SN74HC21DG4 Overview
As the part is packed in 14-SOIC (0.154, 3.90mm Width), international shipping is convenient. A high level of reliability can be achieved through the use of an advanced packaging method Tube. AND Gate logic is the basis of its operation. Voltage 2V~6V ensures the part's full functionality. Operation at a temperature around -40°C~85°C. There is a hole in Surface Mount for mounting the part. 5.2mA 5.2mA is the output current's high and low states. The 74HC series contains it. In total, there have been 14 terminations. There are 2 functions that significantly improve the user experience. I would like to point out that this chip is part of HC/UH. Try searching with 74HC21 to find device variants. Into the part body are injected 14 pins. Logic devices with Surface Mount mounting are widely used in many applications. For functions related to 14 pins, please refer to the datasheets. A 4 input is supported by the part. Quiescent parts have 2μA current flowing through them. Gates is a typical logic device. It has a capacitance of 50pF when loaded. A minimum voltage of 2V is required to supply the device. It reaches 6V when the supply voltage is maximal (Vsup). A device with an output current of 5.2mA is rated. 1 outputs are included in the device. The operation uses 2 elements in total. Typical operating voltages for the chip are specified as being z volts when it is first manufactured.
