Maxim Integrated MAX3221ECAE-T RS-232 Interface IC

The MAX3221ECAE-T from Maxim Integrated is a high-performance RS-232 Interface IC designed for serial communication in various electronic applications. This device is particularly suitable for portable or space-constrained applications due to its low-power consumption and small footprint. The MAX3221ECAE-T operates from a single +3.0V to +5.5V power supply, making it versatile for use in systems with different voltage requirements.

This interface IC features an automatic shutdown function that powers down the on-chip power-supply and driver circuits when no data is transmitted or received, thus conserving power for battery-operated devices. The MAX3221ECAE-T is capable of running at data rates up to 250kbps, ensuring efficient data transfer for a wide range of communication protocols.

Designed with a 1µA low-current shutdown mode, the MAX3221ECAE-T significantly extends battery life in portable systems. Additionally, it includes a proprietary low-dropout transmitter output stage, delivering true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump. This feature allows the device to maintain ±5.5V output levels under all load conditions.

The MAX3221ECAE-T comes in a 16-pin SSOP (Shrink Small Outline Package), which is an ideal choice for applications where space is at a premium. It features a 1-driver/1-receiver configuration, and its interface standard is compliant with TIA/EIA-232-F. The device also includes a 0.1µF external capacitor, which is used in the voltage-doubling and voltage-inverting charge pumps that allow operation from a single supply.

This versatile IC is suitable for a wide range of applications, including portable computing devices, PDAs, notebooks, and other mobile communication devices where power efficiency and space are critical considerations. The MAX3221ECAE-T is a reliable solution for designers looking to implement RS-232 data interfaces with minimal power draw and maximal efficiency.

Maxim Integrated's commitment to quality ensures that the MAX3221ECAE-T meets the high standards expected for modern electronic components, providing a robust and dependable interface solution for serial communication needs.
