74HC595 Shift Register

74HC595 Shift Register The 74HC595 is an 8-bit serial-in, parallel-out (SIPO) shift register used to expand the number of digital output pins available from a microcontroller. It allows a microcontroller such as Arduino or ESP32 to control up to 8 output devices using only a few control pins. Data is sent to the 74HC595 serially, one bit at a time, and then stored and presented simultaneously on its eight parallel output pins (Q0–Q7). Multiple 74HC595 ICs can also be cascaded to control a larger number of outputs. Key Features: Type: 8-bit serial-in, parallel-out shift register Outputs: 8 digital outputs Operating voltage: Typically 2–6 V Control pins: Data, clock, and latch Cascading: Multiple ICs can be connected together Applications: LED control, 7-segment displays, LCD interfaces, digital output expansion, and embedded systems Working Principle: The microcontroller sends binary data through the SER (serial data) pin while the SRCLK (clock) pin shifts each bit into the register. A pulse on the RCLK (latch) pin transfers the stored data to the eight output pins. This makes it possible to control many outputs while using only a small number of microcontroller pins.Reasonable price in Bangladesh
