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.
Notes: 1. X can be V
IL
or V
IH.
2. Refer to the programming characteristics tables in this data sheet.
3. V
H
= 12.0
±
0.5V.
4. Two identifier words may be selected. All Ai 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.
5. Standby V
CC
current (I
SB
) is specified with V
PP
= V
CC
. V
CC
> V
PP
will cause a slight increase in I
SB
.

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 absolute maximum rating
