*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 de-

vice reliability.

Note:

1. Minimum voltage is -0.6 V dc which may undershoot to -2.0 V

for pulses of less than 20 ns. Maximum output pin voltage is

than 20 ns.

The AT22V10B incorporates a variable product term architec-

ture. Each output is allocated from eight to 16 product terms,

which allows highly complex logic functions to be realized.

The AT22V10B includes two additional product terms to pro-

vide 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 un-

authorized copying of programmed fuse patterns.
