Multiple SN74LVC1G175B-EP devices can be used in tandem to create a shift register of arbitrary length. In this example, we use four SN74LVC1G175B-EP devices to form a 4-bit serial shift register. By connecting all CLK inputs to a common clock pulse and tying each output of one device to the next, we can store and load 4-bit values on demand. We demonstrate loading the 4 bit value 1101 into memory by setting Serial Input Data to each desired memory bit, and by sending a clock pulse for each bit, we sequentially move all stored bits from left to right
