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.
