SN74ALS191AD Overview


It is a device supplied in the 16-SOIC (0.154, 3.90mm Width) package. There are 16 terminations used for its configuration. 5Vis enabled to operate in an extremely flexible manner due to its supply voltage. A wire connects the 1elements. The number of all component pins is 16. As [0], it is packaged. In the circuit, there are 16pins that connect other parts. Using [0], it can be mounted. It emerges as a member of ALS family. Having been designed as a member of the 74ALSseries, it is well suited for use in a wide range of applications. Binary Counteris adopted as the logic type. In this case, the operating temperature should be set to 0°C~70°C. In this case, it is mounted with a Surface Mounttype. In the presence of the supply voltage of [0], it can operate more reliably. The array contains elements that store 4bits each. The result may be yeswhen expressing the result in Pbfree code. These electronic devices have many important features, and TCO OUTPUTis one of them. More related parts are available under its base part number 74ALS191. The voltage source generates 5Vvoltage. In order to operate, it requires a voltage of [0]. With a frequency of [0], it operates.
