CD74HCT237EE4 Overview
In total, the rotary encoders has 16 pins in total.Ideally, 4.5 V should be higher than the required minimum supply voltage.There is a maximum supply voltage (Vsup) of a encoder motor where 5.5 V is reached.This rotary encoder can also be used in order to establish ADDRESS LATCHES; 3 ENABLE INPUTS when using it.
