ELECTRICAL CHARACTERISTICS (Complete Filter) The ● denotes the specifications which apply over the full
operating temperature range, otherwise specifications are at VS = ±5V, TA = 25°C, TTL clock input level, unless otherwise specified.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
