Présentation

Description

SP3223EEY-L/TR is a single-channel RS-232 transceiver from Sipex/Exar. It translates UART signals from a microcontroller (TTL/CMOS levels) to RS-232 voltage levels and, in the opposite direction, RS-232 signals back to TTL/CMOS. The device uses an on‑chip charge pump to generate the required RS-232 voltages from a single supply (3.0–5.5 V). Typical data rate support is in the Mbps range, suitable for standard UART interfaces, with low quiescent current. The “L” indicates a lead-free package, and “/TR” denotes Tape-and-Reel packaging. Common applications include microcontroller to PC serial ports, embedded serial links, modems, and other RS-232 interfacing tasks.

Equivalent

Equivalent products (dual RS-232 transceivers):
- Maxim MAX3223E
- Analog Devices ADM3223 / ADM3222
- STMicroelectronics ST3232 / ST3232E
- Exar SP3232 (SP3232E)
Note: verify same supply voltage (e.g., 3.3V) and pinout. L/TR denotes lead-free, tape-and-reel packaging.

Features

SP3223EEY-L/TR is a 2-channel RS-232 transceiver with these typical features:
- 2 transmitters and 2 receivers (2/2 channel)
- Single-supply operation from 3.3V to 5.5V
- Internal charge-pump to generate RS-232 level swings (typical ±6V)
- Data rate up to about 1 Mbps per channel (RS-232 rate capability)
- TTL/CMOS logic inputs compatible with 3.3V logic
- Meets EIA/TIA-232 standard for RS-232 signaling
- Low power consumption with possible power-down/shutdown option
- 8-pin package; L indicates lead-free and TR indicates Tape & Reel packaging
Note: exact temp range (often -40°C to 85°C for industrial) and current specs can vary by revision; consult the datasheet for precise limits.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC)
- Function: Dual RS-232 transceiver (two drivers and two receivers) for converting TTL/CMOS logic levels to RS-232 levels for serial communication. Package marked for reel/tray (L/TR).

Manufacturer

- Manufacturer: Sipex Corporation (now part of Exar; overall product lines are now under MaxLinear).
- What kind of company: A semiconductor company that designs and manufactures analog and mixed-signal integrated circuits (e.g., RS-232 transceivers).

Application

SP3223EEY-L/TR is a two-driver/two-receiver RS-232 transceiver. Common application areas:
- RS-232 serial interfaces for microcontrollers/embedded systems
- Serial console/communications ports in PCs, modems, routers, and networking gear
- Industrial automation and control panels
- Data acquisition, test & measurement instruments, data loggers
- Telemetry and remote sensing systems
- Point-of-sale terminals, printers, kiosks
- Medical instrumentation requiring RS-232 links
These are typical use cases where robust RS-232 signaling over short-to-moderate distances is needed.

Package

SP3223EEY-L/TR uses an 8-pin Small-Outline Package (SOP-8/SOIC-8). The “-L” indicates Pb-free (lead-free) finish and “-TR” means Tape & Reel packaging.
