What is CD74HC597M96 used for?
The CD74HC597M96 is used for serial data expansion in microcontroller systems where multiple digital inputs must be read over a 3-wire SPI-compatible bus, reducing pin count. It is also applied in keyboard matrix scanning, industrial control panels, and data acquisition front ends where parallel sensor data needs serial transmission at clock rates up to 20 MHz.

Frequently Asked Questions
What is the maximum clock frequency of CD74HC597M96, and which supply voltage maximizes its speed?
The CD74HC597M96 supports a maximum shift-register clock frequency of 20 MHz at a 6 V supply; at 3.3 V the speed is de-rated to approximately 8 MHz, which is still sufficient for most SPI-based I/O expansion applications in embedded systems.
How does the input storage latch in CD74HC597M96 benefit designs that sample noisy parallel signals?
The 8-bit input storage latch captures parallel data at a chosen moment via a separate latch-enable pin, isolating the shift register from live signal changes during serial shifting; this prevents bit errors when sampling bouncing switch signals or asynchronous sensor outputs in a 5 V industrial system.
Can CD74HC597M96 be cascaded to handle more than 8 inputs, and what is the wiring approach?
Yes, multiple CD74HC597M96 devices can be cascaded in series by connecting the serial output (QH) of one device to the serial input (DS) of the next, allowing 16, 24, or 32 parallel inputs to be read over a single 3-wire SPI bus at up to 20 MHz clock rate with the same host-side code.
Is CD74HC597M96 compatible with 3.3 V microcontrollers, and does it need a level shifter?
The CD74HC597M96 operates from 2 V to 6 V, so when powered at 3.3 V it is fully compatible with 3.3 V microcontroller logic levels without a level shifter; if the device is powered at 5 V while the MCU operates at 3.3 V, a level translator is required to protect the MCU's input pins.
