Port Supplies and Level Translation
The MAX7307 features a port supply, V LA , that provides
the logic supplies to all push-pull I/O ports. P2 through
P4 can be configured as push-pull I/O ports (see Figure
3). V LA powers the logic-high port output voltage sourc-
ing the logic-high port load current. V LA provides level
translation capability for the outputs and operates over a
1.40V to 5.5V voltage independent of the power-supply
voltage, V DD .
Each port of the MAX7307 set as an input can be config-
ured to switch midrail of either the V DD or the V LA port
supplies. Whenever the port supply reference is
changed from V DD to V LA , or vice versa, read the port
register to clear any transition flag on the port.
Ports P2 through P4 are overvoltage protected to V LA .
This is true even for a port used as an input with a V DD
port logic-input threshold. Port P1 is overvoltage pro-
tected to 5.5V, independent of V DD and V LA (see Figure
3). To mix logic outputs with more than one voltage
swing on a group of ports using the same port supply,
set the port supply voltage (V LA ) to be the highest out-
put voltage. Use push-pull outputs and port P1 for the
highest voltage ports, and use open-drain outputs with
external pullup resistors for the lower voltage ports. For
the MAX7307, when P2, P3, and P4 ports are acting as
an input referenced to V DD, make sure the V LA voltage
is greater than V DD - 0.3V.
