4094 - Shift-And-Store Bus Register

The 4094 is an 8-stage CMOS shift-and-store bus register in a 16-pin DIP package, featuring serial-in, parallel-out functionality with three-state outputs. Operating on 3V to 15V, it supports data storage and transfer with high noise immunity and low power consumption. Ideal for cascading and bus interfacing, it performs reliably across -55°C to 125°C, compatible with TTL/CMOS systems.
