The TC74VHC165FT(EL) is a high-speed CMOS 8-Bit Parallel-In Serial-Out Shift Register manufactured by Toshiba Semiconductor and Storage. This device is designed for high-speed parallel-to-serial data conversion in a variety of digital systems. It is fabricated with silicon gate CMOS technology, achieving high-speed operation while maintaining low power consumption.

Applications:

• Parallel-to-serial data conversion
• Remote data transmission
• Keyboard encoders
• Data acquisition systems
• Microprocessor interface

Features:

• High-speed operation: fMAX = 130 MHz (typ.) at VCC = 5 V
• 8-bit parallel inputs
• Serial data output
• Synchronous parallel loading
• Asynchronous clear input
• Low power dissipation: ICC = 4 μA (max) at VCC = 5 V
• Wide operating voltage range: VCC = 2 V to 5.5 V

Benefits:

• Fast data transfer rates due to high-speed operation.
• Efficient parallel-to-serial conversion, simplifying data transmission.
• Synchronous parallel loading ensures reliable data capture.
• Asynchronous clear allows for immediate resetting of the register.
• Low power consumption reduces energy usage and heat generation.
• Versatile application range due to the wide operating voltage range.

Additional Details:

The TC74VHC165FT(EL) is supplied in a TSSOP package. Data is loaded into the register in parallel when the Shift/Load (SH/LD) input is LOW. When SH/LD is HIGH, data is shifted serially on the positive-going clock transition. A LOW level on the Clear (CLR) input resets the register. The device operates over a wide temperature range, making it suitable for various industrial and commercial applications. The inputs are equipped with protection circuits against static discharge.
