Overview

Description

ST3243ECTR-E is an RS-232 transceiver IC from STMicroelectronics. It serves as the interface between a microcontroller’s logic UART and RS-232 level signals, converting TTL/CMOS data to RS-232 voltages and vice versa. The device typically includes an on-chip charge pump to generate the required RS-232 swing from a single supply, enabling simple, low‑power serial links. The -ECTR suffix indicates an extended‑temperature variant (and packaging/tape‑reel options). It’s used in embedded systems, industrial equipment, and any application needing reliable TTL-to-RS-232 conversion. For exact specs (channels, supply voltage, data rate, pinout, and packaging), refer to the official ST3243ECTR-E datasheet on STMicroelectronics’ website.

Features

ST3243ECTR-E is an RS-232 transceiver family device. Key features:
- Single-supply operation: 3.0 V to 5.5 V
- External charge-pump capacitors for RS-232 level generation
- Two drivers and two receivers (dual RS-232 transceiver)
- TTL/CMOS-compatible logic inputs; RS-232 compliant outputs
- Data rate up to ~1 Mbit/s
- RS-232 output swing typically ±6 V to ±10 V
- Protections: undervoltage lockout, thermal shutdown, short-circuit protection
- ESD protection on all I/O
- RoHS-compliant, available in 16-pin package
- Industrial operating temp range (typical -40°C to +85°C)
Note: exact channel count and package variants may vary by specific ordering code; consult the datasheet for precise specifications.

Package

16-pin Small Outline IC (SOIC-16) package. Tape-and-Reel option with Pb-free (lead-free) variant.

Pinout

Pin count: 20 pins (20-pin package).
Function: ST3243ECTR-E is a quad RS-232 transceiver (four drivers and four receivers). It provides level shifting between TTL/CMOS logic and RS-232 voltage levels, using an internal charge pump to generate the required RS-232 voltages from a single supply.

Manufacturer

- Manufacturer: STMicroelectronics (ST).
- What kind of company: A global, Franco‑Italian multinational semiconductor company that designs, manufactures, and sells integrated circuits and discrete electronic components.

Application

ST3243ECTR-E is a quad EIA/TIA-232 RS-232 transceiver. It’s used to implement RS-232 interfaces in embedded systems and microcontroller projects, converting TTL/CMOS UART signals to RS-232 levels. Common applications include PC peripherals and printers, industrial equipment and PLCs, modems and networking gear, data loggers, test/measurement equipment, POS terminals, and any device needing short-to-medium distance RS-232 serial links.
