SN74LS373NSR

Latches Overview

The SN74LS373NSR is an octal transparent D-type latch from the Texas Instruments SN74LS series. It features eight D-type latches with non-inverting outputs and three-state capability. The device operates within a supply voltage range of 4.75 V to 5.25 V. It utilizes an SOIC-20 surface-mount package. Key electrical parameters include a propagation delay of 18 ns at 5 V, a low-level output current of 32 mA, and a high-level output current of -2.6 mA. The operating temperature range spans from 0°C to +70°C.

Latches Feature Summary

• Octal configuration providing eight independent D-type latches for parallel data storage.
• Three-state outputs allow direct connection to system buses without external buffers.
• Transparent latch mode enables data to pass through when the latch enable is active.

Latches Applications

• Parallel-to-serial conversion circuits
• Bus-oriented memory mapping
• Temporary data storage in digital systems

Latches Procurement Notes

Verify the specific suffix 'SR' corresponds to the SOIC-20 tape-and-reel packaging format. Confirm RoHS compliance status as indicated in official documentation. Ensure the supplier provides valid traceability for the Texas Instruments manufacturing origin. Check for any specific handling requirements associated with surface-mount components.

Latches Selection Notes

Select this component when an octal latch with bus-compatible three-state outputs is required. The LS logic family offers standard speed suitable for general-purpose digital applications. Consider the SOIC-20 package for surface-mount assembly constraints. Verify that the 5V supply voltage aligns with the target system architecture.

Latches Part Context

This part belongs to the SN74LS373 family of octal transparent latches. It shares functional compatibility with other variants such as SN74LS373N (PDIP) and SN74LS373DWR (SOIC). The primary distinction lies in the package type and reel quantity rather than internal circuitry or logical function.

Latches Replacement Considerations

SN74LS373DWR serves as a direct functional substitute with identical specifications in an SOIC-20 package. SN74LS373NE4 is available for through-hole applications using a PDIP-20 package.
