Applications Information
Hot Insertion
SDA, SCL, AD0, AD2, and RST are overvoltage protect-
ed to +6V independent of V+. This allows the MAX7320
to be operated from a lower supply voltage, such as
+3.3V, while the I2C interface is driven from a higher
logic level, such as +5V.
Each of the output ports, O0–O7, has a protection
diode to V+ and to GND (Figure 8). When a port output
is driven to a voltage higher than V+ or lower than
GND, the appropriate protection diode clamps the out-
put to a diode drop above V+ or below GND. When the
MAX7320 is powered down (V+ = 0V), each output port
appears as a diode connected to GND (Figure 8).
Power-Supply Considerations
The MAX7320 operates with a supply voltage of +1.71V
to +5.5V over the -40°C to +125°C temperature range.
Bypass V+ to GND with a ceramic capacitor of at least
0.047F as close to the device as possible. For the TQFN
version, additionally connect the exposed pad to GND.
