CD74HC139EE4 Overview
The encoder is embedded in PDIP-16 package.It is recommended to pack the encoder in Tube case.The total pins on the rotary encoders is 16.It is mounted by Through Hole.This encoder gets 16 pins on it.The maximum 125 °C ensures that the encoder reader runs stablily.This rotary encoder's minimum working temperature must not be less than -55 °C. The required minimum supply voltage should be larger than 2 V.6 V is reached as the maximum supply voltage (Vsup) of the encoder motor.This converter operates from a supply voltage of 2 V to 6 V.The total number of encoder bits is 4.It can work with the minimum supply voltage of 2 V.The maximum supply voltage across the converter is 6 V.It has 2 channels in total.The CD74HC139 series include this electrical quadrature encode.There are Dual on the encoder definition.
