CD74HC21E Overview
The part is convenient to ship overseas because it is packed in a 14-DIP (0.300, 7.62mm). High reliability is provided by advanced packaging method Tube. AND Gate logic governs its operation. Voltage 2V~6V ensures the part's full functionality. Operation at a temperature around -55°C~125°C. Through Hole is the mounting position of the part. In both high and low states, output current is 5.2mA 5.2mA. The number 74HC refers to it. In total, there are 14 terminations. 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. Trying searching with 74HC21 will yield device variants. There are 14 pins injected into the part body. Many applications require the use of this logic device with its Through Hole mounting. For details about the functions of 14 pins, please refer to the datasheets. Inputs are limited to 4. Quiescent parts have 2μA current flowing through them. The logic device shown here is a typical Gates. In this part, the load capacitance is 50pF. To supply the device, a voltage of 2V must be applied. As soon as Vsup reaches 6V, the maximal supply voltage (Vsup) is reached. A device with an output current of 5.2mA is rated. 1 outputs are included in the device. By its 2 channels, the part provides high quality logic output.
