Description

SP3223EEY-L/TR is a dual RS-232 transceiver (two drivers and two receivers) designed to connect a microcontroller or microprocessor to RS-232 serial ports. It translates TTL/CMOS logic levels to RS-232 voltage swings and vice versa, using an internal charge-pump that requires external capacitors.
Key points:
- One-supply operation (typical 3.0–5.5 V; check datasheet for exact range)
- 2 RS-232 drivers and 2 RS-232 receivers
- Generates RS-232 levels (± voltages) from a single supply
- External charge-pump capacitors required
- Lead-free, Tape & Reel package (EEY-L/TR suffix)
Typical use cases: embedded serial interfaces, microcontroller-based PCs, data loggers, POS devices, USB-to-serial adapters.
Why choose: low pin count (8-pin package), integrated level shifting, suitable for space- and power-constrained designs.
Note: exact voltage range, data rate, pinout, and capacitor values vary by variant—consult the official datasheet for SP3223EEY-L/TR to confirm specs and application circuits.

Features

SP3223EEY-L/TR is a 2-channel RS-232 transceiver. Key features:
- 2 drivers + 2 receivers (2/2)
- Single-supply operation: 3.0 V to 5.5 V
- On-chip charge pump (external capacitors required) to generate RS-232 levels
- RS-232 compatible signaling between microcontrollers and serial devices
- Data rates suitable for standard RS-232; typical up to 1 Mbps
- TTL/CMOS-compatible input thresholds
- Low power operation with optional low-power/shutdown modes
- Robust protection: ESD protection on all pins
- Packaging: 8-pin package; RoHS-compliant; -L/TR indicates lead-free, tape-and-reel version
- Temperature variants available (commercial/extended as applicable)
Note: External charge-pump capacitors are required for RS-232 level generation.

Package

8-pin SOIC package (lead-free), shipped in Tape-and-Reel (TR).

Pinout

- Pin count: 8 pins (SOIC-8).
- Function: a single-channel RS-232 transceiver (one driver and one receiver) that converts TTL/CMOS logic to RS-232 levels and RS-232 levels back to TTL/CMOS. Typically powered from 3.3–5.5 V and uses an internal charge-pump to generate RS-232 voltages. The -L/TR denotes lead-free, tape-and-reel packaging.

Manufacturer

Manufacturer: Exar Corporation (originally Sipex; now part of MaxLinear).
What kind of company: A semiconductor company that designs and manufactures analog and mixed-signal integrated circuits.

Application

SP3223EEY-L/TR is a low‑power 3.3 V RS-232 transceiver (line driver/receiver). Applications: interface microcontrollers/SoCs to RS-232 devices; used in PCs/modems, printers, routers/network gear, POS terminals, industrial controllers, data loggers, telemetry systems, GPS modules, and medical instrumentation.

Equivalent

SP3223EEY-L/TR is a Sipex RS-232 transceiver. Common cross-refs (RS-232 transceivers, similar voltage range) include:
- MAX3223E / MAX3232E (Maxim)
- ADM3223 / ADM3232 (Analog Devices)
- SP3232E / SP3232 (Exar/MaxLinear)
Note: verify channel count (drivers/receivers) and supply voltage (3.3V–5V) and package before replacement.
