CD74HC191MT Overview


A device of this type is supplied in a package of type [0]. It is configured with 16terminations. The supply voltage of 4.5V permits it to operate with full flexibility. There are wires connecting 1elements. 16is the number of pins on all components. Packaging is based on Tape & Reel (TR). To connect the circuit's other components, there are 16pins. The way of Surface Mount is used to mount it. It emerges as a member of HC/UH family. The 74HCseries offers a wide range of applications due to its versatility. Logic type Binary Counter is adopted. A temperature of -55°C~125°Cshould be set for the operating environment. In this case, it is mounted with a Surface Mounttype. Providing a voltage of 2V~6Vensures higher reliability of operation. Each element in the array stores 4 bits. The result may be yeswhen expressing the result in Pbfree code. When it comes to this electronic device, RCO OUTPUT are much important features. Its base part number, [0], contains more related parts. The packing of the product is carried out by [0]. As a result of the voltage source, there is 2/6V voltage. As low as 2V Vsup is the minimum supply voltage. Frequency 35MHzdetermines its operation. Up to a maximum voltage of 6Vcan be supplied (Vsup).
