PC8260 PowerQUICC II

2131B–HIREL–02/03

The forward voltage should be effective at the current levels needed by the processor,

approximately 2-3 amps. That is, do not use diodes with only a nominal V

F which drops

too low at high current.

Recommended Operating

Conditions

Note:

The recommended and tested operating conditions. Proper device operation outside of

these conditions is not guaranteed.

This device contains circuitry to protect against damage due to high static voltage or

electrical fields. However, it is advised that normal precautions be taken to avoid appli-

cation of any voltages higher than maximum-rated voltages to this high-impedance

circuit. Operational reliability is enhanced if unused inputs are tied to an appropriate

logic voltage level (either GND or V

CC).

Notes:

1. Assumes a single layer board with no thermal bias

2. Natural convection

3. Assumes a four layer board
