What is CD74HC4094NSR used for?
The CD74HC4094NSR is widely used for expanding the parallel output capability of microcontrollers by converting a serial data stream from an SPI or bit-bang interface into 8 simultaneous parallel outputs, reducing GPIO pin usage. It is commonly applied in LED bar graph drivers, relay control arrays, LCD segment controllers, and multi-channel digital-to-analog output applications where latched parallel data must be updated synchronously. The 3-state output feature also makes it suitable for shared data bus architectures in programmable logic and embedded system designs.

Frequently Asked Questions
What is the function of the CD74HC4094NSR?
The CD74HC4094NSR is an 8-stage serial-in parallel-out shift register with output storage latches. It shifts serial input data on each clock edge, stores it in the register, and transfers it to the 8 parallel outputs on a strobe signal, enabling synchronous parallel output updates without output glitches during shifting.
What is the maximum clock frequency of the CD74HC4094NSR?
The CD74HC4094NSR supports a maximum clock frequency of 20 MHz at nominal supply voltage, providing sufficient speed for most serial-to-parallel data conversion applications. This makes it suitable for SPI-driven output expanders and clocked shift register chains in embedded system designs.
What are the 3-state outputs used for on the CD74HC4094NSR?
The 3-state outputs on the CD74HC4094NSR allow all parallel outputs to be placed in a high-impedance state when the output enable pin is deasserted. This is essential for connecting multiple devices to a shared data bus, as it prevents bus contention when other devices are driving the same lines.
Can multiple CD74HC4094NSR devices be cascaded?
Yes, the CD74HC4094NSR provides a serial output (QS) pin that feeds the shifted data to the next device in a chain. By cascading multiple ICs, designers can create 16-bit, 24-bit, or wider parallel output expanders using a single serial data line, significantly expanding GPIO capability with minimal interface pins.
What is the supply voltage range and package for the CD74HC4094NSR?
The CD74HC4094NSR operates from 2V to 6V supply voltage and is housed in a 16-pin SOIC package (JESD-30 code R-PDSO-G16). The small outline package supports automated SMT assembly, and the wide voltage range enables use in both 3.3V and 5V digital systems across industrial, consumer, and embedded electronics applications.
