Key Features

  • Two-channel RS-232 transceiver with Schmitt trigger inputs providing noise immunity on data lines
  • Operates from 3V to 5.5V supply, compatible with both 3.3V and 5V logic systems in a single design
  • Compact 16-pin SSOP package with EIA-232 compliance for reliable serial communication in space-constrained boards

Applications

The SN65C3232EDBG4 is used in embedded systems and industrial equipment requiring RS-232 serial ports with 3.3V or 5V logic compatibility. It is ideal for microcontroller UART bridges, PLC serial interfaces, and portable data acquisition instruments where low supply voltage and EIA-232 compliance are both required.

Frequently Asked Questions

What is the driver and receiver channel count in SN65C3232EDBG4 and which interface standard does it comply with?

The SN65C3232EDBG4 integrates 2 RS-232 drivers and 2 receivers in a 16-pin SSOP package, fully compliant with the EIA-232 interface standard. Each receiver includes Schmitt trigger inputs for noise rejection, and the part supports data rates typical for RS-232 serial communication up to 120 kbps, making it reliable for embedded UART-to-serial bridges.

Can SN65C3232EDBG4 operate from a 3.3V rail, and what is its full supply voltage tolerance?

Yes, the SN65C3232EDBG4 operates across a supply voltage range of 3V to 5.5V, supporting both 3.3V and 5V systems. This broad input range makes it a versatile choice for mixed-voltage designs. The part generates RS-232-compliant output voltage levels from a low 3V supply, eliminating the need for a separate 5V rail in 3.3V-only battery-powered or embedded systems.

When should a designer choose SN65C3232EDBG4 over a higher channel-count RS-232 transceiver?

SN65C3232EDBG4 is appropriate when only 2 serial channels are needed and board space is limited, since its 16-pin SSOP footprint is smaller than 20-pin or 28-pin alternatives offering more channels. It is also cost-effective for designs with a single UART port plus one auxiliary serial port, such as a GPS module and a debug console sharing the same 3.3V power supply rail.
