Electrical characteristics at VCC + = 5 V, V CC - = GND, T amb = 25° C (unless otherwise specified) Symbol Parameter Min. Typ. Max. Unit Vio Input offset voltage (1) Tmin ≤ Tamb ≤ Tmax 1. At output switch point, VO ≈ 1.4 V, RS = 0 with VCC + from 5 V to 30 V, and over the full input common- mode range (0 V to VCC + –1.5 V). 17 15 mV Iio Input offset current Tmin ≤ Tamb ≤ Tmax 550 150 nA Iib Input bias current (II + or I I -) (2) Tmin ≤ Tamb ≤ Tmax 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 there is no loading charge on the reference of input lines. 25 250 400 nA Avd Large signal voltage gain (VCC = 15 V, RL =15kΩ, Vo = 1 to 11 V) 25 200 V/mV ICC Supply current (all comparators) VCC = +5 V, no load VCC = +30 V, no load 1.1 1.3 2 2.5 mA Vid Differential input voltage(3) 3. The response time specified is for a 100 mV input step with 5 mV overdrive. VCC + V VOL Low level output voltage Vid = -1V, Isink = 4 mA Tmin ≤ Tamb ≤ Tmax 250 400 700 mV IOH High level output current (VCC =Vo = 30 V, Vid = 1 V) Tmin ≤ Tamb ≤ Tmax 0.1 1 nA µA Isink Output sink current (Vid = -1 V,Vo = 1.5 V) 6 16 mA tres Small signal response time(4) (RL = 5.1 kΩ connected to VCC +) 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 V (or 0.3 V below the negative power supply, if used). 1.3 µs trel Large signal response time(5) TTL input (Vref = +1.4 V, RL =5.1 kΩ to VCC +) Output signal at 50% of final value Output signal at 95% of final value 5. Maximum values are guaranteed by design. 500 1 ns µs |
