Key Features
- Dual-channel RS-232 line driver and receiver in a single package enables full-duplex serial communication with minimal component count
- Operates from 3V to 5.5V single supply with internal charge pump, eliminating need for external ±12V rails
- Schmitt-trigger receiver inputs provide noise-immune signal conditioning for robust operation in noisy industrial environments
- Supports up to 1 Mbps data rate for high-speed serial communication applications beyond standard RS-232 speeds
Applications
The SN65C3232EDE4 is designed for UART-to-RS-232 level translation in microcontroller and processor-based systems requiring serial port connectivity to legacy RS-232 equipment. It suits industrial automation controllers, embedded system serial consoles, and telecommunication equipment where single-supply RS-232 transceiver operation at 3.3V or 5V is required. Network infrastructure, test instrumentation, and point-of-sale terminals also benefit from its dual-channel full-duplex configuration.

Frequently Asked Questions
What supply voltage does the SN65C3232EDE4 support?
The SN65C3232EDE4 operates from a 3V to 5.5V single supply, making it compatible with both 3.3V and 5V logic systems. Internal charge pumps generate the RS-232 compliant ±5V or higher output voltage levels without external voltage rails.
How many RS-232 channels does the SN65C3232EDE4 have?
The SN65C3232EDE4 provides two driver channels and two receiver channels, enabling full-duplex RS-232 communication over a standard DB-9 serial interface. Each receiver uses Schmitt-trigger inputs for improved noise immunity in real-world environments.
What is the maximum data rate of the SN65C3232EDE4?
The SN65C3232EDE4 supports data rates up to 1 Mbps, significantly exceeding the traditional 115.2 kbps RS-232 limit. This allows its use in high-speed serial communication scenarios such as firmware update interfaces and industrial protocol bridges.
What package does the SN65C3232EDE4 use?
The SN65C3232EDE4 is housed in a 16-pin SOIC surface-mount package with JEDEC code R-PDSO-G16. It is lead-free (RoHS-compliant) and compatible with standard automated SMD assembly processes across volume production runs.
What are typical applications for the SN65C3232EDE4?
Typical applications include microcontroller UART to RS-232 conversion, industrial PLC serial interfaces, embedded system debug consoles, legacy serial printer or modem interfacing, and any system requiring single-supply RS-232 level translation with dual full-duplex channels.
