Maxim Integrated MAX1489EEPD+ Product Overview

The MAX1489EEPD+ from Maxim Integrated is a high-performance, low-power, quad RS-232 line receiver designed to meet the stringent requirements of EIA/TIA-232 communication standards. This device is particularly suitable for applications where space is at a premium and low power consumption is essential, such as in battery-powered devices, portable instruments, and compact industrial equipment.

With its integrated charge pump circuitry, the MAX1489EEPD+ eliminates the need for external components to generate the necessary RS-232 voltage levels, thereby reducing board space and simplifying design. The charge pump requires only four small 0.1µF capacitors, which contributes to the compact footprint of the overall design.

The MAX1489EEPD+ operates from a single +5V power supply, making it compatible with standard digital logic levels. Its receivers can handle up to ±30V input levels, providing robust protection against line-voltage spikes and surges, ensuring reliable data communication even in harsh electrical environments.

Each of the four receivers in the MAX1489EEPD+ features a three-state output, which allows for direct connection to data buses and multiplexed systems. The device also features a low-power shutdown mode that reduces power consumption to a mere 1µW, further extending battery life in portable applications.

The MAX1489EEPD+ is available in a 14-pin plastic DIP package, making it easy to integrate into a wide range of designs. Its operating temperature range of -40°C to +85°C ensures that the device can perform reliably in extreme conditions, suitable for industrial-grade applications.

Key features of the MAX1489EEPD+ include:

• Meets EIA/TIA-232 specifications
• Low-power operation
• Integrated charge pump circuitry
• ±30V receiver input levels
• Three-state receiver outputs
• Low-power shutdown mode
