This current is essentially constant, independent of the state of the output so no loading change exists on the reference or input lines. (2) The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage range is V+ −1.5 V at 25°C, but either or both inputs can go to 30 VDC without damage, independent of the magnitude of V+. (3) The response time specified is a 100-mV input step with 5-mV overdrive. For larger overdrive signals 300 ns can be obtained, see typical performance characteristics section. (4) Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than −0.3 VDC (or 0.3 VDCbelow the magnitude of the negative power supply, if used) (at 25°C). 6.5 Electrical Characteristics (V+ = 5 VDC, TA = 25°C, unless otherwise stated) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT Input offset voltage At output switch point, VO ≃ 1.4 VDC, RS = 0 Ω with V+ from 5 VDC to 30 VDC; and over the full input common- mode range (0 VDC to V+ −1.5 VDC), at 25°C. 2 5 mVDC At output switch point, VO ≃ 1.4 VDC, RS = 0 Ω with V+ from 5 VDC to 30 VDC; and over the full input common- mode range (0 VDC to V+ −1.5 VDC), at 25°C, 0°C ≤ TA ≤ 70°C 9 Input bias current(1) IIN(+) or IIN(−) with output in linear range, VCM = 0 V 25 250 nADC IIN(+) or IIN(−) with output in linear range, VCM = 0 V, 0°C ≤ TA ≤ 70°C 400 Input offset current IIN(+)− IIN(−), VCM = 0 V 5 50 nADC IIN(+)− IIN(−), VCM = 0 V, 0°C ≤ TA ≤ 70°C 150 Input common-mode voltage range(2) V+ = 30 VDC 0 V+ − 1.5 VDC V+ = 30 VDC, 0°C ≤ TA ≤ 70°C V+ – 2 Supply current RL = ∞ on all comparators 0.8 2 mADC RL = ∞, V+ = 36 V 1 2.5 mADC Voltage gain RL ≥ 15 kΩ, V+ = 15 VDC, VO = 1 VDC to 11 VDC 50 200 V/mV Large signal response time VIN = TTL logic swing, VREF = 1.4 VDC, VRL = 5 VDC, RL = 5.1 kΩ 300 ns Response time(3) VRL = 5 VDC, RL = 5.1 kΩ 1.3 μs Output sink current VIN(−)= 1 VDC, VIN(+) = 0, VO ≤ 1.5 VDC 6 16 mADC Saturation voltage VIN(−) = 1 VDC, VIN(+) = 0, ISINK ≤ 4 mA 250 400 mVDC VIN(−) = 1 VDC, VIN(+) = 0, ISINK ≤ 4 mA, 0°C ≤ TA ≤ 70°C 700 Output leakage current VIN(+) = 1 VDC,VIN(−) = 0, VO = 5 VDC 0.1 nADC VIN(+) = 1 VDC, VIN(−) = 0, VO = 30 VDC, 0°C ≤ TA ≤ 70°C 1 µADC Differential input voltage(4) Keep all VINs ≥ 0 VDC (or V–, if used), 0°C ≤ TA ≤ 70°C 36 VDC |
