HV57908PG-G

Logic - Shift Registers

The HV57908PG-G is a high-voltage parallel-out serial shift register (POSR) capable of controlling up to 8-bits of digital logic at high-voltage level, up to 26V. It is a right-moving unidirectional serial data shift register, designed for multiple-level logic, utilizing dynamic logic and overflow. The logic of the HV57908PG-G begins with the serial input register and ends with the parallel output register. The shift register can also be used as a 8-bit parallel-in serial-out shift register (PISO) on a common core.

The HV57908PG-G is capable of reliably operating at high-voltage levels up to 26V, making it suitable for industrial, consumer, and other high-voltage applications. The 1.8V supply voltage allows for easy integration into a wide range of digital systems.

The HV57908PG-G shifts all data serially, right-to-left, through the staging registers. The last bit shifted out of the input register is provided as the first bit to the output register, providing parallel output data. The data is shifted at one clock pulse per bit and the data propagation is independent of the clock pulse rate.

The HV57908PG-G provides the logic capability to form an 8-bit boundary scan cell master. Each cell master incorporates all the necessary gates, drivers and shift registers, uniting the logic elements into a single, programmable device.

The HV57908PG-G has a wide range of applications, from consumer electronics to industrial networking, switchgear, and sensor applications. With its ability to shift a high-voltage parallel data stream, the device is extremely flexible and can be used in a variety of applications, including for shift register based logic gates and data acquisition.

The HV57908PG-G can also be used as a high-voltage differential bus multiplexer, where data is shifted out of a serial input register to the parallel output register. This allows multiplexers to operate on data at various domains, while keeping the interface in the digital domain.

The size and simplicity of the HV57908PG-G make it ideal for a variety of applications, including high voltage digital logic and differential bus multiplexing. With the ability to program its logic and operate at both high-voltage and low-voltage levels, the HV57908PG-G can easily be integrated into a wide range of digital systems.
