ranges are specified over the full 3.0V to 5.25V range for
industrial 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 pin 4 is configured as the
power-down control pin, supply current drops to less than
5µA 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 pu ll -up r esis to rs a lon g wi th t hei r atte nda nt
power consumption.

*NOTICE: Stresses beyond those listed under “Absolute

Maximum Ratings” may cause permanent dam­age to the device . This is a st ress rating only and
functional operatio n of the dev ice at th ese or an y
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for exten ded periods may af fect 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 Vcc + 0.75V DC,
which may overshoot to 7.0V for pulses of less
than 20 ns.

Power-up Reset

The ATF16LV8C’s registers are designed to reset during
power-up. At a point delayed slightly from V

the registered output state will always be high on power-up.
This feature is crit ical for state machine initialization.

However, due to the asynchronous nature of reset and the
uncertainty of how V

actually rises in the system, the
