ON Semiconductor 74VHC164N 8-Bit Serial-In Parallel-Out Shift Register

The ON Semiconductor 74VHC164N is a high-speed Si-gate CMOS device that is designed to handle the demands of high-performance, high-speed systems. This integrated circuit is an 8-bit serial-in, parallel-out shift register that allows for the conversion of serial data into parallel output format, making it an essential component for expanding the data handling capacity of a microcontroller or processor with minimal pin count usage.

The 74VHC164N is characterized by its wide operating voltage range of 2V to 5.5V. This feature makes it compatible with TTL levels and provides the flexibility to work within various system voltage requirements. It is capable of shifting at a speed of 175 MHz when operating at 5V, which makes it suitable for high-speed data processing applications.

Each of the eight output pins can sink 8 mA at 5V, allowing direct drive of LEDs and other low-power display elements. Furthermore, the device features a high noise immunity characteristic of CMOS devices and provides a typical hysteresis level of 1V at Vcc = 5V, which enhances its performance in noisy environments.

The 74VHC164N comes in a narrow 14-pin DIP (Dual In-line Package), which is widely used and easily integrated into various circuit boards. The pin configuration includes two serial data inputs (A and B), eight parallel data outputs (Q0 to Q7), a clock input (CP), and a clear input (MR) that resets the internal registers to the low state when taken high.

Applications for the 74VHC164N are diverse and include digital signal processing, data transfer, control systems, and any application that requires the conversion of serial data to parallel data. Its high-speed operation, combined with the ability to drive multiple outputs, makes it an ideal choice for expanding the output capabilities of microcontrollers, for LED displays, and for use in serial-to-parallel data conversion tasks.

ON Semiconductor ensures that the 74VHC164N meets the strict standards for industrial-grade components, providing reliability and performance for critical applications. With its robust design and versatility, the 74VHC164N is a valuable tool for designers looking to enhance their digital systems.
