SN74HCS373DGSR

Overview

The SN74HCS373DGSR is an octal transparent D-type latch with Schmitt-trigger inputs and three-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an extended ambient temperature range from –40°C to +125°C. The device features balanced CMOS outputs capable of ±7.8-mA drive at 6 V, low power consumption with typical ICC of 100 nA, and input leakage current of ±100 nA. It is housed in a 20-pin VSSOP (DGS) package.

Feature Summary

• Schmitt-trigger inputs provide tolerance for slow or noisy signals
• Balanced CMOS three-state outputs allow high-impedance states
• Extended operating temperature range up to +125°C

Applications

• Parallel data storage
• Digital bus buffer

Procurement Notes

Verify the specific ordering suffix DGSR corresponds to the VSSOP-20 package and tape-and-reel quantity when sourcing. Confirm that the supply voltage and load conditions align with the recommended operating conditions to ensure proper functionality. Check for any recent documentation updates regarding pin configurations or thermal characteristics before finalizing procurement.

Selection Notes

Select this component when noise immunity is required due to its Schmitt-trigger architecture. Ensure the application demands an extended temperature range up to +125°C. Verify that the 2 V to 6 V supply voltage range matches the system design. Consider the VSSOP package size constraints and thermal requirements for the specific PCB layout.

Part Context

This part belongs to the SN74HCS373 family of octal transparent D-type latches. It shares functional similarities with other logic families but distinguishes itself through Schmitt-trigger inputs and wide voltage operation. The DGSR suffix indicates a surface-mount VSSOP package variant designed for automated assembly processes.

Replacement Considerations

Direct substitutes include other SN74HCS373 variants with different packages such as RKS or DGS if reel quantities differ. Cross-reference with SN74HC373 or SN74HCT373 only if Schmitt-trigger inputs are not strictly required and voltage ranges align.
