MAX7328/MAX7329

I C Port Expanders with Eight I/O Ports

General Description

The MAX7328/MAX7329 are 2-wire serial-interfaced

peripherals with eight I/O ports. Any port can be used as

a logic input or an open-drain output.

Features

● 100kHz, 5.5V-Tolerant, I C-Compatible Serial

Interface

● 2.5V to 5.5V Operating Supply Voltage Range

● Low-Standby-Current Consumption of 10μA (max)

All input ports are continuously monitored for state chang-

es (transition detection). Transitions are alerted through

the open-drain, 5.5V-tolerant INT output.

● I C Bus-to-Parallel-Port Expander

● Open-Drain Interrupt Output INT

● 8-Bit Remote I/O Port for the I C Bus

The MAX7328 and MAX7329 versions differ only by their

slave ID address ranges. The MAX7328 has a slave ID

range of 0100xxx (0x20 to 0x27). The MAX7329 has a

slave ID range of 0111xxx (0x38 to 0x3F).

● Latched Outputs with High-Current-Drive Capability

for Directly Driving LEDs

● Address by Three Hardware Address Pins for Use of

Up to Eight Devices (Up to 16 Using Both MAX7328/

MAX7329)

For a similar part with overvoltage-protected I/Os and a

bus RST input that clears the I C serial interface, refer to

the MAX7321 data sheet. The MAX7328/MAX7329 are

members of a family of pin-compatible port expanders

with a choice of input ports, open-drain I/O ports, and

push-pull output ports (see the Selector Guide).
