SN74HC21DR Overview
Due to its 14-SOIC (0.154, 3.90mm Width) packaging, the part is convenient for international shipping. This high-reliability packaging method uses advanced packaging methods Cut Tape (CT). Based on the AND Gate logic principle, it works. Ensure the part's full functionality by setting the voltage to 2V~6V. Operational temperature extended around -40°C~85°C. Surface Mount is the location of the part. High and low output current states are both 5.2mA 5.2mA. 74HC is the series it belongs to. 14 terminations have been made so far. It has 2 functions that enhance user experience significantly. It represents the HC/UH product family. If you are looking for device variants, try search with 74HC21. A total of 14 pins are injected into the part body. Many applications require the use of this logic device with its Surface Mount mounting. You can find the functions of the 14 pins in the datasheets. It supports inputs of 4. The part has 2μA current flowing through it in the quiescent state. A logic device of this type is a Gates. A 50pF load capacitance is present in the part. Devices require a minimum voltage of 2V. As soon as Vsup reaches 6V, the maximal supply voltage is achieved. There is an industry TR method included. The device's output current is rated 25mA. A device with 1 outputs is available. For operation, there are 2 elements. In the specification of the chip, it is specified that the operating supply voltage will be 5V volts.
