The AT22LV10L provides the optimum low power CMOS PLD solution, with low DC power (1 mA typical at VCC = 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 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 Maximum 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 conditions beyond those indicated in the operational sections 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.
