DESCRIPTION/ORDERING INFORMATION
The MAX202 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with
±15-kV
ESD protection pin to pin (serial-port connection pins, including GND). The device meets the requirements of
TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the
serial-port connector. The charge pump and four small external capacitors allow operation from a single 5-V
supply. The device operates at data signaling rates up to 120 kbit/s and a maximum of 30-V/µs driver output
slew rate.

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 under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltages are with respect to network GND.
Maximum power dissipation is a function of T
J
(max),
θ
JA
, and T
A
. The maximum allowable power dissipation at any allowable ambient
temperature is P
D
= (T
J
(max) – T
A
)/θ
JA
. Operating at the absolute maximum T
J
of 150°C can affect reliability.
The package thermal impedance is calculated in accordance with JESD 51-7.
