Simplified Diagram of TT002 GPIO Circuit
Figure 3-38 Simplified TT002 GPO and GPI circuits
The voltage input range for the TT002 GPI is 0 to 2.5 volts DC for a valid logic
“low”, and 2.5 volts to 5 volts DC for a valid logic “high”. Input pins can be ground-
ed via an open collector, relay, open drain, etc. to change from a high to low logic
state.
