Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any

of these limits are exceeded, device functionality should not be assumed, damage may occur

and reliability may be affected.

TSSOP Package: − 6.1 mW/°C from 65° to 125°C

This device contains protection

circuitry to guard against damage

due to high static voltages or elec-

tric fields. However, precautions

must be taken to avoid applications

of any voltage higher than maxim-

um rated voltages to this high−im-

pedance circuit. For proper opera-

tion, Vin and Vout should be con-

strained to the range GND v (Vin

or Vout) v VCC.

Unused inputs must always be

tied to an appropriate logic voltage

level (e.g., either GND or VCC). Un-

used outputs must be left open.
