Supply voltage 4.5 16 V VCC = 5 V, RL = ¥ 3 6 Supply current (each timer section) mA VCC = 15 V, RL = ¥ (low state)(1) 10 14 Initial accuracy 0.75% Drift with temperature 50 ppm/°C Timing error, RA = 1 k to 100 kΩ, monostable C = 0.1 μF(2) Accuracy over temperature 1.5% Drift with supply 0.1 %/V Initial accuracy 2.25% Drift with temperature 150 Timing error, RA, RB = 1 k to 100 kΩ, ppm/°C astable C = 0.1 μF(2) Accuracy over temperature 3% Drift with supply 0.30 %/V VCC = 15 V 4.5 5 5.5 Trigger voltage V VCC = 5 V 1.25 1.67 2 Trigger current 0.2 1 µA Reset voltage 0.4 0.5 1 V Reset current 0.1 0.6 mA VTH = V-control(3) 0.03 0.1 µA Threshold current VTH = 11.2 V 250 nA VCC = 15 V 9 10 11 Control voltage level and threshold voltage V VCC = 5 V 2.6 3.33 4 Pin 1, 13 leakage output high 1 100 nA VCC = 15 V, I = 15 mA 180 300 Pin 1, 13 sat output low(4) mV VCC = 4.5 V, I = 4.5 mA 80 200 ISINK = 10 mA 0.1 0.25 ISINK = 50 mA 0.4 0.75 VCC = 15 V Output voltage drop (low) ISINK = 100 mA 2 2.75 V ISINK = 200 mA 2.5 VCC = 5 V, ISINK = 5 mA 0.25 0.35 ISOURCE = 200 mA, VCC = 15 V 12.5 Output voltage drop (high) ISOURCE = 100 mA, VCC = 15 V 12.75 13.3 V VCC = 5 V 2.75 3.3 Rise time of output 100 ns Fall time of output 100 ns Initial timing accuracy 0.1% 2% ppm/°C Matching Timing drift with temperature See (5) ±10 characteristics Drift with supply voltage 0.2 0.5 %/V (1) Supply current when output high typically 1 mA less at VCC = 5 V. (2) Tested at VCC = 5 V and VCC = 15 V. (3) This will determine the maximum value of RA + RB for 15-V operation. The maximum total (RA + RB) is 20 MΩ. (4) No protection against excessive pin 1, 13 current is necessary providing the package dissipation rating will not be exceeded. (5) Matching characteristics refer to the difference between performance characteristics of each timer section.
