Note: 1. Exposure to conditions beyond those listed under Absolute Maximum Ratings may adversely affect the life and reliability of
the device.
2. Minimum voltage is -0.6V DC which may undershoot to -2.0V for pulses of less than 20ns. Maximum output pin voltage is
V
DD
+0.75V DC which may overshoot to +7.0V for pulses of less than 20ns.
