7.0 Electrical/Mechanical Specifications
7.1 Interfacing the RC224ATLV
The RC224ATLV is not 5.0 V I/O logic tolerant. It is recommended that a series
resistor of 150 Ω be added to current limit the digital inputs to the RC224ATLV
when interfacing to + 5.0 V logic output lines. The digital outputs of the
RC224ATLV should not go to resistor pullups that are connected to the + 5 V
power supply. These precautions will help prevent the modem chip from going
into latchup due to raising any input or output pin level more than + 0.3 V above
the + 3.3 V power rail of the RC224ATLV.
7.2 Environmental Requirements
The environmental specifications are listed in Table 7-1.
