The MAX3245EETX+ is a high-performance, 3.0V to 5.5V, low-power, up to 1Mbps, true RS-232 transceiver from Maxim Integrated, designed to meet the stringent requirements of battery-powered applications. This transceiver features a proprietary low-dropout transmitter output stage, providing true RS-232 performance from a 3.0V to 5.5V supply with a dual charge pump.
The device is equipped with an AutoShutdown Plus™ feature that automatically enters a low-power shutdown mode when the RS-232 cable is disconnected, or the transmitters of the connected peripherals are off, significantly reducing power consumption. The MAX3245EETX+ is capable of achieving 1µA supply current in shutdown mode, making it an ideal choice for power-sensitive applications.
This transceiver has a wide range of applications, including battery-powered equipment, notebooks, laptops, palmtop computers, and handheld equipment, where power efficiency is a critical aspect. The MAX3245EETX+ supports data rates up to 1Mbps and includes a 1µF external charge pump capacitor, which minimizes the required board space and component count.
The MAX3245EETX+ comes in a 36-pin TSSOP package, which is suitable for space-constrained applications. It features a 2-driver/2-receiver configuration, providing a robust serial communication interface. The device is fully compliant with TIA/EIA-232-F standards and ensures reliable data transmission even in harsh environments.
Key features of the MAX3245EETX+ include:
- 3.0V to 5.5V Single Supply Operation
- 1Mbps Data Rate
- AutoShutdown Plus™ Feature for Low Power Consumption
- 1µA Low Shutdown Current
- True RS-232 Transceiver with Low-Dropout Transmitter Output Stage
- Small 36-pin TSSOP Package
Overall, the MAX3245EETX+ from Maxim Integrated is a versatile and efficient solution for designers looking to incorporate RS-232 communication capabilities into their power-sensitive applications without compromising on performance.
