In 3.3V mode, feed 3.3V to VIN
In 2.5V mode, leave floating
Power supply pins CML/analog
2.5V mode, connect to 2.5V supply
3.3V mode, connect 0.1uF cap to each VDD pin
Ground pad (DAP - die attach pad)
Notes:
LVCMOS inputs without the “FLOAT” conditions must be driven to a logic low or high at all times or operation is not guaranteed.
Input edge rate for LVCMOS/FLOAT inputs must be faster than 50 ns from 10–90%.
For 3.3V mode operation, VIN pin = 3.3V and the "VDD" for the 4-level input is 3.3V.
For 2.5V mode operation, VDD pin = 2.5V and the "VDD" for the 4-level input is 2.5V.
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” indicate limits beyond which damage to the device may occur, including inoperability and degradation of
device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or
other conditions beyond those indicated in the Recommended Operating Conditions is not implied. The Recommended Operating
Conditions indicate conditions at which the device is functional and the device should not be operated beyond such conditions. Absolute
Maximum Numbers are guaranteed for a junction temperature range of -40°C to +125°C. Models are validated to Maximum Operating
Voltages only.
