Key Features
- Pin Expansion Made Simple: Control 8 outputs using only 3 microcontroller pins (Data, Clock, Latch), freeing GPIO for sensors and other peripherals.
- Unlimited Cascading: Daisy-chain multiple 74HC595 ICs together - control 16, 24, 32, or more outputs using the same 3 pins with no additional wiring complexity.
- Built-in Output Latches: Separate shift and storage registers prevent flickering or glitching - outputs update simultaneously only when you pulse the latch pin.
- Tri-State Output Enable: Dedicated OE pin lets you disable all outputs at once without losing stored data, perfect for multiplexing and power management.
- Wide Voltage Range (2V-6V): Works seamlessly with both 3.3V boards (ESP32, Raspberry Pi) and 5V boards (Arduino Uno, Mega) without level shifting.
- High Output Current: Each pin can source or sink up to 35 mA, enough to drive standard LEDs directly without additional transistor drivers.
- High-Speed CMOS Logic: Up to 25 MHz clock speed enables fast data throughput for demanding applications like LED matrix refreshing and display driving.
- Breadboard-Friendly DIP-16 Package: Standard through-hole package plugs directly into breadboards and perfboards for quick prototyping.
- Asynchronous Clear: SRCLR pin allows instant clearing of the shift register contents independent of the clock, useful for initialization and reset routines.
How It Works
The 74HC595 contains two internal 8-bit registers: a shift register and a storage register. Data is fed serially through the SER (Data) pin one bit at a time, clocked in by the SRCLK (Shift Clock) pin. Once all 8 bits are loaded, pulsing the RCLK (Latch Clock) pin transfers the data to the storage register, which drives the 8 parallel output pins (QA-QH) simultaneously. The QH' serial output carries overflow data to the next 74HC595 in a daisy chain. The active-low OE pin controls whether outputs are active or in a high-impedance state, and the active-low SRCLR pin resets the shift register.
