TLC542CDWR datasheet by Texas Instruments

TLC542CDWR Frequently Asked Questions (FAQs)

• What is the maximum current that the TLC542CDWR can sink or source?
  The TLC542CDWR can sink or source up to 25mA of current per output.
• How do I ensure that the TLC542CDWR outputs are in a high-impedance state during power-up or power-down?
  To ensure that the outputs are in a high-impedance state during power-up or power-down, connect a 1kΩ to 10kΩ pull-up resistor to VCC on each output pin.
• What is the recommended operating voltage range for the TLC542CDWR?
  The recommended operating voltage range for the TLC542CDWR is 4.5V to 5.5V.
• How do I reduce electromagnetic interference (EMI) when using the TLC542CDWR?
  To reduce EMI, use a ground plane, keep signal traces short, and use a low-pass filter or a ferrite bead on the output lines.
• Can I use the TLC542CDWR as a level translator?
  Yes, the TLC542CDWR can be used as a level translator. It can translate logic levels from 3.3V to 5V or vice versa.
