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.

 ZT3232F -- Low Power +3V to +5.5V, 1000Kbps RS232 Transceivers (Features 16-pin, 2D/2R)

The ZT32xxF series devices are 3V powered EIA/TIA-232 and V.28/V.24 communication interfaces with low power requirements. They consist of two line drivers, two line receivers and the proprietary switch-capacitor regulated voltage converters. The ZT3220F has a 1Tx and 1Rx configuration. These devices operate from a single 3V to 5.5V power supply at the guaranteed data rate of 1000K bits/sec with enhanced electrostatic discharge (ESD) protection in all RS232 I/O pins exceeding ±15kV EN61000-4-2 Air Gap Discharge and ±8kV EN61000-4-2 Contact Discharge.

The ZT3221F and ZT3223F features the AUTOGREEN (patent pending) proprietary function which automatically powers down the on-chip regulated voltage converters and driver circuits when an RS-232 cable is disconnected from the host interface or when a connected peripheral device is turned off.


  • Meets EIA/TIA-232F and CCITT V.28/V.24 specifications for Vcc at +3.3V ±10% and +5V ±10%
  • Low Quiescent Current: 0.5mA typ., 1mA max
  • Low Shutdown Current (where applicable): 1µA typical, 10µA max
  • Guaranteed High Data Rate 1000Kbps
  • Proprietary Switch-Capacitor Regulated Voltage Converters (patent pending)
  • Proprietary AUTOGREEN Power Saving (patent pending)
  • Latch-up Free
