TLC542CN datasheet by Texas Instruments

TLC542CN Frequently Asked Questions (FAQs)

• What is the maximum current that the TLC542CN can handle?
  The TLC542CN can handle a maximum current of 100mA per channel, with a total current limit of 500mA for all channels combined.
• How do I ensure that the TLC542CN is properly powered?
  The TLC542CN requires a single 5V power supply, and it's recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to ensure proper operation.
• What is the purpose of the EN (enable) pin?
  The EN pin is used to enable or disable the TLC542CN. When EN is high, the device is enabled, and when EN is low, the device is disabled and all outputs are turned off.
• How do I program the TLC542CN to output a specific voltage?
  The TLC542CN is a digital-to-analog converter, and the output voltage is determined by the digital input code. The output voltage is calculated as Vout = (Vref x D) / 256, where Vref is the reference voltage and D is the digital input code.
• What is the settling time of the TLC542CN?
  The settling time of the TLC542CN is typically around 10us, but it can vary depending on the output voltage and the load capacitance.
