SN74HC21N Overview
This part is conveniently packaged in 14-DIP (0.300, 7.62mm), making it easy to ship abroad. A high level of reliability can be achieved through the use of an advanced packaging method Tube. According to AND Gate logic, the algorithm works. Voltage 2V~6V ensures the part's full functionality. Operating temperature extended to -40°C~85°C. Part Through Hole is mounted. 5.2mA 5.2mA is the output current's high and low states. 74HC is its series number. 14 terminations have been made so far. It has 2 functions that enhance user experience significantly. I would like to point out that this chip is part of HC/UH. Trying searching with 74HC21 will yield device variants. Into the part body are injected 14 pins. There are many applications for this logic device, mounted at Through Hole. You can find the functions of the 14 pins in the datasheets. Inputs for the part are set to 4. It has 2μA current flowing through it when it is quiescent. A logic device of this type is a Gates. The part bears a load capacitance of 50pF. To supply the device, it requires a voltage of 2V. When 6V is reached, the maximum supply voltage (Vsup) is reached. 5.2mA is the output current of the device. As part of the device, there are 1 outputs. Operation is based on 2 elements in total. It is specified that the operating supply voltage for the chip will be 5V volts.
