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
V
CC
+ 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 Programming Characteristics.
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
.
