Unit Vio Input Offset Voltage (1) 1. At output switch point, VO ≈ 1.4V, RS = 0Ω with VCC + from 5V to 30V and over the full input common-mode range (0V to VCC -1.5V). Tmin. ≤ Tamb ≤ Tmax. 15 9 mV Iio Input Offset Current Tmin. ≤ Tamb ≤ Tmax. 550 150 nA Iib Input Bias Current (2) 2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference or input lines. Tmin. ≤ Tamb ≤ Tmax. 25 250 400 nA Avd Large Signal Voltage Gain VCC = 15V, RL = 15kΩ, Vo = 1 to 11V 50 200 V/mV ICC Supply Current VCC = 5V, no load VCC = 30V, no load 0.2 0.5 0.5 1.25 mA Vicm Input Common Mode Voltage Range (3) 3. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC + –1.5V, but either or both inputs can go to +30V without damage. Tmin. ≤ Tamb ≤ Tmax. 0 0 VCC + -1.5 VCC + -2 V Vid Differential Input Voltage (4) 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 – 0.3V (or 0.3V below the negative power supply, if used). VCC + V Isink Output Sink Current Vid = -1V, VO = 1.5V 6 16 mA VOL Low Level Output Voltage Vid = 1V, VCC = VO = 30V Tmin. ≤ Tamb ≤ Tmax. 250 400 700 mV IOH High Level Output Current Vid = 1V, VCC = VO = 30V Tmin. ≤ Tamb ≤ Tmax. 0.1 1 nA µA tre Small Signal Response Time RL = 5.1kΩ to VCC + (5) 5. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained. 1.3 µs trel Large Signal Response Time Vi = TTL, Vref = +1.4V, RL = 5.1kΩ to VCC + 300 ns |
