in a 20-TSSOP package and complies with RoHS standards.

Latches Feature Summary

• Supports mixed-mode voltage operation across all ports
• Enables local shutdown mode through Ioff circuitry
• Provides three-state outputs for bus-driven applications

Latches Applications

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

Latches Procurement Notes

Verify the specific suffix 'TNSR' against the official datasheet to confirm the TSSOP-20 package and tape-and-reel packaging configuration. Ensure the operating temperature range matches the design requirements, as industrial variants may differ. Confirm RoHS compliance status directly from the manufacturer's documentation before procurement.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for data buffering or register applications. It is suitable for designs needing compatibility with both 3.3V and 5V logic levels due to its wide supply voltage range. Consider the TSSOP package size constraints and thermal performance during PCB layout.

Latches Part Context

This part belongs to the SN74LV373A family of octal transparent D-type latches. It shares functional similarities with other members like SN74LV373APWR but differs in package type (TSSOP vs. TSSOP/TSSOP) and reel specifications. The LV series is characterized by low voltage operation and high speed compared to standard 74LS or 74HC families.
