Description
The AT22LV10 and AT22LV10L are low volta ge compat ible CMO S high perfor mance
Programmable Logic Devices (PLDs). Speeds down to 20 ns and po wer dissipation
as low as 14.4 mW ar e offered . All sp eed rang es are spe cifi ed over th e 3.0V to 5. 5V
range. All pins offer a low ±10 µA leakage.

The AT22LV10L provides the optimum low power CMOS
PLD solution, with lo w DC power (1 mA typical at V
CC
=
3.3V) and full CMOS output le ve ls. The AT2 2LV 10L sig ni ficantly reduces total system power, allowing battery powered operation.
Full CMOS output levels help reduce power in many other
system components.
The AT22LV10 and AT22LV10L logic architectures ar e
identical to the familiar 22V10. Each output is allocated
from eight to 16 product terms, which allows highly complex logic functions to be realized.
Two additional product terms are included to provide synchronous preset an d asy nchr onous r eset . These te rms ar e
common to all ten registers. All registers are automatically
cleared upon power up.

operation of the device at these or any other conditions beyond those indicated in the operational sections of this specif ication is not implie d. Exposure to
absolute maximum rating conditions for extended
