range

(1)

All limits are ensured at room temperature (standard typeface) and at temperature extremes. All room temperature limits are 100%

production tested. All limits at temperature extremes are specified via correlation using standard Statistical Quality Control (SQC)

methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).

(2)

Typical numbers are at 25°C and represent the most likely norm.

VOUT = 2.5 V
