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