Product Overview

SN74HC595N is a high-performance 8-bit shift register launched by Texas Instruments (TI), featuring 16-PDIP package and core function of serial-in parallel-out conversion. Controlled by independent shift clock and storage clock, the device supports multi-chip cascading and realizes bus multiplexing with 3-state output characteristic, widely applicable to embedded systems, LED driving and industrial control scenarios. As a classic model of HC series, SN74HC595N becomes the preferred solution in electronic design for its low power consumption, wide voltage compatibility and high driving capability.

Key Features

• Wide Voltage Compatibility: Operating voltage range 2V-6V, adapting to different logic level systems and compatible with 3.3V and 5V mainstream control circuits.
• Low Power & High Efficiency: Maximum supply current only 80µA, typical propagation delay 13ns, balancing power consumption and speed requirements.
• High Driving Capability: Output drive current up to ±6mA at 5V, capable of directly driving 15 LSTTL loads without additional amplifier circuits.
• Flexible Cascading: Multi-chip series connection via serial output (QH’), enabling unlimited expansion of output ports in theory, suitable for large LED matrices and other scenarios.
• 3-State Output: Entering high-impedance state under the control of output enable (OE) pin, supporting multi-device shared data bus and reducing system wiring complexity.

Technical Specifications

Typical Applications

• LED Display Driving: In LED dot matrices or nixie tube arrays, SN74HC595N controls 8-channel outputs via 3 MCU pins. After cascading, it can drive displays with hundreds of pixels, significantly reducing the occupation of main control pins, commonly used in Arduino creative projects and small billboards.
• MCU Interface Expansion: When MCU pin resources (such as STM32, ESP32) are insufficient, the serial-parallel conversion function of SN74HC595N can expand a small number of GPIOs into multi-channel digital outputs to control peripherals like relays and solenoid valves.
• Consumer Electronics Control: In audio equipment and toy circuits, SN74HC595N realizes key scanning, light switching and other functions, and its low-power characteristic extends the battery life of portable devices.
• Industrial Automation: In sensor data acquisition modules, it realizes multi-channel signal switching with 3-state output, and the wide temperature tolerance of -40°C adapts to harsh factory environments.
• Educational Experiment Platform: With easy-to-solder package and clear logic, SN74HC595N becomes the core demonstration device for "shift register principle" in digital circuit courses, suitable for educational scenarios.
