Note 1: All devices are 100% tested at T
A
= +25°C. Specifications over -40°C to +125°C are guaranteed by design.
Note 2: Limits are guaranteed by design, not production tested.
Note 3: The logic-input thresholds are tested at V
DD
= 4V and V
DD
= 15V.
Note 4: TTL compatible with reduced noise immunity.
