Toshiba CMOS 8-BIT Parallel/Serial-In Serial-Out Shift Register 5.5V 74VHC165FT

The Toshiba 74VHC165FT is a high-speed CMOS 8-bit parallel-in/serial-out shift register designed using advanced silicon gate C2MOS technology. It supports uni-directional data shifting and features gated clock input control. This device achieves performance comparable to Bipolar Schottky TTL ICs but with significantly lower power consumption.

Operating with a maximum supply voltage of 5.5 V, it is engineered for robust operation across a wide temperature range of -40°C to 125°C, making it ideal for applications in industrial, electronic, and commercial environments requiring reliable data serialization and timing functions.

The IC provides versatility with parallel-in or serial-in data loading synchronous to clock pulses, and includes safety features such as input protection circuits allowing 0 to 5.5 V input levels independent of supply voltage, and power-down protection on all inputs to prevent device destruction.

This shift register supports interfacing between 5 V and 3 V logic systems and is suitable for battery backup systems with dual power supplies. Its balanced propagation delays ensure steady timing performance necessary for precise digital circuit operations.

Fabricated with advanced silicon gate C2MOS technology. High speed with typical maximum frequency of 150 MHz at 5 V supply. Wide operating voltage range from 2.0 V to 5.5 V. Wide operating temperature range from -40°C to 125°C.

Input protection circuit for voltage tolerance and device longevity. Power-down protection on all inputs prevents damage during power loss. Compatible with 74 series 165 pin and function configuration.

This shift register is extensively used in digital circuits for data storage, transfer, and timing applications in industrial automation, communication systems, computing equipment, and other electronic devices requiring precise and fast serial data handling.
