SN74LS191DR Product Details
SN74LS191DR Overview
A 16-SOIC (0.154, 3.90mm Width)package is used for this device. Using 16terminations, it can be configured. 5Vis fully flexible due to its voltage supply. The device contains 1terminations. There are 16pins on all components. As a result, it is packaged in the way of a Tape & Reel (TR). Circuit components are connected with 16pins. The device is mounted in the direction of [0]. It is included in the LSfamily. With its 74LSseries designation, it can be used for a range of applications. It is decided to use the logic type [0]. It is recommended to set the operating temperature to 0°C~70°C. Using a Surface Mountmounting type, it is mounted. As a result, the device operates more reliably when a supply voltage of 4.75V~5.25Vis applied. It contains 4elements. Based on Pbfree code, this may result in yes. This electronic device is equipped with the following features [0]. It should be noted that there are more related parts under the 74LS191base part number. Its packaging is provided by [0]. In this case, 5Vvoltage is generated by the voltage source. The device operates on voltage [0]. Frequency 25MHzdetermines its operation.
