3 ATF16LV8C2ranges are specified over the full to range forindustrial and commercial temperature ATF16LV8C incorporates a superset of the genericarchitectures, which allows direct replacement of the 16R8family and most 20-pin combinatorial PLDs. Eight outputsare each allocated eight product terms. Three differentmodes of operation, configured automatically with soft-ware, allow highly complex logic functions to be ATF16LV8C can significantly reduce total systempower, thereby enhancing system reliability and reducingpower supply costs. When pin 4 is configured as thepower-down control pin, supply current drops to less than5 A whenever the pin is high.

4 If the power-down featureisn't required for a particular application, pin 4 may be usedas a logic input. Also, the pin keeper circuits eliminate theneed for internal pull-up resistors along with their attendantpower DiagramNote:1.

This parameter is only sampled and is not 100% ResetThe ATF16LV8C s registers are designed to reset duringpower-up. At a point delayed slightly from VCC crossingVRST, all registers will be reset to the low state. As a result,the registered output state will always be high on feature is critical for state machine , due to the asynchronous nature of reset and theuncertainty of how VCC actually rises in the system, thefollowing conditions are required:1.
