† Notice: Stresses above those listed under “Absolute

Maximum 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 rat-

ing conditions for extended periods may affect device

reliability.

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.

VHYST at differential temperatures is estimated using:

VHYST (TA) = VHYST + (TA -25°C) TC1 + (TA - 25°C)

2TC

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

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).
