Overview
19-1910; Rev 0; 1/01 ±15kV ESD-Protected, 460kbps, 1µA, RS-232-Compatible Transceivers in µMAX General Description The MAX3311E/MAX3313E are low-power, 5V EIA/TIA232-compatible transceivers.
All transmitter outputs and receiver inputs are protected to ±15kV using the Human Body Model, making these devices ideal for applications where more robust transceivers are required.
Both devices have one transmitter and one receiver.
The transmitters have a proprietary low-dropout transmitter output stage enabling RS-232-compatible operation from a +5V supply with a single inverting charge pump.
These transceivers require only three 0.
1µF capacitors and will run at data rates up to 460kbps while maintaining RS-232-compatible output levels.
The MAX3311E 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 MAX3313E features an 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.
