SN74ALS191ADR Overview


It is a device supplied in the 16-SOIC (0.154, 3.90mm Width) package. It is configured with 16terminations. Having a supply voltage of 5V enables to operate in a fully flexible manner. In wires, 1elements are connected. 16is the number of pins on all components. Tape & Reel (TR)is used to package it. As part of the circuit, there are 16pins that connect other components. To mount it, use the method of [0]. It emerges as a member of ALS family. With its 74ALSseries designation, it can be used for a range of applications. Logic type Binary Counter is adopted. A temperature of 0°C~70°Cshould be set for the operating environment. A mounting type of Surface Mountis adopted. As a result, the device operates more reliably when a supply voltage of 4.5V~5.5Vis applied. The array has 4elements. Pbfree code may produce the result yes. A major feature of this electronic device is its [0]. Further related parts can be found under its base part number 74ALS191. It is packed using [0]. As a result of the voltage source, there is 5V voltage. The device operates on a supply voltage of [0]. It operates with the frequency of 30MHz.
