The SP233AET-L/TR is a dual RS-232 driver/receiver IC manufactured by EXAR Corporation. Below are its specifications, descriptions, and features:

Specifications:

  • Manufacturer: EXAR
  • Part Number: SP233AET-L/TR
  • Type: RS-232 Transceiver
  • Number of Drivers/Receivers: 2 Drivers, 2 Receivers
  • Data Rate: Up to 120 kbps
  • Supply Voltage (VCC): +5V
  • Operating Temperature Range: -40°C to +85°C
  • Package: 16-pin TSSOP (Thin Shrink Small Outline Package)
  • RoHS Compliant: Yes

Descriptions:

The SP233AET-L/TR is a low-power, dual RS-232 transceiver designed for serial communication applications. It integrates two drivers and two receivers, compliant with EIA/TIA-232-F standards. The device operates from a single +5V power supply and includes an onboard charge pump for generating the necessary RS-232 voltage levels (±5V to ±10V).

Features:

  • Low Power Consumption: Optimized for battery-powered applications.
  • Onboard Charge Pump: Eliminates the need for external voltage converters.
  • ESD Protection: ±15kV Human Body Model (HBM) on transmitter outputs and receiver inputs.
  • Wide Operating Temperature Range: Suitable for industrial environments.
  • Small Footprint: 16-pin TSSOP package for space-constrained designs.
  • Compatible with 3V and 5V Logic: Supports mixed-voltage systems.

This IC is commonly used in industrial control, embedded systems, and communication interfaces requiring reliable RS-232 connectivity.
