DESCRIPTION/ORDERING INFORMATION
The TRS3386E is a three-driver and two-receiver RS-232 interface device, with split supply pins for mixed-signal
operations. All RS-232 inputs and outputs are protected to ±15 kV using the IEC 61000-4-2 Air-Gap Discharge
method, ±8 kV using the IEC 61000-4-2 Contact Discharge method, and ±15 kV using the Human-Body Model.
The charge pump requires only four small 0.1-μF capacitors for operation from a 3.3-V supply. The TRS3386E is
capable of running at data rates up to 250 kbps, while maintaining RS-232-compliant output levels.
The TRS3386E has a unique VL pin that allows operation in mixed-logic voltage systems. Both driver in (DIN)
and receiver out (ROUT) logic levels are pin programmable through the VL pin. The TRS3386E is available in a
space-saving thin shrink small-outline package (TSSOP).

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.
V+ and V– can have maximum magnitudes of 7 V, but their absolute difference cannot exceed 13 V.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
