Shift Registers

The SN74HC165DR is a high-performance, 8-bit parallel-in/parallel-out (PISO) shift register manufactured by Texas Instruments. It is designed to provide reliable and efficient data storage and transfer in various digital systems. Here's a brief description, features, and applications of the SN74HC165DR:

Description:

The SN74HC165DR is a member of the 74HCxx family of high-speed CMOS logic devices. It is an 8-bit shift register that can be used to store and transfer data in parallel format. The device features a PISO configuration, allowing data to be input and output simultaneously in parallel, making it suitable for a wide range of applications.

Features:

1. 8-bit shift register with PISO configuration
2. 3-state outputs for easy cascading or daisy-chaining
3. Active-low input and output enable (OE) control
4. Active-low serial input (SI) and serial output (SO) pins for easy interfacing with other shift registers or logic devices
5. Active-low parallel load (PL) control for parallel data loading
6. Active-low clear (CLR) input for resetting the shift register
7. Wide operating voltage range (2.0V to 6.0V)
8. High-speed performance with typical propagation delays of 3.5 ns (maximum 4.5 ns) at a 5.0V supply voltage
9. Low power consumption (typically 60 mW at 5.0V and 100 MHz)

Applications:

1. Data storage and transfer in digital systems
2. Parallel-to-serial and serial-to-parallel data conversion
3. Data buffering and synchronization in high-speed data communication systems
4. Address or data latching in memory interfaces
5. Data manipulation and control in microcontroller-based systems
6. Interfacing between parallel and serial devices
7. Digital signal processing and filtering applications
8. General-purpose logic and control functions in various electronic devices

The SN74HC165DR is available in various package options, including the SOIC (Small Outline Integrated Circuit) package, which provides a compact and efficient solution for space-constrained applications. Its high-speed performance, low power consumption, and versatile features make it suitable for a wide range of digital applications.
