TRSF3232IDWG4

Drivers, Receivers, Transceivers Overview

The TRSF3232IDWG4 is a multichannel RS-232 compatible line driver and receiver manufactured by Texas Instruments. It operates from a single 3-V to 5.5-V supply and supports data rates up to 1 Mbit/s. The device integrates two line drivers, two line receivers, and a dual charge-pump circuit requiring four external capacitors. It provides ±15-kV ESD protection on bus pins and accepts 5-V logic inputs with a 3.3-V supply. The component is housed in a 16-pin SOIC (DW) package and functions within an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers FAQ

What are the recommended capacitor values for the charge pump?

For a 3.3-V supply, use 0.1 μF capacitors for C1 through C4. For a 5-V supply, use 0.047 μF for C1 and 0.33 μF for C2, C3, and C4.

Does the device support shutdown mode?

No, the TRSF3232 does not include a shutdown pin or feature; it operates continuously when powered.

How does the device handle open receiver inputs?

When the receiver input is disconnected or the driver is off, the output defaults to a high level.
