74HC595D

The 74HC595D is an 8-bit serial-in, parallel-out shift register with a storage register and a 3-state output. Manufactured by HTC Korea under the TAEJIN Tech brand, this integrated circuit is widely used in digital electronics for applications requiring the expansion of output pins, such as driving LEDs, controlling displays, or interfacing with other digital devices.

Key Features:

1. 8-Bit Shift Register: The 74HC595D can store and shift 8 bits of data, allowing for the serial input of data and parallel output. This is particularly useful for applications where the number of available microcontroller pins is limited.

2. Serial Data Input: The device accepts serial data input through a single data pin (DS), enabling the user to send data one bit at a time. This is ideal for applications where data needs to be transmitted over a single line.

3. Parallel Output: The outputs (Q0 to Q7) can be used to drive multiple devices simultaneously. Each output can be independently controlled, allowing for versatile applications in controlling LEDs, relays, or other digital devices.

4. Storage Register: The 74HC595D features a storage register that holds the data until it is transferred to the output. This allows for data to be shifted in while the outputs remain stable, providing a seamless transition when updating the output states.

5. 3-State Outputs: The outputs can be set to a high impedance state, allowing multiple devices to share the same output line without interference. This is particularly useful in bus systems where multiple devices may need to communicate over the same lines.

6. Clock and Latch Control: The device includes a clock input (SH_CP) that controls the shifting of data into the register. A latch input (ST_CP) is used to transfer the data from the shift register to the output register, allowing for controlled output updates.

7. Wide Operating Voltage Range: The 74HC595D operates over a voltage range of 2V to 6V, making it compatible with a variety of microcontrollers and logic levels.

8. High-Speed Operation: The device is capable of high-speed operation, with typical propagation delays in the nanosecond range, making it suitable for fast applications.

9. Low Power Consumption: The 74HC595D is designed for low power consumption, making it ideal for battery-operated devices and energy-efficient applications.

Package Information:

The 74HC595D is typically available in a 16-pin dual in-line package (DIP) or surface mount package (SOIC), making it easy to integrate into various circuit designs. The pin configuration includes power supply pins (Vcc and GND), data input, clock, latch, and output pins.

Applications:

• LED displays and lighting control
• Data communication interfaces
• Microcontroller output expansion
• Digital signal processing
• Robotics and automation systems

In summary, the 74HC595D from HTC Korea TAEJIN Tech is a versatile and efficient shift register that provides a practical solution for expanding output capabilities in digital circuits, making it a popular choice among engineers and hobbyists alike.
