Full range for LM211Q is −40 °C to 125°C. ‡ All typical values are at TA = 25°C. NOTES: 7. The offset voltages and offset currents given are the maximum values required to drive the collector output up to 14 V or down to 1 V with a pullup resistor of 7.5 k Ω to VCC+. These parameters actually define an error band and take into account the worst-case effects of voltage gain and input impedance. 8. The strobe should not be shorted to ground; it should be current driven at −3 mA to −5 mA (see Figures 13 and 27). switching characteristics, VCC± = ±15 V, TA = 25°C PARAMETER TEST CONDITIONS TYP UNIT Response time, low-to-high-level output RC = 500 Ω to 5 V, CL = 5 pF, See Note 9 115 ns Response time, high-to-low-level output RC = 500 Ω to 5 V, CL = 5 pF, See Note 9 165 ns NOTE 9: The response time specified is for a 100-mV input step with 5-mV overdrive and is the interval between the input step function and the instant when the output crosses 1.4 V. |
