74HC595D,118

The 74HC595D,118 is a high-speed CMOS (Complementary Metal-Oxide-Semiconductor) shift register with an 8-bit output, produced by Nexperia. It is part of the 74HC family of logic devices, which are known for their high-speed operation and low power consumption. Here’s a detailed description of its features and specifications:

General Description:

• Functionality: The 74HC595 is an 8-bit serial-in, parallel-out shift register. It allows for the serial input of data, which can then be shifted out in parallel format. This makes it ideal for applications where you need to control multiple outputs with minimal pin usage on a microcontroller.
• Data Storage: It has an 8-bit storage register that holds the data until it is shifted out to the output pins.
• Output Control: The device features a tri-state output, meaning that the outputs can be enabled or disabled, allowing for multiple devices to share the same output lines without interference.

Key Features:

• Number of Bits: 8 bits (1 byte) of data can be shifted in and out.
• Shift Register Type: Serial-in, parallel-out (SIPO).
• Clock Input: The device includes a clock input (SRCLK) that controls the timing of data shifting.
• Latch Functionality: It has a latch (RCLK) that allows the stored data to be outputted at the same time, regardless of when the data was shifted in.
• Output Enable: An output enable pin (OE) allows for control over whether the outputs are active or in a high-impedance state.
• Power Supply Voltage: Typically operates at a supply voltage (Vcc) of 2V to 6V, making it compatible with a wide range of digital circuits.
• Propagation Delay: The device has a low propagation delay, typically around 15 ns at 5V, allowing for fast data processing.
• Temperature Range: It operates over a temperature range of -40°C to +125°C, making it suitable for various environmental conditions.

Pin Configuration:

The 74HC595D,118 comes in a standard 16-pin Dual In-line Package (DIP) or surface mount package. The pin configuration includes:

• Serial Data Input (DS): The pin where the serial data is fed into the shift register.
• Clock Input (SRCLK): The pin that receives the clock signal to shift the data.
• Latch Clock Input (RCLK): The pin that latches the data from the shift register to the output.
• Output Enable (OE): The pin that controls the output state.
• Parallel Outputs (Q0 to Q7): The 8 output pins that provide the parallel data.

Applications:

The 74HC595D,118 is widely used in various applications, including:

• LED Control: Driving multiple LEDs with fewer microcontroller pins.
• Data Communication: Expanding the number of outputs in microcontroller-based systems.
• Display Control: Used in multiplexed display systems.
• Sensor Data Handling: Collecting data from multiple sensors and sending it to a microcontroller.

Conclusion:

The 74HC595D,118 from Nexperia is a versatile and efficient shift register that simplifies the process of controlling multiple outputs in digital circuits. Its combination of high-speed operation, low power consumption, and ease of use makes it a popular choice among engineers and hobbyists alike.
