PERIPHERAL INTERFACE ADAPTER

Features

* FIGURE 13 - INTERRUPT PULSE WIDTH AND IRQ RESPONSE
* Assumes part was deselected during any previous E pulse.
* Assumes Interrupt Enable Bits are set. Note: Timing measurements are referenced to and from a low voltage of 0.8 volts and a high voltage of 2.0 volts, unless otherwise noted

Applications

* of any voltage higher than maximum rated voltages to this highimpedance circuit. For proper operation it is recommended that Vin and Vout be constrained to the range GNDs(Vin or Voutl :S VCC. Unused inputs must always be tied to an appropriate logic voltage level (e. g. , either GND or Vccl. POWER CO
