What are the key features of CD4094BEG4?
- 8-bit serial-in, parallel-out shift register with integrated storage latch for two-stage data buffering
- Wide supply voltage range of 3 V to 18 V providing compatibility with both CMOS and TTL logic families
- 3-state parallel outputs with output-enable control simplifying shared bus and multiplexed output designs
What is CD4094BEG4 used for?
The CD4094BEG4 is commonly used in serial-to-parallel data expansion circuits, where a microcontroller drives the 3-wire serial interface to control 8 parallel output lines while sharing the bus with other devices. It also serves in LED display drivers, relay control boards, and industrial I/O expanders where the 16-pin DIP package suits through-hole prototyping and low-volume production environments operating across 3 V to 18 V supply rails.

Frequently Asked Questions
How many parallel output bits does the CD4094BEG4 provide, and what supply voltage range does it support?
The CD4094BEG4 provides 8 parallel output bits and operates across a supply voltage range of 3 V to 18 V. This wide range allows the device to work with 3.3 V, 5 V, and 12 V systems, making it versatile for mixed-voltage embedded and industrial designs.
For a relay-driver board design, how does the CD4094BEG4 reduce GPIO pin count on a microcontroller?
By using a 3-wire serial interface (clock, data, strobe), the CD4094BEG4 expands 3 microcontroller GPIO pins into 8 parallel outputs. This saves 5 GPIO pins compared to direct parallel connections, freeing them for other peripherals, while the 3-state output enable avoids bus contention when multiple expanders share one output bus.
What package does the CD4094BEG4 use, and how does it benefit prototyping workflows?
The CD4094BEG4 comes in a 16-pin dual-in-line (DIP) package with 2.54 mm pin pitch, which fits standard breadboards and through-hole perfboards directly. This eliminates adapter boards during prototyping, reducing development time for low-speed serial-to-parallel expansion circuits.
When is the CD4094BEG4 a suitable alternative to the 74HC595 shift register?
The CD4094BEG4 is preferred when the system supply voltage exceeds the 74HC595's 6 V maximum, as it operates up to 18 V and drives higher-voltage loads directly. For 12 V industrial relay boards or 9 V battery-powered controllers, the CD4094BEG4 eliminates a level-shifter stage that would be required with the 74HC595.
