ATF16LV8C General Description
The ATF16LV8C is a high-performance EECMOS Programmable Logic Device that utilizes Atmel's proven electrically erasable Flash memory technology. Speeds down to 10 ns and a 5 A pin-controlled power down mode option are offered. All speed ranges are specified over the full 3.0V to 5.25V range for industrial and commercial temperature ranges.
The ATF16LV8C incorporates a superset of the generic architectures, which allows direct replacement of the 16R8 family and most 20-pin combinatorial PLDs. Eight outputs are each allocated eight product 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 5 mA 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 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 undershoot 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.
