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 A 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. Block Diagram Note: 1. Includes optional PD control pin.

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. 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.

This parameter is only sampled and is not 100% tested. Power Up Reset The ATF16LV8C's registers are designed to reset during power up. At a point delayed slightly from V CC crossing VRST, all registers will be reset to the low state. As a result, the registered output state will always be high on power-up. This feature is critical for state machine initialization. However, due to the asynchronous nature of reset and the uncertainty of how VCC actually rises in the system, the following conditions are required: 1. The VCC rise must be monotonic from below 0.7 volts. 2. The signals from which the clock is derived must remain stable during TPR. 3. After TPR, all input and feedback setup times must be met before driving the clock term high.
