• Category: Interface - I/O Expanders
• Package: 24-TSSOP
• Operating Temperature Range: -40°C to +85°C
• Supply Voltage (VCC): 1.65V to 5.5V
• Number of I/O Ports: 16
• Interface Type: I²C, SMBus
• Clock Frequency: Up to 400kHz
• Interrupt Output: Yes
• Current Consumption (Standby): 1µA (typical)

Descriptions:

The MAX7311AUG+T is a low-voltage, 16-bit I²C/SMBus I/O expander with interrupt output and internal pull-up resistors. It provides remote I/O expansion for microcontrollers via the I²C serial interface. Each of the 16 I/O pins can be independently configured as an input or output.

Features:

• 16 Programmable I/O Pins: Configurable as inputs or outputs.
• Wide Voltage Range: Operates from 1.65V to 5.5V, compatible with low-voltage systems.
• I²C/SMBus Interface: Supports standard (100kHz) and fast (400kHz) modes.
• Interrupt Output: Alerts the host of input changes without polling.
• Internal Pull-Up Resistors: Eliminates the need for external resistors.
• Low Standby Current: 1µA (typical) for power-sensitive applications.
• Industrial Temperature Range: -40°C to +85°C.
