1. Description
The ATF16V8B is a high-performance CMOS (electricallyerasable) programmable
logic device (PLD) that utilizes Atmel’s proven electrically-erasable Flash memory
technology. All speed ranges are specified over the full 5V
±
10% range for industrial
temperature ranges, and 5V
±
5% for commercial temperature ranges.
Several low-power options allow selection of the best solution for various types of
power-limited applications. Each of these options significantly reduces total system
power and enhances system reliability.
The ATF16V8Bs incorporate a superset of the generic architectures, which allows
direct replacement of the 16R8 family and most 20-pin combinatorial PLDs. Eight out-
puts are each allocated eight product terms. Three different modes of operation,
configured automatically with software, allow highly complex logic functions to be
realized.

*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age 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, which may under-
shoot to -2.0V for pulses of less than 20 ns.
Maximum output pin voltage is V

+ 0.75V DC,
which may overshoot to 7.0V for pulses of less
