These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) "Absolute Maximum Ratings" are those parameter values beyond which the life and operation of the device cannot be ensured. The
stating herein of these maximums shall not be construed to imply that the device can or should be operated at or beyond these values.
The table of "Electrical Characteristics" specifies acceptable device operating conditions.

(1) Current flow into device pins is defined as positive. Current flow out of device pins is defined as negative. All voltages are stated
referenced to V
EE
= 0 Volts.
(2) Typical values are stated for V
CC
= +3.3V and T
A
= +25°C.
(3) Specification is ensured by characterization.
(4) The maximum input voltage swing assumes a nonstressing, DC-balance signal; specifically, the SMPTE-recommended color bar test
signal. Pathological or other stressing signals may not be used. This specification is for 0m cable only.
(5) Supply current depends on the amount of cable being equalized. The current is highest for short cable and decreases as the cable
length is increased. Refer to Figure 2.
