Description
The AT22LV10 and AT22LV10L are low voltage compatible CMOS high performance
Programmable Logic Devices (PLDs). Speeds down to 20 ns and power dissipation
as low as 14.4 mW are offered. All speed ranges are specified over the 3.0V to 5.5V
range. All pins offer a low
10
A leakage.

The AT22LV10L provides the optimum low power CMOS
PLD solution, with low DC power (1 mA typical at V
CC
=
3.3V) and full CMOS output levels. The AT22LV10L signifi-
cantly reduces total system power, allowing battery pow-
ered operation.
Full CMOS output levels help reduce power in many other
system components.
The AT22LV10 and AT22LV10L logic architectures are
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.
Two additional product terms are included to provide syn-
chronous preset and asynchronous reset. These terms are
common to all ten registers. All registers are automatically
cleared upon power up.
Register preload simplifies testing. A security fuse prevents
unauthorized copying of programmed fuse patterns.
*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 whihc may undershoot
to -2.0V for pulses of less than 20 ns. Maximum pin
voltage is V
CC
+ 0.75V dc which may undershoot to
V
CC
+ 2.0V for pulses of less than 20 ns.
