The SN74HC164PWT is a high-performance, 8-bit serial-in, parallel-out shift register designed and manufactured by Texas Instruments. This integrated circuit is part of the 'HC' family, which indicates that it is fabricated with silicon-gate CMOS technology, offering a perfect balance between speed and power consumption.

Key Features

• Wide Operating Voltage Range: The device can function with a supply voltage ranging from 2V to 6V, making it versatile for various digital logic applications.
• High-Current Outputs: It can drive up to 5.2 mA at the output, allowing it to directly interface with numerous components such as LEDs and other high-drive elements.
• Shift Register: The 8-bit serial-in, parallel-out shift register allows for serial data input and converts it into parallel data output, which is essential for expanding the number of I/Os in microcontroller-based systems.
• Direct Clear Function: An asynchronous clear input (CLR) is provided for initializing the shift register, ensuring the outputs are in a known state upon startup or reset.
• Edge-Triggered Clocking: The device uses a positive-edge triggered clock (CLK), which ensures reliable and predictable data entry into the register.
