CD74HC21MT Overview
The part comes in 14-SOIC (0.154, 3.90mm Width) packaging, which makes it convenient to ship overseas. High reliability is provided by advanced packaging method Tape & Reel (TR). AND Gate logic governs its operation. A voltage of 2V~6V is required for the part to function properly. Operating temperature around -55°C~125°C extended. Mounted in Surface Mount. 5.2mA 5.2mA is the output current's high and low states. A 74HC series product. There are 14 terminations totally. A significant improvement in the user experience can be achieved by the part since it has 2 functions. In HC/UH, this chip plays an important role. 74HC21 can be used to search for device variants. Part bodies are injected with 14 pins. This logic device is widely used in a wide variety of applications because it is Surface Mount mounted. The functions of 14 pins can be found in the datasheets. There are 4 inputs on this part. In the quiescent state, the part has 2μA current flowing through it. This logic device is a typical Gates. It has a capacitance of 50pF when loaded. In order for the device to work, a minimum voltage of 2V is required. When 6V is reached, the maximum supply voltage (Vsup) is reached. In this case, the output current is rated as 5.2mA. As part of the device, there are 1 outputs. A logical operation through a gate of 2.
