74LS/HC165 74LS165 / 74HC165 / 74165 Dip 8-Bit Parallel-In/Serial-Out Shift Register

Product Description: 74LS/HC165 DIP 8-Bit Parallel-In/Serial-Out Shift Register

The 74LS/HC165 is an 8-bit parallel-in/serial-out shift register IC designed to convert parallel data inputs into a serial data output, making it ideal for data transfer and expansion applications. This IC features eight parallel data inputs and a single serial output, which can be used for efficient communication in systems with limited I/O pins. The 74LS/HC165 comes in both the LS (Low Power Schottky) and HC (High-Speed CMOS) versions, providing flexibility depending on the speed and power requirements of your application.

By shifting in 8 bits of data via a parallel input, the IC provides a compact solution for transferring multiple bits of data using a serial interface. It’s widely used in applications like microcontroller I/O expansion, interfacing with sensors or other devices, and digital signal processing systems where parallel-to-serial conversion is necessary. With a typical propagation delay of 11ns (LS version) or 7ns (HC version), it offers fast performance with low power consumption, depending on the variant chosen. The 74LS/HC165 operates with a supply voltage range of 4.5V to 5.5V, making it suitable for a variety of digital systems.

Features:

• 8-Bit Parallel Input: Allows for the simultaneous input of 8 bits of data, which are then converted to serial format for output, ideal for interfacing with microcontrollers or other systems.
• Serial Output: Outputs the parallel input data serially, providing an efficient way to transmit data using fewer wires or pins.
• Shift Register Operation: Data is shifted in one bit at a time with the clock input, making it ideal for sequential data processing or data transmission.
• Low Power Schottky (LS) and High-Speed CMOS (HC) Versions: The LS version is optimized for low power consumption, while the HC version offers higher-speed operation, providing flexibility for different application needs.
• Fast Propagation Delay: The LS version has a typical propagation delay of 11ns, and the HC version provides even faster performance with a delay of just 7ns.
• Output Enable: The IC includes an output enable (OE) pin, allowing for control of whether the output is active or in a high-impedance state.
• Wide Operating Voltage Range: Works with supply voltages from 4.5V to 5.5V, suitable for a broad range of logic systems.
• 14-pin DIP Package: The IC comes in a standard 14-pin Dual In-line Package (DIP), easy to integrate into breadboards or circuit boards.

Applications:

• I/O Expansion: The 74LS/HC165 is ideal for expanding the I/O capabilities of microcontrollers or digital systems by converting parallel inputs into serial data, thereby reducing the number of required I/O pins.
• Sensor Interface: Commonly used to interface with multiple sensors or devices that output parallel data, converting it into a serial format for processing by a microcontroller.
• Data Acquisition Systems: Perfect for applications in data logging and measurement systems, where multiple data inputs are converted into a single serial output for easy transmission or processing.
• Communication Systems: Used in serial communication systems to shift multiple bits of data over a single communication line, simplifying data transmission.
• Embedded Systems: Widely used in embedded systems to read data from external devices, process the data, and transmit it serially for further analysis or control.
• Digital Signal Processing: Found in DSP systems, where fast parallel-to-serial data conversion is required for signal manipulation or analysis.
