Description
SP213EHCA-L is a dual RS-232 transceiver in a compact surface-mount package. It provides two drivers and two receivers to translate between TTL/CMOS UART signals and RS-232 voltage levels, enabling direct connection of microcontrollers to RS-232 serial links.
Key points:
- Single-supply operation (typical 3–5 V) with external charge-pump capacitors to generate RS-232 levels.
- Two drivers and two receivers, allowing full-duplex serial communication.
- TTL/CMOS input thresholds compatible with UART logic; RS-232 outputs swing to standard RS-232 levels.
- ESD protection on signal pins; suitable for typical serial interfaces and peripherals.
- Lead-free package option (suffix L), with a small, space-efficient footprint.
Common uses include microcontroller-to-PC/ modem connections, serial peripherals, and embedded systems needing a robust, low‑power RS-232 link. For exact electrical specs, pinout, capacitor values, and package details, consult the SP213EHCA-L datasheet from the manufacturer.
