M74HC191B1R Product Details

M74HC191B1R Overview


In the 16-DIP (0.300, 7.62mm)package, it is supplied. In order to configure it, it uses 16terminations. As a result of the supply voltage of 0, 4.5Vcan operate in a fully flexible manner. There are wires connecting 1elements. The total number of component pins is 16. Packaging is based on Tube. To connect the circuit's other components, there are 16pins. Using [0], it can be mounted. In this case, it appears as a member of the family [0]. Due to its membership in the 74HCseries, it is suitable for a variety of applications. In this case, the logic type is set to [0]. -55°C~125°Cshould be set as the operating temperature. In this case, it is mounted with a Through Holetype. In the case of a supply voltage of [0], it operates more reliably. In this device, there is information of 4bits. It is possible for the result to be yesin Pbfree code. It is important to note that in regards to this electronic device, TCO OUTPUTis an extremely significant feature. Among its base part number [0], you will find additional parts that are related. From the voltage source, there is 2/6Vvoltage. The device requires a supply voltage of [0]. In the case of the supply voltage (Vsup), it can be as low as 2V. There is 6V maximum supply voltage (Vsup) allowed. A total of 4input lines are used to input binary data.
