What are the key features of CD74HC597EE4?
- 8-stage parallel-in serial-out (PISO) operation with a wide 2 V to 6 V supply range for mixed-voltage systems
- Up to 20 MHz clock frequency with 50 pF load capacitance, enabling fast serial data transfer
- SISO (serial-in serial-out) operation also available, adding flexibility for daisy-chaining multiple shift registers
What is CD74HC597EE4 used for?
The CD74HC597EE4 is used to expand microcontroller I/O by converting parallel data from buttons, switches, or sensors into a serial bitstream over SPI or similar buses. Its wide 2 V to 6 V supply range makes it compatible with both 3.3 V and 5 V logic systems in industrial control panels, keyboard scanners, and test equipment. Engineers also use it in data-logging hardware where multiple parallel signals must be serialized before transmission.

Frequently Asked Questions
What supply voltage range does the CD74HC597EE4 support, and how does that affect system design?
The CD74HC597EE4 operates across a 2 V to 6 V supply range, making it directly compatible with both 3.3 V microcontrollers and 5 V legacy logic without level-shifting circuitry. This flexibility simplifies mixed-voltage board designs in industrial or consumer products.
How fast can the CD74HC597EE4 shift data and what load does it assume?
The device supports a maximum clock frequency of 20 MHz with a 50 pF load capacitance. At 20 MHz, it can transfer all 8 parallel input bits as a serial word in as little as 400 ns, which is fast enough for real-time sensor polling in most embedded systems.
In what scenarios would a designer daisy-chain multiple CD74HC597EE4 devices?
By connecting the serial output of one CD74HC597EE4 to the serial input of the next, designers can read 16, 24, or 32 parallel inputs using only 3 microcontroller pins (CLK, LATCH, DATA). This approach is common in keyboard scanners, switch-matrix expanders, and industrial I/O modules requiring more than 8 parallel inputs.
