QT60320D

      The QT60320D is designed as 32-key QMatrix charge-transfer IC with typical applications of security keypanels, industrial keyboards, appliance controls, outdoor keypads, ATM machines, touch-screens, automotive panels and machine tools.
      The QT60320D has many features.The first one is that it would create 32 'touch buttons' through any dielectric.The second one is that it would be 100% autocal for life - no adjustments required.The third one is 'N' key rollover: senses all 32 keys in parallel.The fourth one is keys individually adjustable for sensitivity.The fifth one is mix 'n match key sizes & shapes in one panel.The sixth one is tolerates a 20:1 variance in key sizes on a panel.The seventh one is panel thicknesses to 5 cm or more.The eighth one is back lit keys possible with ITO electrodes.The ninth one is LED status function drives.The tenth one is user-addressable multifunction drive pins.The next one is user-addressable internal eeprom.The next one is simple, universal serial interface.The next one is 5V single supply operation.The next one is that it would have 44-pin TQFP package.The last one is one square inch (6.5 square cm) of PCB required.That are all the features.
      Some absolute maximum specifications of QT60320D have been concluded into several points as follow.The first one is about its operating temperature which would be from -40°C to +105°C.The second one is about its storage temperature which would be from -55°C to +125°C.The third one is about its Vdd which would be from -0.5 to +6.0V.The fourth one is about its max continuous pin current, any control or drive pin which would be ±20mA.The fifth one is about its short circuit duration to ground, any pin which would be infinite.The sixth one is about its short circuit duration to Vdd, any pin which would be infinite.The last one is about its voltage forced onto any pin which would be from -0.6V to (Vdd + 0.6) Volts.
