DESCRIPTION/ORDERING INFORMATION
The TRSF3232E 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). This device 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 3-V to 5.5-V supply. The TRSF3232E operates
at data signaling rates up to 1 Mbit/s and a driver output slew rate of 14 V/μs to 150 V/μs.

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.
