General Description
The MAX3388E/MAX3389E are 2.5V-powered EIA/TIA-
232 and V.28/V.24 communications interfaces with low
power requirements, high data-rate capabilities, and
enhanced electrostatic discharge (ESD) protection. The
MAX3388E/MAX3389E have two receivers and three
transmitters. All RS-232 inputs and outputs are protected
to ±15kV using the IEC 1000-4-2 Air-Gap Discharge
method, ±8kV using the IEC 1000-4-2 Contact Discharge
method, and ±15kV using the Human Body Model.
In addition to the traditional RS-232 I/O, these devices have
dedicated logic-level I/O pins for additional device-to-
device handshaking. During shutdown the logic-level I/O
pins are active for the MAX3389E. An internal 62
switch is
provided to switch power to external circuitry or modules.
A proprietary low-dropout transmitter output stage
enables RS-232 compatible performance from a +2.35V
to +3.0V supply with a dual charge pump. The charge
pump requires only four small 0.1F capacitors for oper-
ation from a +2.5V supply. The MAX3388E/MAX3389E
are capable of running at data rates up to 460kbps while
maintaining RS-232-compatible output levels.
The MAX3388E/MAX3389E have a unique VL pin that
allows interoperation in mixed-logic voltage systems.
Both input and output logic levels are pin programma-
ble through the VL pin. The MAX3388E/MAX3389E are
available in a space-saving TSSOP package.
Features
o VL Pin for Compatibility with Mixed-Voltage
Systems
o Additional I/O for Hot-Sync Applications
o ±15kV ESD Protection on Rx Inputs, Tx Outputs,
LIN, and SWIN
o Low 300A Supply Current
o Guaranteed 460kbps Data Rate
o 1A Low-Power Shutdown
o Integrated Switch for Powering Remote Circuitry
o Flow-Through Pinout
o LOUT Active During Shutdown (MAX3389E)
