SN74HC21DE4 Overview
The part comes in 14-SOIC (0.154, 3.90mm Width) packaging, which makes it convenient to ship overseas. To ensure high reliability, a new packaging method Tube is used. Based on the AND Gate logic principle, it works. To ensure the part's full function, a voltage of 2V~6V is needed. An extended operating temperature of -40°C~85°C degrees Celsius. There is a hole in Surface Mount for mounting the part. Output current is 5.2mA 5.2mA in the high and low states. 74HC is the series it belongs to. There are 14 terminations totally. There are 2 features that significantly enhance the user experience. It represents the HC/UH product family. Use 74HC21 when searching for device variants. 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 Surface Mount mounting. Please refer to the datasheets for 14 pins functions. There are 4 inputs on this part. In the quiescent state, the part has 2μA current flowing through it. A logic device of this type is a Gates. It has a capacitance of 50pF when loaded. It requires a minimal voltage of 2V to supply the device. Upon reaching 6V, the maximum supply voltage (Vsup) is reached. 5.2mA is the output current of the device. There are 1 outputs on the device. During operation, there are 2 elements. In the specification of the chip, it is specified that the operating supply voltage will be 5V volts.
