Number of channels

32 IO in 4 Banks configurable as inputs or outputs  Bank1 : D0-7    Bank2 : D8-15   Bank3 : D16-23     Bank4 : D24-31

VUser1 for Bank 1 and 2      VUser2 for Bank 3 and 4


Input impedance

> 100 kOhm

Reverse voltage protection


Maximum  voltage protection

+/- 50 Volts

Detection threshold

4 programmable Schmitt trigger level step 0.118V from 0.470V to 29.4V threshold high and threshold low for each bank

Recommended levels threshold

The default thresholds are LOW = 1.5V, HIGH = 3.5V.

To improve noise immunity, a LOW level threshold of 1/3 VUser and a HIGH level threshold of 2/3 VUser are recommended.
