Description

The CD4094BE is a CMOS integrated circuit, primarily used as an 8-stage shift-and-store bus register. It is particularly useful in applications that require serial-in, parallel-out data conversion. Each stage in this IC consists of a D-type flip-flop with a parallel output, and the device supports cascading multiple units for larger data sequences.
Key features of the CD4094BE include low power consumption, high noise immunity, and a wide supply voltage range, typically from 3V to 15V. It is designed to operate within a broad temperature range, making it suitable for various environmental conditions.
The device includes a data input, clock input, strobe input, and an enable input, in addition to its eight parallel outputs. Its functionality is marked by its ability to shift data on the positive edge of the clock signal and store it in the output register upon the strobe input's activation.
The CD4094BE is widely used in digital applications such as data routing, driving LED displays, and other scenarios where serial-to-parallel conversion is required.
