AT42QT1111-AU Product Details

AT42QT1111-AU Overview


It is packaged using materials from Tape & Reel (TR). Mounting it on a PCB requires Surface Mount. A significant reason for 32-TQFP's popularity in the electronic industry is its low package cost. The 1.8V~5.5V Supply Voltage ensures its normal operation. We use Up to 11 inputs. It belongs to the Type Buttons for standard grade applications. Keeping its operational temperature at -40°C~85°C is always a good idea. Due to its high cost-down performance ratio, the QTouch™ Series provides the best value on the market. The current supply for this system is provided by 12mA. Drivers for LEDs have Up to 7 channels. The current supply of the device has been set to 12mA. As long as the pin number remains 32, the component is in good shape. AT42QT1111 represents the most important part of the gadget. The package of the supplier device is 32-TQFP (7x7). There is a Surface Mount mount that includes it. There are 11 channels over which data is transmitted. The temperature should be warmer when it is operating than when it is not. In this case, 85°C is the maximum Operating Temperature.
