SN74LS191D Overview
The device is packaged in the 16-SOIC (0.154, 3.90mm Width)type. In order to configure it, it uses 16terminations. The supply voltage of 5V enables it operate in a fully flexible way. The 1elements are connected by wires. A total of 16pins are available on all components. As [0], it is packaged. Circuit components are connected by 16pins. The Surface Mountway is used to mount it. It is a member of the family [0]. Due to the fact that it is a member of the 74LSseries, it has a wide range of applications. Binary Counteris used as the logic type. In this case, the operating temperature should be set to 0°C~70°C. Mounting type Surface Mountis used. Providing a supply voltage of 4.75V~5.25Vallows it to operate more reliably. The array consists of elements storing 4bits each. Based on Pbfree code, this may result in yes. These electronic devices have many important features, and TCO OUTPUTis one of them. You can find more related parts under its base part number of 74LS191. In this case, there is 5V voltage coming from the voltage source. The device requires a supply voltage of [0]. There is 25MHz frequency associated with it.
