SP330EEY-L/TR [MAXLINEAR]

The SP330 is an advanced multiprotocol transceiver supporting RS-232, RS-485, and RS-422 serial standards. It features a variable low voltage logic interface down to 1.65V, operates from a single supply (3.3V or 5V), and requires only four external charge pump capacitors. It supports high-speed data rates up to 20Mbps for RS-485/422 and 1Mbps for RS-232, with pin-selectable slew limiting to minimize EMI. The device includes robust ESD protection (±15kV IEC 61000-4-2 Air Gap, ±8kV Contact, ±15kV HBM) and receiver fail-safe protection for open, shorted, or terminated inputs. It operates in half or full duplex modes and can support up to 256 receivers on a bus with 1/8th unit load.
