NOTE(S):

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 k

Ω pull-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).
