Maxim Integrated's MAX3317EAP - 2.5V, 460kbps, RS-232 Transceivers with AutoShutdown Plus

The MAX3317EAP from Maxim Integrated is a highly efficient RS-232 transceiver module designed to operate at a low voltage of 2.5V, while providing robust communication speeds of up to 460kbps. This transceiver is an optimal solution for applications where power efficiency and space constraints are critical considerations.

Encased in a sleek 20-pin SSOP package, the MAX3317EAP is engineered with Maxim's innovative AutoShutdown Plus™ technology, which significantly reduces power consumption by entering a low-power shutdown mode when the RS-232 cable is disconnected, or the transceiver is inactive for more than 30 seconds. This feature not only conserves battery life but also extends the overall lifespan of the product.

The device integrates a dual charge pump circuitry that enables the transceiver to deliver true RS-232 performance from a single power supply ranging from +2.35V to +3.0V, making it highly versatile for various system designs. It is capable of maintaining a ±15kV ESD protection on transmitter outputs and receiver inputs, ensuring the device's resilience against electrostatic discharges, which is particularly crucial in harsh industrial environments.

With its built-in receiver hysteresis, the MAX3317EAP provides enhanced noise immunity, a feature that is particularly beneficial in noisy conditions or when long cable runs are necessary. The transceiver supports the traditional pinout of industry-standard devices, which simplifies the integration process and allows for easy upgrades in existing systems without the need for significant redesign.

Key features of the MAX3317EAP include:

• Low-Voltage Operation from +2.35V to +3.0V
• High Data Rate of up to 460kbps
• AutoShutdown Plus™ Technology for Power Conservation
• ±15kV ESD Protection on Transmitter Outputs and Receiver Inputs
• Integrated Charge Pump Circuitry
• Receiver Hysteresis for Improved Noise Immunity

Whether for portable or compact fixed applications, like PDAs, notebooks, and hand-held equipment, the MAX3317EAP is the transceiver of choice for designers looking for a reliable, low-power, and space-efficient RS-232 communication solution.
