M74HC21B1R Overview
This high-reliability packaging method uses advanced packaging methods Tube. A significant improvement in the user experience can be achieved by the part since it has 2 functions. There is a chip in this package that is a part of HC/UH. An injection of 14 pins is performed into the body of the part. It is widely used in a variety of applications due to its Through Hole mounting. To find out what the 14 pins do, please refer to the datasheets. As of 4, the part supports 4 inputs. Parts that are quiescent have 1 µA current flowing through them. It is a typical Gates logic device. Supplying the device requires a minimum voltage of 2 V. In this case, Vsup reaches its maximum value. There is a method TUBE in it that is designed for the industry. Datasheets indicate that this part requires 2/6 V power supply. As part of the device, there are 1 outputs. An operation based on gates of 2. When the device is operating in a temperature environment higher than that of 125 °C, it should be turned off. It is estimated that the minimal operating temperature of the part is -55 °C. It is recommended that users do not supply the device with voltages greater than 6 V under normalcircumstances. The lowest voltage the part should receive is 2 V. This part performs better with 4 input lines. There are several uses for this AND GATE logic device.
