TechnologiesThe U74HC165G-S16-R is an 8-bit parallel-out shift register with an output latch. This part is manufactured by Unisonic Technologies in their 74 Series and is a SOP-16 package that is RoHS compliant. It has an input shift register, clocked by a single clock pulse, that then feeds the output data into an 8-bit storage register. It has the capability of daisy chaining registers to increase the data width. It also has an active low enable pin and an active low output enable. The logic levels are both TTL and CMOS compatible, with a supply voltage range of 2V to 6V. It is a low-power CMOS logic device with a low-power version available.
