Shipping overseas is convenient with the part packed in 14-DIP (0.300, 7.62mm). Advanced packaging method Tube is used to provide high reliability. As a result, it works on the principle of OR Gate. This part needs a voltage of 2V~6V to function properly. Around -55°C~125°C is the extended operating temperature. There is a hole in Through Hole for mounting the part. The high and low state of output current is 5.2mA 5.2mA. A 74HC series product. In total, there are 14 terminations. The part has 4 functions that significantly boost the user experience. I would like to point out that this chip is part of HC/UH. Use M74HC32 when searching for device variants. An injection of 14 pins is performed into the body of the part. This logic device is widely used in a wide variety of applications because it is Through Hole mounted. To find out what the 14 pins do, please refer to the datasheets. A 2 input is supported by the part. Parts in quiescent state carry 1μA current. A logic device of this type is a Gates. A load capacitance of 50pF is provided by the part. Devices require a voltage of 2V to be powered. In this case, Vsup reaches its maximum value. A device with an output current of 5.2mA is rated. This device includes 1 outputs. It is specified with the 5V volts voltage that the chip must be supplied with as its operating voltage. The operation of 4 gates is logical.
