N.C.
No Connection. Not internally connected.
Margin Input. Configure MARGIN to either assert PO_ into a programmed state or to hold
11
11
MARGIN
PO_ in its existing state when driving MARGIN low (see Table 7). Leave MARGIN
unconnected or connect to DBP if unused. MARGIN overrides MR if both assert at the
same time. MARGIN is internally pulled up to DBP through a 10μA current source.
Manual Reset Input. Configure MR to either assert PO_ into a programmed state or to have
12
12
MR
no effect on PO_ when driving MR low (see Table 6). Leave MR unconnected or connect
to DBP if unused. MR is internally pulled up to DBP through a 10μA current source.

Serial Data Input/Output (Open-Drain). SDA requires an external pullup resistor.
Serial Clock Input. SCL requires an external pullup resistor.
Address Input 0. Address inputs allow up to four MAX6872/MAX6873 connections on one
common bus. Connect A0 to GND or to the serial interface power supply.
Address Input 1. Address inputs allow up to four MAX6872/MAX6873 connections on one
common bus. Connect A1 to GND or to the serial interface power supply.
