8.2 Typical Application

Figure 8-1 shows an application in which the TCAL9538 can be used.

GUID-20211027-SS0I-96QJ-KPQK-SP5NPHNLRQPW-low.gif
A. Device address configured as 1110000 for this example.
B. P0, P2 and P3 are configured as outputs.
C. P1, P4, and P5 are configured as inputs.
D. Resistors are required for inputs (on P port) that may float. If a driver to an input will never let the input float, a resistor is not needed. Outputs (in the P port) do not need pullup resistors.
