It accepts serial data on two inputs and shifts it through eight stages, presenting parallel data on eight push-pull outputs. Supply range is 4.75 V to 5.25 V, with a commercial temperature grade of 0°C to 70°C — suited for benchtop instruments, industrial controllers, and peripheral interfaces that stay indoors. The 14-SOIC package (3.90 mm body width) fits standard surface-mount assembly lines. Common applications include expanding digital outputs from a microcontroller, driving LED banks, or capturing parallel data from a serial source. The push-pull outputs eliminate the need for external pull-up resistors in most logic-level loads. ## Supply and temperature — what they mean for the BOM Supply range is 4.75 V to 5.25 V. If the rail droops under 4.75 V, the shift register may not hold valid logic states. The 0°C to 70°C commercial range covers temperature-controlled environments. ## Sourcing and lifecycle The SN74LS164DR is listed as Active and ROHS3 compliant. No end-of-life notice or last-time-buy schedule is in effect. This part is still a standard catalog item from Texas Instruments, and we source it through our independent distribution network — quoted to order against an RFQ with current availability and pricing confirmed at quote time.","metaTitle":"SN74LS164DR 8-bit shift register, 74LS, 14-SOIC","metaDescription":"SN74LS164DR 8-bit serial-to-parallel shift register, 74LS logic, 4.75V-5.25V, push-pull outputs, 0-70°C, 14-SOIC.
