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.

 ZT3243F -- Low Power +3V to +5.5V, 3D/5R 1000Kbps RS232 Transceivers (Features 28/32-pin)

The ZT3243F Series devices are 3V powered EIA/TIA-232 and V.28/V.24 communication interfaces with low power requirements. They consist of three line drivers, five line receivers and the proprietary switch-capacitor regulated voltage converters. 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 IEC61000-4-2 Air Gap Discharge and ±8kV IEC61000-4-2 Contact Discharge.

The ZT3243F Series feature 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.

Feature:

  • Meets or Exceeds the EIA/TIA-232F and CCITT V.28/V.24 Specifications for Vcc at +3.3V ±10% and +5V ±10% Operations
  • Interoperable with EIA/TIA-232 and adheres to EIA/TIA-562 down to a +2.7V power source
  • Low quiescent current – 0.5mA typ., 1mA max
  • Low shutdown current (where applicable) - 1µA typical, 10µA max
  • Guaranteed data rate 1000Kbps
  • Proprietary Switch-Capacitor Regulated Voltage Converters (patent pending)
  • Proprietary AUTOGREEN Power Saving (patent pending)
  • Latch-up Free
  • ESD Protection for RS-232 I/O’s
    • ±15kV Human Body Model (HBM)
    • ±15kV IEC61000-4-2 Air Gap Discharge
    • ±8kV IEC61000-4-2 Contact Discharge
  • Pin and Function Compatible Replacements for MAX3245E, ICL3245, ISL4245E, and SP3243U
  • Standard Data Rate at 250Kbps Available on ZT3243E Series
Target Applications:
  • Battery-Powered And Hand-Held Applications
  • Notebooks, Subnotebooks, and Palmtops
  • Industrial and Embedded PCs
  • Data Cables for Cell Phones and PDAs
  • Terminal Adapters and POS terminals
  • Peripherals interface
  • Routers and HUBs
