identical to the familiar 22V10. Each output is allocated
from eight to 16 product terms, which allows highly com-
plex logic functions to be realized.

*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:
1. Minimum voltage is -0.6V dc whihc may undershoot
to -2.0V for pulses of less than 20 ns. Maximum pin
voltage is VCC + 0.75V dc which may undershoot to
VCC + 2.0V for pulses of less than 20 ns.

Preload of Registered Outputs
The registers in the AT22LV10 and AT22LV10L are pro-
vided with circuitry to allow loading of each register asyn-
chronously with either a high or a low. This feature will
simplify testing since any state can be forced into the regis-
ters to control test sequencing. A VIH level on the I/O pin
will force the register high; a VIL will force it low, indepen-
dent of the polarity bit (C0) setting. The preload state is
entered by placing an 11.5V to 13V signal on pin 8 on
DIPs, and pin 10 on SMPs. When the clock pin is pulsed
high, the data on the I/O pins is placed into the ten regis-
ters.

Power-Up Reset
The registers in the AT22LV10 and AT22LV10L are
designed to reset during power up. At a point delayed
slightly from VCC crossing 2.5V, all registers will be reset
to the low state. The output state will depend on the polarity
of the output buffer.
This feature is critical for state machine initialization. How-
ever, due to the asynchronous nature of reset and the
uncertainty of how VCC actually rises in the system, the fol-
lowing conditions are required:
1. The VCC rise must be monotonis;
2. After reset occurs, all input and feedback setup
times must be met before driving the clock pin high,

Erasure Characteristics
The entire fuse array of an AT22LV10 or AT22LV10L is
erased after exposure to ultraviolet light at a wavelength of
2537 Å. Complete erasure is assured after a minimum of
20 minutes exposure using 12,000 µW/cm2 intensity lamps
spaced one inch away from the chip. Minimum erase time
for lamps at other intensity ratings can be calculated from
the minimum integrated erasure dose of 15 W•sec/cm2. To
prevent unintentional erasure, an opaque label is recom-
mended to cover the clear window on any UV erasable
PLD which will be subjected to continuous fluorescent
indoor lighting or sunlight.
