TLC254CD datasheet by Texas Instruments

TLC254CD Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with TLC254CD?
  The maximum clock frequency for TLC254CD is 3 MHz. However, it's recommended to use a clock frequency of 1 MHz or less to ensure reliable operation.
• How do I handle the power-on reset (POR) of TLC254CD?
  The TLC254CD has a built-in POR circuit that resets the device when the power supply voltage (VCC) rises above 1.5 V. To handle POR, ensure that the VCC pin is properly decoupled with a capacitor and that the clock signal is not applied until VCC is stable.
• What is the recommended operating voltage range for TLC254CD?
  The recommended operating voltage range for TLC254CD is 4.5 V to 5.5 V. Operating the device outside this range may affect its performance and reliability.
• How do I interface TLC254CD with a microcontroller?
  The TLC254CD can be interfaced with a microcontroller using a serial interface (SI) protocol. The microcontroller can send data to the TLC254CD using the SI protocol, and the TLC254CD will convert the data into analog output voltages.
• What is the settling time of TLC254CD?
  The settling time of TLC254CD is typically around 10 μs. This is the time it takes for the output voltage to settle within 1/2 LSB of its final value after a code change.
