XC1700D: Driving inputs when VCC is down should be avoided

Description

Inputs

General Description: Are there any concerns with driving

the inputs when VCC is down on the XC1700 proms?

解决方案

The inputs on the XC1700 proms have protection diodes.

Driving the inputs when VCC is down will activate the

diodes and can result in large currents. Prolonged

exposure to these currents can result in metal migration

and reliability issues.
