Description
The AT22V10B is an ultra-high performance CMOS Programmable Logic Device (PLD).
Speeds down to 7.5 ns and operation up to 166 MHz are offered. All pins offer a low
10
A
leakage.
The AT22V10B logic functionality is fully compatible with the standard 22V10. The 12 dedi-
cated inputs and ten configurable I/O pins allow implementation of logic requiring up to 22
input signals. The AT22V10B also provides individual output enable product terms for each
of the ten I/Os.

*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
V
CC
+0.75 V dc which may overshoot to +7.0 V for pulses of less
than 20 ns.
Absolute Maximum Ratings*
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.
