The SN74LV164A is a low-voltage 8-bit serial-in parallel-out shift register specifically designed for low power consuming. This device has an “output enable” (OE) pin to enable or disable the output, making this an ideal choice for many different applications. The SN74LV164A is part of the TI Low Voltage (LV) logic family and, as such, is designed to be powered by a low voltage power supply, typically ranging from 2V to 5.5V.

The SN74LV164A is a versatile logic device for multiple applications, ranging from data replication and control, to digital interface communication, industrial automation, and automated test systems. In data replication, the shift register is used to transfer data from one source to multiple destinations.

In this case, the data is shifted in serial into the register, and then clocked out, which will send the same data to multiple destinations in parallel. In communication interface applications, the SN74LV164A serial-in parallel-out shift register can be used to receive data travelling on a serial communication line and convert it into parallel data for multi-bit manipulation. Industrial automation applications use the SN74LV164A serial-in parallel-out shift register as part of a programmable machinecontroller.

In automated test systems, the SN74LV164A is used to test boards and components to make sure they meet requirements. The SN74LV164A’s “output enable” pin enables the chip to be used in applications where it is necessary to control the output by an external signal.

The working principle of the SN74LV164A is based on the behavior of a chain of logic gates triggered by a clock signal. Each time a clock pulse is applied, the value at the serial data input is shifted one position, while the current content in the register is shifted one position higher. As the data is shifted, it will appear at the parallel outputs, depending on the state of the output enable pin.

When the output enable pin is in its high state, the parallel data will be stored and the next pulse of the clock signal will shift the stored data out of the register, while the serial data is loaded into the first stage of the register. When the output enable pin is in its low state, the output data will be in an undefined state. This feature can be used to disable the outputs when the inputs are dynamic.

In summary, the SN74LV164A is an 8-bit serial-in parallel-out shift register. The purpose of this logic device is to transfer data from one source to multiple destinations. The SN74LV164A is a low-voltage device, making it an ideal choice for many different applications. The SN74LV164A has an output enable pin that can be used to selectively enable or disable the outputs. This device is frequently used in data replication, communication interfaces, industrial automation, and automated test systems.
