74HCT191D,652 Product Details

74HCT191D,652 Overview


In the 16-SOIC (0.154, 3.90mm Width)package, it is supplied. In order to configure it, it uses 16terminations. As a result of the supply voltage of 0, 5Vcan operate in a fully flexible manner. There are wires connecting 1elements. The total number of component pins is 16. Packaging is based on Tube. In this case, it appears as a member of the family [0]. Due to its membership in the 74HCTseries, it is suitable for a variety of applications. In this case, the logic type is set to [0]. -40°C~125°Cshould be set as the operating temperature. In this case, it is mounted with a Surface Mounttype. In the case of a supply voltage of [0], it operates more reliably. The array contains elements that store 4bits each. It is important to note that in regards to this electronic device, TCO OUTPUTis an extremely significant feature. Among its base part number [0], you will find additional parts that are related. In order to pack the product, BULK PACKis employed. From the voltage source, there is 5Vvoltage. There is 5.5V maximum supply voltage (Vsup) allowed.
