TLC272CDRG4 datasheet by Texas Instruments

TLC272CDRG4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for TLC272CDRG4?
  The recommended operating voltage range for TLC272CDRG4 is 4.5V to 16V, although it can operate up to 18V with reduced performance.
• How do I handle the input voltage range for the TLC272CDRG4?
  The input voltage range for the TLC272CDRG4 is -0.3V to VCC + 0.3V. Ensure that the input voltage does not exceed the supply voltage (VCC) to prevent damage to the device.
• What is the maximum output current for the TLC272CDRG4?
  The maximum output current for the TLC272CDRG4 is 20mA per channel. Exceeding this limit may cause the device to overheat or malfunction.
• How do I ensure the TLC272CDRG4 operates within its thermal limits?
  Ensure that the device is properly mounted on a heat sink or PCB with good thermal conductivity, and that the ambient temperature does not exceed 70°C (158°F) for commercial grade or 85°C (185°F) for industrial grade.
• What is the purpose of the null pin on the TLC272CDRG4?
  The null pin (pin 8) is used to adjust the output voltage offset. Connecting it to the output pin (pin 6 or 7) can help to reduce the output voltage offset to near zero.
