5 / 7 page  LM193, LM193A, LM293, LM293A, LM393, LM393A Electrical Characteristics 5/15 4 Electrical Characteristics Table 3. VCC + = +5V, V CC -= 0V, T amb = +25°C (unless otherwise specified) Symbol Parameter LM193A - LM293A LM393A LM193- LM293 LM393 Unit Min. Typ. Max. Min Typ. Max. Vio Input Offset Voltage - note (1) Tamb = +25°C Tmin ≤ Tamb ≤ Tmax 1. At output switch point, Vo ≈ 1.4V, Rs = 0 with VCC + from 5V to 30V, and over the full common-mode range (0V to V CC + - 1.5V). 12 4 15 9 mV Iio Input Offset Current Tamb = +25°C Tmin ≤ Tamb ≤ Tmax 325 100 550 150 nA Iib Input Bias Current (I+ or I-) - note (2) Tamb = +25°C 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 no loading charge exists on the reference of input lines. 25 100 300 25 250 400 nA Avd Large Signal Voltage Gain VCC = 15V, RL = 15kΩ, Vo = 1V to 11V 50 200 50 200 V/mV ICC Supply Current (all comparators) VCC = +5V, no load VCC = +30V, no load 0.4 1 1 2.5 0.4 1 1 2.5 mA Vicm Input Common Mode Voltage Range - note (3) VCC = 30V Tamb = +25°C Tmin ≤ Tamb ≤ Tmax 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. 0 0 VCC + -1.5 VCC + -2 0 0 VCC + -1.5 VCC + -2 V Vid Differential Input Voltage -note (4) 4. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained. VCC + VCC + VOL Low Level Output Voltage Vid = -1V, Isink = 4mA Tamb = +25°C Tmin ≤ Tamb ≤ Tmax 250 400 700 250 400 700 mV IOH High Level Output Current (Vid = 1V) VCC = Vo = 30V Tamb = +25°C Tmin ≤ Tamb ≤ Tmax 0.1 1 0.1 1 nA µA ISINK Output Sink Current Vid= 1V, Vo = 1.5V 6 16 6 16 mA tre Response Time - note (5) RL= 5.1kΩ connected to VCC + 5. 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 bellow the negative power supply, if used). 1.3 1.3 µs trel Large Signal Response Time RL= 5.1kΩ connected to VCC +, e l = TTL, V(ref) = +1.4v 300 300 ns |
