The ● denotes specifications which apply over the full operating tempera-
ture range, otherwise specifications are at T

Note 1: Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2: f
C
is the frequency where the gain is –3dB with respect to the input
signal.
Note 3: The external or driven clock frequency is divided by either 1, 2 or 4
depending upon the voltage at Pin 4. For the N8 package, when Pin 4 = V
+
,
ratio = 1; when Pin 4 = GND, ratio = 2; when Pin 4 = V
–
, ratio = 4.
