4.3 Characteristics
Note:
The electrical characteristics involve the spread of values guaranteed within the specified supply voltage
and ambient temperature range T
A from
– 25
°C to 85 °C Typical values represent the median values,
which are related to production processes. If not otherwise stated, a supply voltage of V
VCC = 15 V is
assumed..
