The CD74HCT4511E: Supply range is 4.5 V to 5.5 V. Quiescent current sits at 8 µA. The through-hole 16-DIP package (0.300" body width, 7.62 mm pitch) is a legacy footprint. No SMD option exists in this order code, so plan for hand-assembly or wave-solder if your line is surface-mount only.
The CD74HCT4511E is Active and ROHS3 compliant per TI's current lifecycle status. No end-of-life or last-time-buy has been announced.
The CD74HCT4511E and CD4511BE are pin-compatible and functionally identical BCD-to-7-segment drivers in 16-DIP. The HCT variant has TTL-compatible input thresholds; the CD4511BE uses CMOS-level inputs. Choose the HCT if your upstream logic is 5 V TTL or HCT, the CD4511BE if it's pure CMOS.
