SN74HCS595DYYR

Shift Registers Overview

The SN74HCS595DYYR is an 8-bit serial-in, parallel-out shift register with a storage register and 3-state outputs. It operates within a supply voltage range of 2 V to 6 V and supports ambient temperatures from -40°C to +125°C. The device features Schmitt-trigger inputs for noise rejection and provides balanced CMOS push-pull outputs capable of ±7.8 mA drive current at 6 V. It utilizes a SOT-23-THIN (16) package.

Shift Registers Feature Summary

• Schmitt-trigger inputs eliminate erroneous data outputs caused by slow-edged or noisy input signals
• Balanced CMOS 3-state outputs allow high-impedance states controlled by the OE pin
• Low power consumption with typical supply current of 100 nA and input leakage of ±100 nA

Shift Registers Applications

• Output expansion
• LED matrix control
• 7-segment display control
• 8-bit data storage

Shift Registers Procurement Notes

Verify the specific DYY suffix corresponds to the SOT-23-THIN (16) package configuration. Confirm RoHS compliance status through official documentation. Ensure design accounts for the thermal resistance characteristics specific to this thin package variant during implementation.

Shift Registers Selection Notes

Select this component when noise immunity is required due to its Schmitt-trigger architecture. It is suitable for applications needing independent clocking for shift and storage registers. Consider the SOT-23-THIN package constraints regarding thermal dissipation and board space requirements compared to standard packages.

Shift Registers Part Context

This part belongs to the SN74HCS595 family, which includes variants in TSSOP, SOIC, WQFN, and SOT-23-THIN packages. All variants share identical electrical specifications and functionality, differing only in physical footprint and thermal properties. The DYY suffix specifically denotes the SOT-23-THIN form factor.

Shift Registers Replacement Considerations

Other SN74HCS595 variants such as SN74HCS595PW, SN74HCS595D, and SN74HCS595BQB are functionally equivalent but utilize different packages.
