MAX3226EAE+T: High-Speed RS-232 Transceiver with AutoShutdown

The MAX3226EAE+T from Maxim Integrated is a high-performance, 3.0V to 5.5V powered RS-232 transceiver with a unique AutoShutdown™ feature. This device is designed to meet the demanding requirements of portable and space-constrained applications, providing reliable communication with a minimal power footprint.

Equipped with two drivers and two receivers, the MAX3226EAE+T offers a complete serial port suitable for modem and other serial interface applications. The transceiver's drivers maintain a data rate of up to 1Mbps, ensuring swift and efficient data transfer, while the receivers can handle up to 250kbps, making this component ideal for high-speed communication protocols.

One of the standout features of the MAX3226EAE+T is its AutoShutdown function, which automatically powers down the device when it does not sense a valid signal transition on the receiver inputs for 30 seconds. This innovative feature significantly reduces the power consumption of the transceiver, making it an excellent choice for battery-powered devices such as laptops, PDAs, and other portable equipment.

The MAX3226EAE+T is designed with 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 allows the device to maintain ±5.5V transmitter output levels, ensuring compatibility with a broad range of RS-232 peripherals.

Additional features of the MAX3226EAE+T include a 1µA shutdown mode, receiver hysteresis for improved noise immunity, and a guaranteed data rate even at worst-case load conditions. The device is also fully compliant with the EIA/TIA-232-F standards and operates over the extended temperature range of -40°C to +85°C.

Available in a 16-pin SSOP package, the MAX3226EAE+T is a compact and reliable solution for adding RS-232 connectivity to your designs with the added benefits of power efficiency and space-saving integration.
