SN74LVTH373NSR

Latches Overview

The SN74LVTH373NSR is an octal D-type transparent latch manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 2.7 V to 3.6 V and supports a wide operating temperature range from -40°C to +85°C. The device utilizes a 20-pin Small Outline Integrated Circuit (SOIC) package with surface-mount technology. It belongs to the LVTH logic series, designed for low-voltage applications requiring TTL-compatible inputs.

Latches Feature Summary

• Provides eight independent D-type latches with transparent data flow when enabled.
• Features three-state outputs to facilitate direct connection to bus systems.
• Supports operation at low supply voltages while maintaining TTL-compatible input thresholds.

Latches Applications

• Bus-oriented memory mapping
• Registering and buffering data in low-voltage systems
• Driving high-capacitance or low-impedance loads

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type, tape-and-reel specifications, and environmental compliance status. Ensure the component matches the required voltage and temperature ratings for the target application environment before procurement.

Latches Selection Notes

Select this component for designs requiring octal latching with bus-driven capabilities in low-voltage environments. Compare propagation delay and output drive strength against system timing requirements. Verify that the SOIC-20 package dimensions fit the available PCB footprint constraints.

Latches Part Context

This part belongs to the SN74LVTH373 family of octal D-type latches. It shares functional similarities with other members like the SN74LVTH374 but differs in triggering mechanism and output configuration. The LVTH series is optimized for 3.3V systems, offering compatibility with both 3.3V and 5V devices through TTL-compatible inputs.

Latches Replacement Considerations

Check for pin-compatible alternatives such as the SN74ACT373 or SN74AC373 if higher speed or different voltage levels are required. Verify electrical characteristics and package dimensions before substituting.
