亚信电子提醒您  
亲爱的客户您好:

假如在使用亚信USB 转以太网路产品有不正常的现象,请下载 " How to identify authentic ASIX USB to LAN Products " 文件,先自行确认一下是否正在使用非真正亚信USB转以太网路芯片的产品。如果您买到非真正亚信USB转以太网路芯片的产品,请找该产品制造商或经销商要求相关驱动程序与技术支持。

 ZT491E -- 低功耗5V 10Mbps RS485收发器 (14引脚, 全双工)

The ZT485E series devices are 5V differential data line transceivers for RS485/RS422 communication that consist of one driver and one receiver with high level of ESD protection. They are designed for balanced transmission lines interface that meet ANSI standard TIA/EIA-485-A and ISO 8482:1987(E) specifications.

The ZT485E series devices span out with half or full duplex, data rate guaranteed at 250K bit per second or 10Mbps, and allow one unit load that fan out 32 devices sharing a common bus. The I/Os are enhanced-electrostatic discharge (ESD) protected, exceeding ±15kV Human Body Model (HBM).

规格:

  • Meets or exceeds the requirements of ANSI Standard TIA/EIA-485-A and ISO 8482:1987(E) specifications for Vcc at +5V ±10%
  • Low quiescent current - 0.5mA typ., 1mA max
  • Low shutdown current (where applicable) - 1μA typical, 10μA max
  • Guaranteed standard data rate 250Kbps or 10Mbps
  • True Fail-Safe (Open and Short) Receiver
  • -7V to +12V common-mode input voltage range
  • Half-Duplex or Full-Duplex configuration
  • Allows up to 1 unit load (32 devices) on the same common bus
  • Controlled driver output slew rate and receiver input filtering
  • Active-high driver enable and active-low receiver enable
  • ESD Protection on bus terminals
    • ±15kV Human Body Model (HBM)
  • Drop-in Replacements for MAX483E, MAX485E, MAX488E, MAX489E, MAX490E, MAX491E
  • High fanout driving 1/8 unit load (256 devices) available on the ZT485H Series

目标应用:
  • RS-422/RS-485 communications
  • Utility meters
  • Industrial process control
  • Building automation
  • Level translators
  • Transceivers for EMI-sensitive applications
  • Routers and HUBs
  • Industrial-controlled Local Area Networks
  • Industrial PCs, embedded PCs and peripherals
