It can shift data left or right, load parallel data, or hold its state — all controlled by two mode-select pins. Typical applications include serial-to-parallel data conversion, digital delay lines, and state registers in 5V TTL-based control systems, industrial logic controllers, and legacy test equipment. ## Lifecycle and sourcing reality The SN74LS194AN carries an Active lifecycle status and is ROHS3 compliant. For a BOM line that needs a 5V bidirectional shift register in a DIP package, this part is a straightforward, available choice.","metaTitle":"SN74LS194AN 74LS Bidirectional Shift Register, 16-DIP","metaDescription":"SN74LS194AN 4-bit bidirectional universal shift register from TI 74LS series. 5V supply, push-pull output, 16-DIP through-hole.","metaKeywords":null},"attributes":{"series":"74LS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"74LS","Package":"Tube","Function":"Universal","Logic Type":"Register, Bidirectional","Output Type":"Push-Pull","Mounting Type":"Through Hole","Package / Case":"16-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Number of Elements":"1","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"16-PDIP","Number of Bits per Element":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.96","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.96000","currency":"USD"},{"qty":10,"price":"$1.75800","currency":"USD"},{"qty":25,"price":"$1.65880","currency":"USD"},{"qty":100,"price":"$1.41340","currency":"USD"},{"qty":250,"price":"$1.32712","currency":"USD"},{"qty":500,"price":"$1.16124","currency":"USD"},{"qty":1000,"price":"$0.96216","currency":"USD"},{"qty":2500,"price":"$0.93900","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/aaa3cb61761e1072010e99cfac6f339b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the function of the SN74LS194AN?","answer":"It is a 4-bit bidirectional universal shift register.
