The wide supply range from 3V to 18V makes it compatible with battery-operated 3V systems as well as traditional 5V, 12V, or 15V logic rails — a flexibility that 5V-only HC or HCT families cannot match. The 3V to 18V supply range is the headline spec for this part. That extended range matters for designs that must guarantee operation in engine-bay or cold-start environments. The 8-bit parallel-to-serial conversion with push-pull outputs means no external pull-up resistors on the output lines, saving two resistors per bit versus open-drain alternatives. The TSSOP footprint is standard and matches other 16-pin TSSOP logic devices, so a board layout for a 74HC165 or CD4014 in the same package can reuse the land pattern. The tape-and-reel or cut-tape options cover both prototype and production volumes. ## Lifecycle and supply status Active status and ROHS3 compliance indicate ongoing production support.","metaTitle":"CD4021BPWR 4000B Shift Register, 8-Stage, 16-TSSOP","metaDescription":"CD4021BPWR 8-bit static shift register from TI 4000B series. 3V to 18V supply, push-pull output, -55°C to 125°C.
