Digital outputs  
1. The digital inputs of CX2833i are TTL 5 V compliant. These inputs are diode protected to DVDDIO and DVSSIO pins.  
Additionally, all of the CX2833i digital inputs contain 75 kpull-down resistors.  
2. The digital outputs of CX2833i are also TTL 5 V compliant. However, these outputs will not drive to 5 V, nor will they accept  
5 V external pull-ups. The output is DVDDC (3.3 V).
