MAX3311/MAX3313
19-1901; Rev 0; 2/01
460kbps, 1A Supply Current,
RS-232-Compatible Transceivers in MAX
General Description Features
The MAX3311/MAX3313 are low-power, +5V EIA/TIA-
1A Low-Power Shutdown (MAX3311)
232-compatible transceivers. Both devices have one
INVALID Output (MAX3313)
transmitter and one receiver. The transceivers have a
proprietary low-dropout transmitter output stage
Receiver Active in Shutdown (MAX3311)
enabling RS-232-compatible operation from a +5V sup-
Single Transceiver (1Tx/1Rx) in 10-Pin MAX
ply with a single inverting charge pump. These devices
require only three 0.1F capacitors and will run at data
RS-232-Compatible Operation
rates up to 460kbps while maintaining RS-232-compati-
ble output levels.
The MAX3311 features a 1A 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.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
