Input and I/O Pull-ups

All Atmel

®

ATF22V10B family members have internal input and I/O pull-up resistors. Therefore, whenever inputs or

I/Os are not being driven externally, they will float to V

CC

. This ensures that all logic array inputs are at known

states. These are relatively weak active pull-ups that can easily be overdriven by TTL-compatible drivers (see input

and I/O diagrams below).
