TLC7524ED datasheet by Texas Instruments

TLC7524ED Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of TLC7524ED?
  The TLC7524ED can operate up to 100 kHz, but the maximum frequency depends on the specific application and the load capacitance.
• How do I ensure the TLC7524ED is properly powered?
  The TLC7524ED requires a single 5V power supply, and it's essential to decouple the power pins with a 0.1uF ceramic capacitor to ensure stable operation.
• What is the maximum output current of TLC7524ED?
  The TLC7524ED can source or sink up to 100mA of current per channel, but it's recommended to limit the current to 50mA per channel for reliable operation.
• How do I program the TLC7524ED?
  The TLC7524ED is a parallel-input, serial-output shift register, and it can be programmed using a microcontroller or a dedicated IC programmer. The programming sequence is described in the datasheet.
• What is the purpose of the CLR (Clear) pin?
  The CLR pin is an active-low input that resets the shift register and clears the output latches when pulled low. It's used to initialize the device or reset the outputs.
