CD74HC191E Overview


The device is packaged in the 16-DIP (0.300, 7.62mm)type. Using 16terminations, it can be configured. As a result of the supply voltage of 0, 4.5Vcan operate in a fully flexible manner. In wires, 1elements are connected. All component pins are equal to 16. Packaging is based on Tube. To connect the circuit's other components, there are 16pins. The way of Through Hole is used to mount it. In this case, it appears as a member of the HC/UH family. As a member of 74HC series, it is well suited for various applications. It is decided to use the logic type [0]. Ideally, the operating temperature should be set to -55°C~125°C. This device is mounted in the Through Holeposition. Providing a voltage of 2V~6Vensures higher reliability of operation. It contains 4elements. In regard to this electronic device, RCO OUTPUTare essential features. Under its base part number of [0], you will find additional related parts. There is a minimum supply voltage (Vsup) of 2V volts. In this case, the frequency is 35MHz Hz. There is 6V maximum supply voltage (Vsup) allowed. Its foundation is configured through the 2channels.
