*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent
damage to the device. This is a stress rating
only and functional operation of the device at
these or any other conditions beyond those
indicated in the operational sections of this
specification is not implied. Exposure to abso-
lute maximum rating conditions for extended
periods may affect device reliability.
Note: 1. Minimum voltage is -0.6V DC which may undershoot to -2.0V for pulses of less than 20 ns. Maximum output pin voltage is
VCC + 0.75V DC which may overshoot to +7.0V for pulses of less than 20 ns.

3. VH = 12.0 ± 0.5V.
4. Two identifier bytes may be selected. All Ai inputs are held low (VIL), except A9 which is set to VH and A0 which is toggled
low (VIL) to select the Manufacturer’s Identification byte and high (VIH) to select the Device Code byte.
