It handles parallel-to-serial and serial-to-parallel data conversion with left/right shift and parallel load capability, all in a push-pull output stage. ## Supply voltage and temperature — the two specs that decide fit The 2V to 6V supply range is the headline selector. If your board runs a 3.3V rail, this part works without a regulator swap; if you are on a 5V legacy bus, it sits right in the middle. That means the same BOM line serves a lab prototype and a satellite payload, as long as the rest of the board can take the temperature. No derating needed for cold-crank or engine-bay heat soak. ## Package and footprint — what to expect on the board It comes in a 16-TSSOP body (0.173-inch wide, 4.40 mm) for surface-mount assembly. No thermal pad to worry about — the push-pull outputs keep static dissipation low.","metaTitle":"CD74HC194PWR 74HC Bidirectional Shift Register, 2V-6V","metaDescription":"TI CD74HC194PWR 4-bit bidirectional universal shift register, 74HC family, 2V to 6V supply, -55°C to 125°C, 16-TSSOP.","metaKeywords":null},"attributes":{"series":"74HC","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"74HC","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Universal","Logic Type":"Register, Bidirectional","Output Type":"Push-Pull","Mounting Type":"Surface Mount","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2V ~ 6V","Number of Elements":"1","Operating Temperature":"-55°C ~ 125°C","Supplier Device Package":"16-TSSOP","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.68","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.68000","currency":"USD"},{"qty":10,"price":"$0.58000","currency":"USD"},{"qty":25,"price":"$0.54160","currency":"USD"},{"qty":100,"price":"$0.43330","currency":"USD"},{"qty":250,"price":"$0.40236","currency":"USD"},{"qty":500,"price":"$0.34048","currency":"USD"},{"qty":1000,"price":"$0.26309","currency":"USD"},{"qty":2000,"price":"$0.23988","currency":"USD"},{"qty":6000,"price":"$0.22440","currency":"USD"},{"qty":10000,"price":"$0.21900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/738688a40623d97c7db5ce1a7feb2067.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the function of CD74HC194PWR?","answer":"It is a 4-bit bidirectional universal shift register.
