Description

The SN74HC595DR is an 8-bit serial-in, parallel-out shift register with an output driver, designed for use in digital applications. It operates with a supply voltage range of 2V to 6V and is part of Texas Instruments' High-Speed CMOS logic family. The device allows for efficient data storage and transfer, making it ideal for applications requiring the expansion of I/O ports, such as LED displays, data communication, and sensor interfacing.
Key features include the ability to shift data in serial form while simultaneously providing a parallel output, cascaded connection for multiple devices, and a high-speed operation with a propagation delay as low as 3.5 ns at 5V. The SN74HC595DR also includes a latch for output control and a tri-state output for easy integration into larger logic systems.
Its versatility and efficient function make it a popular choice for microcontroller projects and various embedded systems.

Features

The SN74HC595DR is an 8-bit shift register with an integrated latch. Key features include:
1. 8-Bit Storage: It can store 8 bits of data.
2. Serial Input/Output: Supports serial data input (DS) and serial output (Q7’), enabling cascading of multiple devices.
3. Parallel Output: Provides 8 parallel outputs (Q0 to Q7) for easy interfacing with various applications.
4. Shift Register: Data can be shifted in and out on the clock edges (SHCP and STCP).
5. High-Speed Operation: Operates at high speeds, with a maximum clock frequency up to 100 MHz.
6. Wide Voltage Range: Compatible with a supply voltage range from 2V to 6V, suitable for both TTL and CMOS logic levels.
7. Low Power Consumption: Designed for low power operation, making it ideal for battery-powered applications.
8. Tri-State Outputs: Outputs can be set to high-impedance state, allowing multiple devices to connect to a common bus.
Overall, the SN74HC595DR is widely used in applications like LED control, data storage, and digital circuit interfacing.

Package

The SN74HC595DR is packaged in a 16-pin SOIC (Small Outline Integrated Circuit) format. It features a dual in-line configuration with a width of 7.5 mm and a height of 3.97 mm, suitable for surface mounting.

Pinout

The SN74HC595DR is an 8-bit shift register with an output latch. It has a total of 16 pins.
Pin Count and Functions:
1. Q0-Q7 (Pins 15-8): These are the eight output pins that provide the shifted data.
2. DS (Pin 14): Serial data input pin for shifting in new data.
3. SH_CP (Pin 11): Shift clock input; on the rising edge, data at DS is shifted into the register.
4. ST_CP (Pin 12): Storage register clock input; on the rising edge, the shifted data moves to the output latch.
5. MR (Pin 10): Master reset; active low input to reset all outputs to low.
6. OE (Pin 13): Output enable; active low input to enable the output drivers.
7. VCC (Pin 16): Supply voltage (typically +2V to +6V).
8. GND (Pin 8): Ground reference.
This device is commonly used in applications requiring data storage and control, such as LED driving and parallel output systems.
