M-980-02
Absolute Maximum Ratings
DC Supply Voltage (V_DD - V_SS)
6.0V
Voltage on SIGNAL IN(V_DD+ 0.5V) to (V_SS-12V)
Voltage on Any Pin Except SIGNAL IN
(V_DD + 0.5V) to V_SS -0.5V
Storage Temperature Range
-65° to 150°C
Operating Temperature
-40°C to 85°C
Lead Soldering Temperature
260° for 5 seconds
Note:
Exceeding these ratings may permanently damage the M-980-02.
Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at these or
any other conditions beyond those indicated in the opera-
tional sections of this data sheet is not implied. Exposure of
the device to the absolute maximum ratings for an extend-
ed period may degrade the device and effect its reliability.

Descriptions
Signal input AC or DC coupled (see level limitations elsewhere).
Active output indicating signal detection. Activated by ENABLE.
Enables DETECT output. Used to mask signal activity.
Most positive power supply pin.
Internally generated reference voltage. (V_SS + V_DD) /2 volts.
Most negative power supply pin.
Crystal attachment pins. XIN may be used as the input for an external 3.58 MHz clock.
