The MAX7320 2-wire serial-interfaced peripheral fea-
tures eight push-pull outputs with selectable power-up
logic states.
The +5.5V tolerant RST input clears the serial interface,
terminating any I
MAX7320.
The MAX7320 uses two address inputs with four-level
logic to allow 16 I
address also determines the power-up state level for
the outputs in groups of four ports.
The MAX7320 supports hot insertion. The serial inter-
face SDA, SCL, AD0, AD2, and RST remain high
impedance in power-down (V+ = 0V) with up to +6V
asserted on them.
The MAX7320 is one device in a family of pin-compatible
port expanders with a choice of input ports, open-drain
I/O ports, and push-pull output ports (see Table 1).
The MAX7320 is available in 16-pin QSOP and 16-pin
TQFN packages, and is specified over the automotive
temperature range (-40°C to +125°C).
