The CD74HC595EG4 is an integrated circuit (IC) component that belongs to the CD74HC series of high-speed CMOS logic devices. It is a shift register with an output latching function, meaning it can store and display data in a cascaded manner. This IC is commonly used in applications where a large number of output pins are needed and limited input pins are available.
Key Features:
1. 8-Bit Serial-In, Parallel-Out Shift Register: The CD74HC595EG4 has an 8-bit serial input that accepts data in a serial format. The data is then shifted through the shift register and latched into the parallel outputs. This allows for easy expansion of output pins by cascading multiple ICs.
2. Serial Data Input and Output: The IC features a serial data input (SER) pin and a serial data output (QH') pin. The serial data input allows for daisy-chaining multiple ICs, while the serial data output provides a convenient way to connect additional shift registers.
3. Wide Operating Voltage Range: The CD74HC595EG4 operates within a wide voltage range, from 2V to 6V. This makes it compatible with a variety of power supply systems without the need for level shifting circuits.
4. High-Speed Operation: This IC is designed to operate at high speeds, making it suitable for applications requiring real-time data transfer. The typical propagation delay is around 13 ns, providing quick response times
