MAX3311

460kbps, 1µA Supply Current, RS-232-Compatible Transceivers in µMAX

Save Board Space with a ±15kV ESD-Protected RS-232 Transceiver in a uMAX Package


Please check latest availability status for a specific part variant.

Description

The MAX3311/MAX3313 are low-power, +5V EIA/TIA-232-compatible transceivers. Both devices have one transmitter and one receiver. The transceivers have a proprietary low-dropout transmitter output stage enabling RS-232-compatible operation from a +5V supply with a single inverting charge pump. These devices require only three 0.1µF capacitors and will run at data rates up to 460kbps while maintaining RS-232-compatible output levels.

The MAX3311 features a 1µA shutdown mode. In shutdown the device turns off the charge pump, pulls V- to ground, and the transmitter output is disabled. The MAX3313 features an active-low INVALID output that asserts high when an active RS-232 cable signal is connected, signaling to the host that a peripheral is connected to the communication port.
