Input and I/O Pull-ups

All Atmel® ATF22V10CZ/CQZ family members have internal input and I/O pin-keeper circuits. Therefore, whenever

inputs or I/Os are not being driven externally, they will maintain their last driven state. This ensures that all logic

array inputs and device outputs are at known states. These are relatively weak active circuits that can be easily

overridden by TTL-compatible drivers (see input and I/O diagrams below).
