Note: 1. These are the allowable values up to Ta = 55 °C. Derate by 8.3mW/°C above that temperature.
2. These are the allowable values up to Ta = 45 °C mounting on 30% wiring density glass epoxy board. Derate
by 7.14mW/°C above that temperature.
3. Short circuit between the output and VCC will be a cause to destory the circuit. The maximum output current
is about 20mA for any supply voltage.

Notes: 1. VREF = 1.4V and RS = 50Ω, when VO = 1.4V at output switching point.
2. Under linear operation.
VIN (–) = 0, VIN (+) ≥ 1V, VO = 5V
3. Common mode input voltage or each one of the input signal should not be less than –0.3V.
4. This is a value to 100mV input step voltage with 5mV over drive.
