What the CD4015BE is and where it fits
The Texas Instruments CD4015BE is a dual 4-bit static shift register from the 4000B series. It converts serial data to parallel output using push-pull stages, and operates across a 3V to 18V supply range.
Package and mounting
Through-hole 16-DIP (0.300" body, 7.62 mm pitch) is the standard breadboard and socket-friendly footprint. Use a 16-pin DIP socket for prototyping or field replacement; solder direct for production.
Lifecycle and sourcing
For dual-sourcing, the 4000B family includes several pin-compatible dual 4-bit shift registers from other manufacturers; verify the exact pinout against your layout.
