LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134); all voltages referenced to ground.
HANDLING
All pins are protected against ESD by means of internal clamping diodes. The protection circuit meets the following
specification:
Human body model: C = 100 pF; R = 1.5 k
; all pins >3000 V
Machine model: C = 200 pF; R = 0
; all pins >200 V.
At an ambient temperature of 90
°C, all pins meet the following specification:
Itrigger > 100 mA or Vpin > 1.5VCC(max)
Itrigger < 100 mA or Vpin < 0.5VCC(max)
