TLC542IN datasheet by Texas Instruments

TLC542IN Frequently Asked Questions (FAQs)

• What is the maximum current that the TLC542IN can handle?
  The TLC542IN 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 TLC542IN is properly powered?
  The TLC542IN requires a single 5V power supply, and it's recommended to use a decoupling capacitor of at least 0.1uF between VCC and GND to ensure proper operation.
• What is the purpose of the OE (Output Enable) pin?
  The OE pin is used to enable or disable the output of the TLC542IN. When OE is low, the outputs are enabled, and when OE is high, the outputs are disabled and in a high-impedance state.
• How do I program the TLC542IN to output a specific voltage?
  The TLC542IN 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 TLC542IN?
  The settling time of the TLC542IN is typically around 10us, but it can vary depending on the output voltage and the load capacitance.
