Timimg of 4060 counter-oscillator

Question

I'm using a CD4060B counter/oscillator and need to know the internal timing of the RESET operation. TI's 4060B datasheet says that the minimum input reset pulse width is 30 ns at 10 V, and the reset propagation delay is 80 ns.

When calculating the time for a RESET does the propagation time start after the minimum Reset pulse width? Then is the output transition time of 50 ns added for a complete reset operation?

Answer 1

The \$t_{PHL}\$Reset = off prop delay is more than double the \$t_W\$ Reset=on (H) minimum pulse width .

The \$t_{PHL}\$Off delay begins after the leading edge of Reset= ON \$t_W\$ width so it these delays are not cumulative.
