The SP337EBEY-L/TR is a high-performance RS-232 transceiver IC manufactured by EXAR Corporation. Below are its key specifications, descriptions, and features:

Manufacturer: EXAR

Part Number: SP337EBEY-L/TR

Description:

The SP337EBEY-L/TR is a 3.3V-powered RS-232 transceiver designed for robust serial communication in industrial, embedded, and computing applications. It integrates charge-pump circuitry to generate RS-232 voltage levels from a single 3.3V supply.

Key Features:

• Single 3.3V Power Supply – Eliminates the need for dual ±12V supplies.
• Compliant with EIA/TIA-232-F Standards – Ensures compatibility with legacy RS-232 devices.
• Data Rates up to 1Mbps – Supports high-speed serial communication.
• Integrated Charge Pump – Generates ±5.5V RS-232 output levels.
• Low Power Consumption – Optimized for power-sensitive applications.
• ESD Protection – ±15kV (Human Body Model) on transceiver pins for enhanced reliability.
• Auto-Powerdown Feature – Reduces power consumption when inactive.
• Small Package Option – Available in a TSSOP-28 package for space-constrained designs.

Applications:

• Industrial control systems
• Point-of-sale (POS) terminals
• Networking equipment
• Embedded systems
• Medical devices

Package Type: TSSOP-28

Operating Temperature Range: -40°C to +85°C
