SN74HC21D Overview
Shipped in 14-SOIC (0.154, 3.90mm Width), the part is easy to ship overseas. High reliability is achieved by using advanced packaging method Tube. Using AND Gate logic, it functions. Voltage 2V~6V ensures the part's full functionality. The operating temperature is extended to around -40°C~85°C. There is Surface Mount mounting in Surface Mount. In the low and high states of output current, the current is 5.2mA 5.2mA. The series 74HC contains it. In total, there are 14 terminations. In addition to 2 functions that significantly boost the user experience, the part includes 2 other features. I would like to point out that this chip is part of HC/UH. Use 74HC21 when searching for device variants. The part body is injected with 14 pins. Many applications include this logic device with a Surface Mount mounting. You can find the functions of the 14 pins in the datasheets. Inputs are limited to 4. Parts in quiescent state carry 2μA current. The logic device in this example is a typical Gates. A load capacitance of 50pF is provided by the part. To supply the device, it requires a voltage of 2V. When 6V is reached, the maximum supply voltage (Vsup) is reached. Device output current is 5.2mA. The device has 1 outputs. In the specification of the chip, it is specified that the operating supply voltage will be 5V volts. This part generates high-quality logic output through its 2 channels.
