TLC548CDR datasheet by Texas Instruments

TLC548CDR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for TLC548CDR?
  The recommended operating voltage range for TLC548CDR is 4.5V to 16V. However, it can operate up to 18V, but with reduced performance and reliability.
• How do I ensure the TLC548CDR is properly powered up and initialized?
  To ensure proper power-up and initialization, it is recommended to follow a slow power-up ramp (typically 10ms to 100ms) and to hold the CLR (clear) pin low for at least 100ns after power-up to reset the device.
• What is the maximum clock frequency that the TLC548CDR can handle?
  The TLC548CDR can handle clock frequencies up to 1.5MHz. However, the maximum clock frequency may vary depending on the specific application and operating conditions.
• How do I interface the TLC548CDR with a microcontroller?
  The TLC548CDR can be interfaced with a microcontroller using a serial interface, such as SPI or I2C. The specific interface protocol will depend on the microcontroller and the application requirements.
• What is the purpose of the CLR (clear) pin on the TLC548CDR?
  The CLR pin is used to reset the TLC548CDR to its initial state. When the CLR pin is pulled low, the device is reset, and all counters and registers are cleared.
