TLC25M2CD datasheet by Texas Instruments

TLC25M2CD Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of TLC25M2CD?
  The TLC25M2CD can operate up to 2.7 MHz, but it's recommended to operate it at 1.5 MHz or lower for optimal performance and to minimize power consumption.
• How do I ensure the TLC25M2CD is in a stable state during power-up?
  To ensure a stable state during power-up, it's recommended to add a power-on reset (POR) circuit to the VCC pin, and to use a capacitor (e.g., 0.1 μF) between the VCC pin and GND to filter out noise.
• What is the recommended layout and routing for the TLC25M2CD?
  For optimal performance, it's recommended to follow a star-grounding layout, keep analog and digital signals separate, and use short traces and minimal vias. Also, place decoupling capacitors (e.g., 0.1 μF) close to the VCC pin.
• How do I handle the TLC25M2CD's output voltage swing?
  The TLC25M2CD's output voltage swing is dependent on the supply voltage (VCC). To ensure a full output swing, VCC should be at least 2.5 V. If VCC is lower, the output swing will be reduced accordingly.
• What is the TLC25M2CD's input impedance, and how does it affect my circuit design?
  The TLC25M2CD's input impedance is typically around 10 kΩ. This can affect the circuit design, especially when driving the input with a high-impedance source. In such cases, a buffer amplifier or a voltage follower may be necessary to ensure a stable input signal.
