VCC = 4.5V and 5.5V unless otherwise specified. CLK loading: CL = 100pF. 2. With the internal crystal oscillator using recommended crystal and capacitive loading; or with the EFI input meeting specifications t1 and t2. The recommended crystal loading for CLK frequencies of 8MHz to 20MHz are 25pF from pin X1 to ground, and 15pF from pin X2 to ground; for CLK frequencies from 20MHz to 25MHz the recommended loading is 15pF from pin X1 to GND. These recommended values are +5pF and include all stray capacitance. Decouple VCC and GND as close to the 82C284 as possible. 3. This is an asynchronous input. This specification is given for testing purposes only, to assure recognition at a specific CLK edge. 4. The pull-up resistor value for the READY pin is 620 Ω with the rated 150pF load. 5. t16 refers to any allowable CLK period. 6. When using a crystal with the recommended capacitive loading, CLK output HIGH and LOW times are guaranteed to meet 80C286 re- quirements. 7. Measured from 1.0V on the CLK to 0.8V on the RES waveform for RES waveform for RES active and to 4.2V on the RES waveform for RES inactive. 8. Input test waveform characteristics: VIL = 0V, VlH = 4.5V. AC Electrical Specifications TA = 0 oC to +70oC (CD82C284); V CC = 5V ±10% (Continued) TA = -40 oC to +85oC (lD82C284) AC Timings are Referenced to 0.8V and 2.0V Points of the Signals as Illustrated in Waveforms, Unless Otherwise Noted.
