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 soft-
ware, 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.

Absolute Maximum Ratings*
Temperature Under Bias.................................. -40°C to +85°C
*NOTICE: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age 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. Max-
imum output pin v oltage is Vcc + 0.75V dc , which
may overshoot to 7.0V for pulses of less than 20
ns.
