All limits apply for TA = TJ = TMIN to TMAX unless otherwise specified. PARAMETER TEST CONDITIONS MIN(1) TYP(2) MAX(1) UNIT DIGITAL OUTPUT AND INPUT IOUT(1) Logical 1 Output Leakage Current (3) TA = 25°C V+ = +5.0 V 0.001 1 µA IOUT = +1.2 mA and V + ≥ 2.7 V; VOUT(0) Logical 0 Output Voltage 0.4 V IOUT = +3.2 mA and V + ≥ 4.5 V(4) ISOURCE = 500 µA, V + ≥ 2.7 V 0.8 × V+ V VOUT(1) Logical 1 Push-Pull Output Voltage ISOURCE = 800 µA, V +≥ 4.5 V V+ − 1.5 V VIH HYST Input Logical 1 Threshold Voltage 0.8 × V+ V VIL HYST Input Logical 0 Threshold Voltage 0.2 × V+ V (3) The 1-µA limit is based on a testing limitation and does not reflect the actual performance of the part. Expect to see a doubling of the current for every 15°C increase in temperature. For example, the 1-nA typical current at 25°C would increase to 16 nA at 85°C. (4) Take care to include the effects of self heating when setting the maximum output load current. The power dissipation of the LM26 would increase by 1.28 mW when IOUT = 3.2 mA and VOUT = 0.4 V. With a thermal resistance of 250°C/W, this power dissipation would cause an increase in the die temperature of about 0.32°C due to self heating. Self heating is not included in the trip point accuracy specification. 7.6 Typical Characteristics Figure 1.
