SN74LV164RGYR: 8-Bit Parallel-Out Serial Shift Registers

The SN74LV164RGYR is a high-performance, 8-bit serial shift register designed by Texas Instruments, a leader in semiconductor solutions. This device is part of the SN74LV family, which is renowned for its low-voltage operation and high-speed capabilities. The SN74LV164RGYR is specifically engineered to handle serial-to-parallel data conversion with high efficiency and reliability.

Constructed with an advanced CMOS technology, the SN74LV164RGYR operates at a voltage range of 2 V to 5.5 V, making it suitable for a wide array of applications that require low power consumption. This versatility allows it to be integrated into both battery-powered and traditional wired electronic systems. The device's 8-bit parallel-out shift register function is essential for expanding the data handling capacity of microprocessors and microcontrollers with minimal pin count increase.

The SN74LV164RGYR features two serial data inputs (A and B), eight parallel outputs (Q0 to Q7), a clock input (CLK), and a clear input (CLR). The clear input allows for the synchronous reset of the output registers, providing designers with the ability to quickly initialize the system during power-up or after an error. The clock input is used to sequentially shift the data present at the A or B inputs into the register on the rising edge of the clock pulse.

Thanks to its compact 14-pin VQFN (RGY) package, the SN74LV164RGYR is an excellent choice for space-constrained applications. It is also characterized by its high-speed operation, with typical shift frequencies reaching up to 50 MHz, ensuring rapid data processing and transfer. This makes the device particularly well-suited for digital signal processing, data acquisition systems, and communication interfaces where speed is critical.

For designers and engineers looking for a reliable and efficient way to expand the output capabilities of their digital systems without incurring significant power or space penalties, the SN74LV164RGYR offers a robust solution. Its compatibility with 5V TTL logic levels and the ability to drive up to 15 LSTTL loads further ensure its easy integration into a wide range of digital environments.
