SN74AHC373NSR

Overview

The SN74AHC373NSR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the AHC logic series. It features a 20-pin SOIC package and operates with non-inverting outputs. The device supports a supply voltage range of 2 V to 5.5 V and functions within temperatures from -40°C to +85°C. Key electrical parameters include a propagation delay of 14.9 ns or 9.2 ns, static current of 4 uA, low-level output current of 32 mA, and high-level output current of -8 mA.

Feature Summary

• Provides eight independent transparent D-type latches for data storage applications
• Operates across a wide supply voltage range from 2 V to 5.5 V
• Features low static power consumption characteristics typical of AHC technology

Applications

• Parallel-to-serial data conversion circuits
• Temporary data storage in digital systems
• Interface buffering between microprocessors and peripheral devices

Procurement Notes

Verify the specific suffix 'SR' indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct logic family and package type. Check RoHS compliance documentation if required for your assembly process. Ensure the operating temperature range meets your environmental specifications.

Selection Notes

Select this component when eight parallel latches are needed in a small surface-mount package. The AHC series offers faster switching speeds compared to standard HC logic while maintaining compatibility. Consider the 20-pin SOIC footprint for PCB layout constraints. Verify input voltage levels match your system logic standards.

Part Context

This part belongs to the SN74AHC373 family of octal D-type latches. It shares functional similarities with other variants like SN74AHC373DWR but differs in package style. The NSR designation specifically identifies the SOIC-20 surface-mount configuration. It is designed for general-purpose digital logic applications requiring reliable data retention.
