PCA9672
Remote 8-bit I/O expander for Fm+ I
2
C-bus with interrupt and reset
PCA9670 replaces the interrupt output of the PCA9674 with hardware reset input to retain
the maximum number of addresses. The PCA9672 replaces address A2 of the PCA9674
with hardware reset input to retain the interrupt, but limit the number of addresses.
