The TC74VHC164FK is an 8-bit serial-in, parallel-out shift register manufactured by Toshiba Semiconductor and Storage. This device is part of the VHC (Very High-Speed CMOS) family, offering high-speed operation and low power consumption. It is designed for applications requiring serial-to-parallel data conversion, such as display drivers, data acquisition systems, and control circuits.

Applications

• Display Drivers
• Data Acquisition Systems
• Control Circuits
• LED Matrix Control
• Digital Logic Circuits

Features

• High-Speed Operation: Propagation delay times are typically in the nanosecond range.
• Low Power Consumption: CMOS technology minimizes power dissipation.
• Serial-to-Parallel Conversion: Converts serial data input to parallel data output.
• 8-Bit Register: Stores 8 bits of data.
• Clear Input: Allows for asynchronous clearing of the register.

Benefits

• Fast Data Transfer: High-speed operation enables rapid data processing.
• Energy Efficiency: Low power consumption is ideal for battery-powered applications.
• Simplified Data Handling: Serial-to-parallel conversion simplifies data interface and control.

Additional Details

The TC74VHC164FK operates with a wide supply voltage range, typically from 2V to 5.5V, making it compatible with various logic levels. The VSSOP14 (Very Shrink Small Outline Package) offers a compact footprint for surface-mount assembly. The device features a serial data input (DSA and DSB), a clock input (CLK), and a clear input (/CLR). Data is shifted into the register on the positive-going edge of the clock signal. Asserting the /CLR input low asynchronously clears all bits in the register. The datasheet provides detailed timing specifications, such as setup and hold times, and propagation delays, which are crucial for proper operation in high-speed systems.
