Description

The AT22LV10 and AT22LV10 L are low-vo lta ge compatible CMOS high-per forma nc e
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 low DC
power (1 mA typical at V

= 3.3V) and full CMOS output levels. The AT22LV10L

CC

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, whi ch 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 automati­cally cleared upon power-up.
