Product Overview
The SN74HC595 is a Texas Instruments 8-bit serial-in, parallel-out shift register in the Logic category. Its device structure combines an 8-bit serial shift register with an 8-bit D-type storage register, and the storage register drives parallel 3-state outputs QA through QH. This supports serial data loading followed by parallel output presentation under the stated timing limits.
Recommended operation covers a 2 V to 6 V supply range, with 5 V specified as the nominal supply voltage and -40°C to 85°C free-air temperature operation. Input and output voltage ranges are 0 V to VCC, while logic input thresholds vary with supply voltage, including VIH minimums of 1.5 V at 2 V, 3.15 V at 4.5 V, and 4.2 V at 6 V.
Available package cases include PDIP-16, SOIC-16, SSOP-16, TSSOP-16, LCCC-20, and CDIP-16 body sizes. Timing data includes up to 25 MHz clock operation at 4.5 V and 29 MHz at 6 V, with specified pulse duration, setup, hold, propagation, enable, and disable timing for shift-register and storage-register control.

Procurement Notes
When requesting a quote for SN74HC595, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For MCU, processor and logic IC sourcing, package, operating voltage, temperature grade, speed or frequency grade, firmware or mask version, lifecycle status and programming requirements should be checked before approval.
