ATF16LV8C 2 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 soft- ware, 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 m 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. absolute maximum ratings* temperature under bias.................................. -40c to +85c *notice: stresses beyond those listed under absolute maximum ratings may cause permanent dam- age 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 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. storage temperature ..................................... -65c to +150c voltage on any pin with respect to ground .........................................-2.0v to +7.0v (1) voltage on input pins with respect to ground during programming.....................................-2.0v to +14.0v (1) programming voltage with respect to ground .......................................-2.0v to +14.0v (1) dc and ac operating conditions commercial operating temperature (ambient) 0 c - 70 c v cc power supply 3.0v to 5.5v

ATF16LV8C 5 input test waveforms and measurement levels: t r , t f < 1.5ns (10% to 90%) output test loads: commercial note: similar devices are tested with slightly different loads. these load differences may affect output signals delay and slew rate. atmel devices are tested with sufficient margins to meet compatible devices. note: 1. typical values for nominal supply voltage. this parameter is only sampled and is not 100% tested. power-up reset the ATF16LV8Cs registers are designed to reset during power-up. at a point delayed slightly from v cc crossing v rst , 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 v cc actually rises in the system, the following conditions are required: 1. the v cc rise must be monotonic from below 0.7v. 2. the signals from which the clock is derived must remain stable during t pr . 3. after t pr , all input and feedback setup times must be met before driving the clock term high. output pin 3.3v cl = 35 pf r1 = 316 r2 = 348 pin capacitance (f = 1 mhz, t = 25c) (1) typ max units conditions c in 58 pfv in = 0v c out 68 pfv out = 0v parameter description typ max units t pr power-up reset time 600 1,000 ns v rst power-up reset voltage 2.5 3.0 v
