7.
τ = kRxCx and k = 0.7 for the output pulse width corresponding to Rx = 10 kW, Cx = 0.1 mF.
8.
τ = kRxCx and k = 0.79 for the output pulse width corresponding to Rx = 100 kW, Cx = 1 nF.
9. Pulse width match variation between ICs (parttopart) is defined with identical Rx, Cx, VCC and a specific temperature.
