What are the key features of CD74HC4094PWR?
- 8-stage serial-in parallel-out shift register with storage latches and 3-state output control for bus-oriented designs
- High-speed HC CMOS operation up to 20 MHz clock frequency with 50 pF load capacitance compatibility
- Wide supply voltage range of 2 V to 6 V in compact 16-pin TSSOP package for low-power serial-to-parallel conversion
What is CD74HC4094PWR used for?
The CD74HC4094PWR is used to expand microcontroller output ports by converting a 2-wire serial stream into 8 parallel outputs, enabling control of LED arrays, relay banks, and seven-segment displays from a single SPI bus. Its 3-state output capability allows multiple devices to share the same parallel bus, making it suitable for daisy-chained display driver and I/O expander applications. Engineers also deploy it in industrial automation panels and keypad matrix drivers where minimal I/O pin usage is critical.

Frequently Asked Questions
What is the maximum clock frequency for CD74HC4094PWR and what load capacitance does it tolerate?
The CD74HC4094PWR operates at a maximum shift-register clock frequency of 20 MHz with a specified load capacitance of 50 pF, making it suitable for moderate-speed serial-to-parallel conversion in 5 V and 3.3 V microcontroller systems.
How many output stages does CD74HC4094PWR provide, and what output sink current is available per pin?
CD74HC4094PWR provides 8 parallel output stages, each capable of sinking up to 5.2 mA (IOL), sufficient to drive LEDs through current-limiting resistors or low-current relay coils without additional buffer transistors in typical 5 V designs.
Can multiple CD74HC4094PWR devices be daisy-chained for wider parallel output expansion?
Yes, the CD74HC4094PWR includes a serial data output pin (QS) that passes the last bit in the shift register to the next device's serial input, enabling seamless daisy-chain expansion to 16, 24, or more parallel outputs using only 2 wires from the host microcontroller.
How does CD74HC4094PWR differ from a 74HC595 shift register in terms of output control?
Unlike the 74HC595, the CD74HC4094PWR features separate output enable and strobe controls allowing 3-state bus sharing; both devices shift 8 bits at up to 20 MHz, but CD74HC4094PWR suits bus-multiplexed architectures needing high-Z output states, while 74HC595 is simpler for dedicated LED or relay drivers.
