CD4094 8-Stage Shift-and-Store Register IC DIP-16 (CD4094 DIP IC)
The CD4094 Shift-and-Store Register IC is a CMOS 8-stage serial shift register with a storage (latch) register and 3-state outputs, designed for efficient data storage and transfer in digital systems. It allows serial data input and provides parallel outputs, making it ideal for expanding output pins in microcontroller-based applications.
This IC features separate shift and storage registers, enabling data to be shifted in serially and then latched simultaneously to the outputs. With its 3-state output capability, the CD4094 is well-suited for bus-oriented systems and multiplexed display applications.
It is widely used in LED driving, display systems, data storage, and microcontroller interfacing, especially in Arduino and embedded electronics projects where output expansion and controlled data transfer are required.
