DM74LS191N Product Details

DM74LS191N Overview


This device is supplied in the 16-DIP (0.300, 7.62mm) package. The 1elements are connected by wires. Tubeis used to package it. Having been designed as a member of the 74LSseries, it is well suited to a variety of applications. Binary Counteris adopted as the logic type. It is recommended that the operating temperature be set to 0°C~70°C. The mounting type is Through Hole. When the supply voltage is set to [0], it is able to operate with greater reliability. There are 4bits stored in each element of the array. Under its base part number of [0], you will find additional related parts.
