Description
SN74LS191NSR Overview
In the 16-SOIC (0.209, 5.30mm Width)package, it is supplied. There are 16terminations used for configuring it. This device is fully flexible due to the supply voltage of [0]. The device has 1terminations. There are 16pins on all components. Tape & Reel (TR)is the packaging method used for this package. Circuit components are connected with 16pins. It is mounted using the way of [0]. In this case, it emerges as a member of the LS family. The 74LSseries is well suited to a number of uses. Logic type Binary Counter is adopted. It is recommended to set the operating temperature to 0°C~70°C. Using a Surface Mountmounting type, it is mounted. In the case of a supply voltage of [0], it operates more reliably. The array contains elements that store 4bits each. Using the Pbfree code, the result may be yes. It is important to note that in regards to this electronic device, TCO OUTPUTis an extremely significant feature. More related parts are available under its base part number 74LS191. In order to package it, TRis employed. From the voltage source, there is 5Vvoltage. In order for it to operate, it requires a supply voltage of 5V . 25MHzis the frequency of operation.
