74AC191PC Product Details

74AC191PC Overview


The device is packaged in the 16-DIP (0.300, 7.62mm)type. An interconnection of 1elements is provided by wires. There is a package in the form of Tube. As part of the circuit, there are 16pins that connect other components. The Through Holeway is used to mount it. Due to the fact that it is a member of the 74ACseries, it has a wide range of applications. Logic type Binary Counter is adopted. Ideally, the operating temperature should be set to -40°C~85°C. This device is mounted in the Through Holeposition. As long as the supply voltage is set to [0], the device can operate with a greater degree of reliability. Further related parts may be found under the base part number 74AC191. The frequency of the system is 133MHz. There are 4 input lines that allow binary data to be input in the form of an on/off signal.
