What are the key features of SN65C3223EPWG4?
- Dual 2-driver/2-receiver RS-232 transceiver for full-duplex serial communication
- Schmitt trigger inputs for improved noise immunity on noisy industrial RS-232 bus lines
- Compatible with EIA-232-F, TIA-232-F, and V.28 interface standards for broad interoperability
- Also operates from 5 V supply in addition to standard 3.3 V for legacy RS-232 system support
- 20-pin TSSOP (R-PDSO-G20) compact package for dense PCB integration
What is SN65C3223EPWG4 used for?
The SN65C3223EPWG4 is used in embedded systems and industrial equipment requiring RS-232 serial communication between microcontrollers and external devices such as modems, barcode scanners, and PLCs. Its dual transmitter/receiver configuration handles two independent RS-232 channels simultaneously, supporting full-duplex point-to-point communication over standard 9-pin or 25-pin serial cables. The 5 V operational capability makes it backward-compatible with older RS-232 equipment while the 20-pin TSSOP footprint keeps board area minimal.

Frequently Asked Questions
How many RS-232 transmitter and receiver channels does SN65C3223EPWG4 provide?
SN65C3223EPWG4 provides 2 RS-232 transmitter channels and 2 RS-232 receiver channels in a single 20-pin TSSOP IC. This dual-channel configuration supports full-duplex serial communication on two independent RS-232 ports simultaneously, reducing component count compared to using two single-channel transceivers.
Why do Schmitt trigger inputs on SN65C3223EPWG4 improve reliability in industrial RS-232 applications?
Schmitt trigger inputs apply hysteresis to the receiver input threshold, typically 0.4 V or more, preventing false transitions caused by slow-rising or noisy RS-232 signals common in industrial cable runs up to 15 meters. This eliminates spurious data reception that would occur with standard comparator-type inputs in electrically noisy factory environments.
What interface standards does SN65C3223EPWG4 conform to, and what cable lengths does RS-232 typically support?
SN65C3223EPWG4 conforms to EIA-232-F, TIA-232-F, and V.28 serial interface standards, which define signal levels of ±5 V to ±15 V output swing and support cable lengths up to 15 meters at data rates up to 20 kbps, or shorter distances at higher baud rates such as 115200 bps.
When is SN65C3223EPWG4 a suitable alternative to a 5 V-only RS-232 transceiver in a mixed-voltage design?
SN65C3223EPWG4 supports both 3.3 V and 5 V supply operation, making it ideal for mixed-voltage designs where a 3.3 V microcontroller must communicate with a 5 V legacy RS-232 peripheral. Switching to a 3.3 V-compatible transceiver eliminates the need for a separate 5 V logic level shifter, reducing BOM cost and shrinking the PCB footprint by removing 1 to 2 additional ICs.
