When pin 4 is configured as the The ATF16LV8C incorporates a superset of the generic power-down control pin, supply current drops to less than architectures, which allows direct replacement of the 16R8 5 A whenever the pin is high. If the power-down feature family and most 20-pin combinatorial PLDs. Eight outputs isn t required for a particular application, pin 4 may be used are each allocated eight product terms.
