Frequently Asked Questions
What supply voltages does the SN75C3232EDRE4 support, and how does this affect board design?
The SN75C3232EDRE4 operates from both 3.3 V and 5 V supply rails, giving designers flexibility to integrate the IC into mixed-voltage embedded systems without level-shifting circuitry. This dual-supply compatibility covers a broad range of microcontroller and FPGA IO standards commonly used in industrial and communications designs with up to 2 EIA-232 channels.
Which interface standard does the SN75C3232EDRE4 implement, and how many channels does it provide?
The SN75C3232EDRE4 implements the EIA-232 (RS-232) interface standard with 2 driver channels and 2 receiver channels, housed in a 16-pin R-PDSO-G16 SOIC package. This makes it a dual-port solution for full-duplex serial links at typical EIA-232 data rates up to 120 kbps.
When should a designer choose the SN75C3232EDRE4 over a single-channel RS-232 transceiver?
The SN75C3232EDRE4 is the better choice when a design needs 2 independent RS-232 serial ports in a single 16-pin SOIC footprint, reducing board space and BOM count compared to using two separate single-channel devices. It is particularly valuable in embedded gateway designs that must bridge 2 serial peripherals to a host processor on a PCB with tight area constraints, operating across -40°C to +85°C.
