Note 1:

tR and tPLH depend on the load (RL and CL); these specifications are valid for the indicated load only.

Propagation Delay Skew is defined as: tPDS = tPLH - tPHL.

DC CHARACTERISTICS (CONTINUED)

Electrical Specifications: Unless otherwise indicated, VDD = +1.6V to +5.5V, VSS = GND, TA = 25°C, VIN+ = VDD/2,

VIN– = VSS, RPU =2.74 kΩ to VPU = VDD (Refer to Figure 1-3).

Conditions

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).
