Description
The ATF16LV8C is a high-performanc e EECMOS Program mable Logic Devic e that
utilizes Atm el's pr oven e lectric ally er asab le Flash memory techn ology. Speeds down
to 10 ns and a 5 µA pin-controlled power down mode option are offered. All speed
ranges are specified over the full 3.0V to 5.25V range for industr ial and commercial
temperature ranges.

The ATF16LV8C incorpora tes a superse t of the gener ic
architectures, wh ich allows direct repl acemen t of the 16R8
family and most 20-pin combinatorial PLDs. Ei ght outputs
are each allocated eight produc t terms. Three different
modes of operation, configured automatically with software, allow highly complex logic functions to be realized.
The ATF16LV8C can significantly reduce total system
power, thereby enhancing system reliability and reducing

power supply costs. When pi n 4 is confi gur e d as the power
down control pin, supply current drops to less than 5 µA
whenever the pin is high. If the power down feature isn't
required for a particular application, pin 4 may be used as a
logic input. Also, the pin keeper circuits eliminate the need
for internal pull-up resistors along with their attendant
power consumption.
*NOTICE: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent damage to the dev ice . This is a s tress rating only an d
functional oper ation of the device at these o r any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions f or e xtended periods ma y af fect de vice
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 v oltage is Vcc + 0.75V dc , which
may overshoot to 7.0V for pulses of less than 20
ns.
