74HCT595D,112

The 74HCT595D,112 is an 8-bit shift register with an output latch, designed for use in digital circuits. It is part of the 74HCT series, which is a high-speed CMOS logic family that is compatible with TTL (Transistor-Transistor Logic) levels. This device is manufactured by Nexperia, a well-known semiconductor company.

Key Features:

1. 8-Bit Shift Register: The 74HCT595D can store and shift 8 bits of data, making it suitable for applications that require serial-to-parallel data conversion.

2. Output Latch: Each of the 8 output pins can hold the last shifted data until it is updated, allowing for stable output even while new data is being shifted in.

3. Serial Input: The device accepts serial data input, which can be shifted into the register on the rising edge of a clock signal.

4. Parallel Output: The outputs can be accessed in parallel, allowing for easy interfacing with other digital components.

5. Control Pins: The device includes control pins such as:

   • Clock (SRCLK): This pin is used to shift the data into the register.
   • Latch Enable (RCLK): This pin is used to transfer the shifted data from the shift register to the output latch.
   • Output Enable (OE): This pin controls the output state, allowing the outputs to be enabled or disabled.

6. Power Supply: The 74HCT595D operates within a voltage range of 4.5V to 5.5V, making it suitable for standard 5V logic applications.

7. Temperature Range: The device is designed to operate in a wide temperature range, typically from -40°C to +125°C, making it suitable for various environmental conditions.

8. Package Type: The 74HCT595D,112 is available in a DIP (Dual In-line Package) form factor, which is easy to handle and solder onto PCBs. It may also be available in other package types such as TSSOP or SOIC.

9. Pin Configuration: The device typically has 16 pins, with specific pins designated for data input, clock, latch enable, output enable, and the 8 output pins.

Applications:

The 74HCT595D is commonly used in applications such as:

• LED driving and control
• Data storage and transfer in microcontroller projects
• Expanding the number of output pins in digital systems
• Serial communication interfaces

Electrical Characteristics:

• Propagation Delay: The typical propagation delay from the clock input to the output can be in the range of nanoseconds, allowing for high-speed operation.
• Input and Output Current: The device can typically source or sink a certain amount of current per output pin, making it suitable for driving small loads directly.

Conclusion:

The 74HCT595D,112 from Nexperia is a versatile and efficient 8-bit shift register that provides a simple solution for serial-to-parallel data conversion in digital circuits. Its compatibility with TTL logic levels, combined with its robust features and wide operating range, makes it a popular choice among engineers and hobbyists alike.
