The MAX3311E/MAX3313E are low-power, 5V EIA/TIA-
232-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 trans-
mitter output stage enabling RS-232-compatible opera-
tion 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.
