Description
The AT22V10 and AT22V10L are CMOS high performance EPROM-based Programmable
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 reduces total sys-
tem 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.
Two additional product terms are included to provide synchronous preset and asynchronous
reset. These terms are common to all 10 registers. All registers are automatically cleared upon
power up.
Register preload simplifies testing. A security fuse prevents unauthorized copying of pro-
grammed 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 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.
