Description
The AT22V10 and AT22V10L are CMOS high performance EPROM-based Program-
mable Logic Devices (PLDs). Speeds down to 15 ns and power dissipation as low as
12 mA are offered. All speed ranges are specified over the full 5 V
±10%
range. All
pins offer a low
±10 µA
leakage.
The AT22V10L provides the optimum low power CMOS PLD solution, with low DC
power (8 mA typical) and full CMOS output levels. The AT22V10L significantly re-
duces total system power and enhances system reliability.
Full CMOS output levels help reduce power in many other system components.
The AT22V10 and AT22V10L incorporate a variable product term architecture. Each
output is allocated from eight to 16 product terms, which allows highly complex logic
functions to be realized.

Description
(Continued)
Two additional product terms are included to provide syn-
chronous preset and asynchronous reset. These terms
are common to all 10 registers. All registers are automat-
ically cleared upon power up.
Register preload simplifies testing. A security fuse pre-
vents unauthorized copying of programmed fuse patterns.

*NOTICE: Stresses beyond those listed under “Absolute Maxi-
mum 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 indi-
cated 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 -0.6 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.
