6 / 11 page www.fairchildsemi.com 6 AC Electrical Characteristics (Note 4) TA = 25°C, CL = 50 pF, and tr = tf = 20 ns unless otherwise specified Note 4: AC parameters are guaranteed by DC correlated testing. Note 5: The maximum usable resistance RX is a function of the leakage of the Capacitor CX, leakage of the CD4538BC, and leakage due to board layout, surface resistance, etc. Symbol Parameter Conditions Min Typ Max Units tTLH, tTHL Output Transition Time VDD = 5V 100 200 ns VDD = 10V 50 100 ns VDD = 15V 40 80 ns tPLH, tPHL Propagation Delay Time Trigger Operation— A or B to Q or Q VDD = 5V 300 600 ns VDD = 10V 150 300 ns VDD = 15V 100 220 ns Reset Operation— CD to Q or Q VDD = 5V 250 500 ns VDD = 10V 125 250 ns VDD = 15V 95 190 ns tWL, tWH Minimum Input Pulse Width VDD = 5V 35 70 ns A, B, or CD VDD = 10V 30 60 ns VDD = 15V 25 50 ns tRR Minimum Retrigger Time VDD = 5V 0 ns VDD = 10V 0 0 ns VDD = 15V 0 ns CIN Input Capacitance Pin 2 or 14 10 pF Other Inputs 5 7.5 pF PWOUT Output Pulse Width (Q or Q) RX = 100 kΩ VDD = 5V 208 226 244 µs (Note: For Typical Distribution, CX = 0.002 µFVDD = 10V 211 230 248 µs see Figure 6) VDD = 15V 216 235 254 µs RX = 100 kΩ VDD = 5V 8.83 9.60 10.37 ms CX = 0.1 µFVDD = 10V 9.02 9.80 10.59 ms VDD = 15V 9.20 10.00 10.80 ms RX = 100 kΩ VDD = 5V 0.87 0.95 1.03 s CX = 10.0 µFVDD = 10V 0.89 0.97 1.05 s VDD = 15V 0.91 0.99 1.07 s Pulse Width Match between RX = 100 kΩ VDD = 5V ±1% Circuits in the Same Package CX = 0.1 µFVDD = 10V ±1% CX = 0.1 µF, RX = 100 kΩ VDD = 15V ±1% Operating Conditions RX External Timing Resistance 5.0 (Note 5) k Ω CX External Timing Capacitance 0 No Limit pF |
