MAX1608EEE+

Overview

The MAX1608EEE+ is an octal SMBus-to-parallel I/O expander manufactured by Analog Devices Inc./Maxim Integrated. It provides eight high-voltage open-drain outputs that double as TTL-level logic inputs, supporting continuous bidirectional capabilities. The device operates on a single +2.7V to +5.5V supply with a typical quiescent current of 2.5µA. It features an SMBus 2-wire serial interface and supports asynchronous suspend mode via the SMBSUS input. The component includes thermal-overload and output-overcurrent protection, with outputs low upon power-up. It is housed in a 16-pin QSOP package.

Procurement Notes

Verify the specific ordering suffix EEE against official manufacturer documentation to confirm the exact temperature range and package variant. Confirm RoHS compliance status through the latest datasheet revision. Ensure the supplier source is authorized to guarantee authenticity for this discontinued or limited-supply component.

Selection Notes

Select the MAX1608EEE+ when low power-on states are required for n-channel MOSFET load-switching applications. Verify that the system requires eight bidirectional I/O lines compatible with SMBus protocols. Ensure the operating environment falls within the specified -40°C to +85°C temperature range and voltage limits.

Part Context

This component belongs to the MAX1608/MAX1609 family of octal SMBus-to-parallel I/O expanders. The MAX1608 variant specifically powers up its outputs in a low state, distinguishing it from the MAX1609 which powers up in a high-impedance state. Both share identical pinouts and register structures but differ in initial output configuration.
