Notes
  • When counting up, TC goes low when the count is 15.
  • When counting down, TC goes low when the count is 0.
  • TC is always high when CE is high (counting is disabled).

Note
Data is maintained by an independent source and accuracy is not guaranteed. Check with the manufacturer's datasheet for up-to-date information.
