ASIX Electronics Corporation Notice USB to LAN products 
Dear Customer:

If you got some problems on ASIX USB to LAN products, please download the How to identify authentic ASIX USB to LAN Products document to double check if your USB to LAN device includes an Non-authentic ASIX USB to LAN solution inside or not? If yes, please contact the manufacturer of your USB to LAN device to get proper drivers instead. ASIX DOES NOT GUARANTEE AND PROVIDE ANY SUPPORT FOR THOSE NON-AUTHENTIC ASIX PRODUCTS.

  Yes, I understand.

 ZT202E -- Low Power 5V 250Kbps RS232 Transceivers (Features 16-pin, ±9V Output Voltage Swing)

The ZT232E series devices are +5V powered EIA/TIA-232 and CCITT V.28/V.24 communication interfaces with low power requirements. These transceivers consist of two line drivers, two line receivers and the proprietary switch-capacitor regulated voltage converters. These devices operate from a single +5V power supply at the guaranteed data rate of 250K bits/sec with enhanced electrostatic discharge (ESD) protection in all RS232 I/O pins exceeding ±15kV HBM.


  • Meets EIA/TIA-232F and CCITT V.28/V.24 specifications for Vcc at +5V ±10%
  • Low Quiescent Current - 3mA typ., 5mA max
  • Low Shutdown Current (where applicable) - 1μA typical, 5μA max
  • Guaranteed Standard Data Rate 250Kbps
  • Proprietary Switch-Capacitor Regulated Voltage Converters (patent pending)
  • Use Small 0.1µF Capacitors
  • Wake Up Feature (where applicable) in Shutdown Mode
  • Tri-State Receiver Outputs
  • Latch-up Free
  • ESD Protection for RS-232 I/O’s
    • ±15kV Human Body Model (HBM)
  • Drop-in Replacements for MAX202E, MAX232E, SP202E, SP232E, SP310E, SP312E, ST202E, ST232E, HIN202E, HIN232E, ADM202E, ADM232L
  • High Data Rate at 1000Kbps Available on ZT232F Series
Target Applications:
  • Single Power Supply Applications
  • Industrial and Embedded PCs
  • Set Top Boxes
