† Notice: Stresses above those listed under “Absolute Maxi-

mum Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the

device at those or any other conditions above those indicated

in the operational listings of this specification is not implied.

Exposure to maximum rating conditions for extended periods

may affect device reliability.

†† See Section 4.1.2 “Input Voltage and Current

Limits”

DC CHARACTERISTICS

Note 1:

The input offset voltage is the center of the input-referred trip points. The input hysteresis is the difference between the

input-referred trip points.

2:

VHYST at differential temperatures is estimated using: VHYST (TA) = VHYST + (TA -25°C) TC1 + (TA - 25°C)2TC2.

3:

Input bias current at temperature is not tested for the SC-70-5 package

4:

Do not short the output above VSS + 10V. Limit the output current to Absolute Maximum Rating of 30 mA. The minimum

VPU test limit was VDD before Dec. 2004 (week code 52).
