The SN75C3221EDBR from Texas Instruments is a single-channel RS-232 transceiver designed for reliable serial communication. It operates from a single 3-V to 5.5-V supply and supports data signaling rates up to 1 Mbps.
This transceiver offers significant ESD protection for its RS-232 pins, including ±15 kV Human-body model (HBM), ±8 kV IEC 61000-4-2 contact discharge, and ±15 kV IEC 61000-4-2 air-gap discharge. It features an auto-powerdown function that automatically disables drivers for power savings when the serial port is inactive, reducing standby current to a typical 1 μA.
The SN75C3221EDBR is suitable for applications requiring robust serial interfaces, such as industrial PCs, wired networking, and battery-powered systems. It accepts 5-V logic input with a 3.3-V supply and requires four external 0.1 μF capacitors. The device is housed in a 16-SSOP package suitable for surface mounting.
Key electrical characteristics include a driver output slew rate of 24 V/μs to 150 V/μs and receiver hysteresis of 500 mV. The operating temperature range is from 0°C to 70°C.
