This is the standard part for expanding microcontroller GPIO — you get eight extra outputs from three MCU pins (data, clock, latch). The tri-state outputs let you share a bus with other devices without contention. Surface-mount 16-SOIC package (7.50 mm body width) is the wide-body variant, giving better thermal and creepage than the narrow SOIC-16. ## Cascading and output control The serial output pin (QH') lets you cascade multiple SN74HC595DW devices — chain them to drive 16, 24, or more outputs from the same three MCU lines. Each device adds eight outputs. The master reset (SRCLR) and output enable (OE) pins give you global control: OE tristates all outputs without shifting data out, useful for power-up sequencing or bus sharing. This part is a standard catalog item from Texas Instruments, widely stocked across distribution.","metaTitle":"SN74HC595DW 8-bit shift register, 2V-6V, -40°C to 85°C","metaDescription":"Texas Instruments SN74HC595DW 8-bit serial-in parallel-out shift register with tri-state outputs. 2V-6V supply, -40°C to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":"74HC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Mfr":"Texas Instruments","Series":"74HC","Package":"Tube","Function":"Serial to Parallel, Serial","Logic Type":"Shift Register","Output Type":"Tri-State","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 6V","Number of Elements":"1","Base Product Number":"74HC595","Operating Temperature":"-40°C~85°C","Supplier Device Package":"16-SOIC","Number of Bits per Element":"8"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1700","priceTiers":[{"qty":1,"price":"$1.17000","currency":"USD"},{"qty":10,"price":"$1.04800","currency":"USD"},{"qty":25,"price":"$0.99440","currency":"USD"},{"qty":100,"price":"$0.81670","currency":"USD"},{"qty":250,"price":"$0.76348","currency":"USD"},{"qty":500,"price":"$0.67468","currency":"USD"},{"qty":1000,"price":"$0.53265","currency":"USD"},{"qty":2500,"price":"$0.50250","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a21d231201599cca020fc991b72e8ea9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN74HC595DW/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN74HC595DW and SN74HC595N?","answer":"The SN74HC595N is the same 8-bit shift register in a through-hole PDIP-16 package, while the SN74HC595DW is the surface-mount 16-SOIC wide-body variant.
