TLC7705IP Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for TLC7705IP?
  The recommended operating voltage range for TLC7705IP is 4.5V to 18V.
• How do I ensure the TLC7705IP is properly powered up and initialized?
  To ensure proper power-up and initialization, connect the VCC pin to a stable voltage source, and ensure the EN (enable) pin is high. Also, ensure the capacitor values for the oscillator circuit are within the recommended range.
• What is the purpose of the EN (enable) pin, and how do I use it?
  The EN pin is an active-high enable input that allows the device to be enabled or disabled. When EN is high, the device is enabled, and when EN is low, the device is disabled and consumes minimal power.
• How do I choose the correct oscillator frequency for my application?
  The oscillator frequency depends on the specific application requirements. The TLC7705IP can operate at frequencies up to 1.2 MHz. Choose a frequency that meets your application's timing requirements, and ensure the oscillator circuit is properly configured.
• What is the maximum output current capability of the TLC7705IP?
  The TLC7705IP can sink up to 50 mA of current per output pin, making it suitable for driving small loads such as LEDs or small relays.
