*NOTICE:
Stresses beyond those listed under “Absolute Maxi-
mum 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 condi-
tions beyond those indicated in the operational sec-
tions of this specification is not implied. Exposure to
absolute maximum rating conditions for extended
periods may affect device reliability.
Note:

Minimum voltage is -0.6V dc which undershoot to -
2.0V for pulses of less than 20 ns. Maximum output
pin voltage is V

= 12.0 ± 0.5V.
Two identifier words may be selected. All inputs are held low (V
IL
), except A9, which is set to V
H
, and A0, which is toggled
low (V
IL
) to select the Manufacturer’s Identification word and high (V
IH
) to select the Device Code word.
