TLC5924RHBR datasheet by Texas Instruments

TLC5924RHBR Frequently Asked Questions (FAQs)

• What is the maximum current that can be sourced or sunk by each output?
  The TLC5924RHBR can source up to 25mA and sink up to 50mA per output, making it suitable for driving LEDs, relays, and other loads.
• How do I ensure that the device is properly powered and initialized?
  The TLC5924RHBR requires a single 3.3V or 5V power supply, and the VCC pin should be decoupled with a 0.1uF capacitor. The device is initialized by bringing the RESET pin high and then low to ensure proper operation.
• What is the maximum frequency of the clock input (CLKIN) and how does it affect the device's operation?
  The maximum frequency of the clock input (CLKIN) is 25MHz. The clock frequency determines the rate at which the device updates the output states, with higher frequencies allowing for faster output switching.
• How do I program the device to output a specific pattern or sequence?
  The TLC5924RHBR can be programmed using a serial interface (SI) to output a specific pattern or sequence. The device can be configured to output a fixed pattern, or it can be dynamically updated using the serial interface.
• What is the purpose of the OE (Output Enable) pin and how does it affect the device's operation?
  The OE pin is used to enable or disable the output drivers. When OE is low, the output drivers are enabled, and when OE is high, the output drivers are disabled, allowing the outputs to be high-impedance.
