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。

  我了解

 ZT487E -- 低功耗5V 250Kbps 128-Fanout RS485收发器

The ZT487E 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 ZT487E devices spans out with half duplex, data rate guaranteed at 250K bit per second, and allow one-fourth of an unit load that fan out 128 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 ±5%
  • Low quiescent current - 0.5mA typ., 1mA max
  • Low shutdown current (where applicable) - 0.01μA typical, 10μA max
  • Guaranteed standard data rate 250Kbps
  • Thermal shutdown protection
  • -7V to +12V common-mode input voltage range
  • Half-Duplex configuration
  • Allows up to 1/4 unit load (128 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 MAX487E, SN75LBC182
  • Standard fanout driving 1 unit load (32 devices) available on the ZT487E

目标应用:
  • RS422/RS485 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
  • Industrial, security CATV and camera application
