strength?



Problem Description:
Keywords: external pullup, drive, I/O

Urgency: standard

General Description: Can an External Pullup be used to increase the
output drive strength of a 9500 part with VccIO=3.3V?


Solution 1:

You could use an External Pullup to increase the output drive strength
to 5V. Use a resistance 1Kohm or larger. Trying to pull up the drive
strength to anything more than 5V will get clamped down to 5V.
