SN74LS191DE4 Overview
This device is supplied in the 16-SOIC (0.154, 3.90mm Width) package. The configuration of this device is based on 16terminations. The supply voltage of 5V enables it operate in a fully flexible way. The device contains 1terminations. The total number of component pins is 16. As a result, it is packaged in the way of a Tube. A circuit is connected to other components by 16pins. Using [0], it can be mounted. The LSfamily is derived from it. This device is a member of the 74LSseries and is well suited for a wide range of applications. The logic type of Binary Counter is adopted. 0°C~70°Cshould be the operating temperature. In this case, it is mounted with a Surface Mounttype. In the case of a supply voltage of [0], it operates more reliably. The array consists of elements storing 4bits each. Pbfree code may produce the result yes. In regard to this electronic device, TCO OUTPUTare essential features. Among its base part number [0], you will find additional parts that are related. The voltage source generates 5Vvoltage. In order for it to operate, it requires a supply voltage of 5.25V . It operates at a frequency of 25MHz Hz.
