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 µA 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
significantly 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 are
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 and asynchronous reset. These terms
are common to all ten registers. All registers are automati-
cally cleared upon power-up.
Register preload simplifies testing. A security fuse prevents
unauthorized copying of programmed fuse patterns.
