亞信電子提醒您  
親愛的客戶您好:

假如在使用亞信USB轉乙太網路產品有不正常現象,請下載 " How to identify authentic ASIX USB to LAN Products " 文件,先自行確認一下是否正在使用非真正亞信USB轉乙太網路晶片的產品. 如果您買到非真正亞信USB轉乙太網路晶片的產品,請找該產品製造商或經銷商要求相關驅動程式與技術支持.

  我瞭解

 ZT3070E -- 低功耗3V 250Kbps RS485收發器 (具備14接腳, 全雙工)

The ZT3070E series devices are 3V 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 ZT3070E series devices span out with half or full duplex, data rate guaranteed at 250Kbps, 500Kbps or 16Mbps, and allow 1/8 unit load that fan out 256 devices sharing a common bus. The I/Os are enhanced-electrostatic discharge (ESD) protected, exceeding ±15Kv Human Body Model (HBM).

規格:

  • Meets or exceeds the requirements of ANSI Standard TIA/EIA-485-A and ISO 8482:1987(E) specifications for Vcc at +3.3V ±10%
  • Low quiescent current – 0.5mA typ., 1.5mA max
  • Low shutdown current (where applicable) - 0.05μA typical, 10μA max
  • Guaranteed standard data rate 250Kbps, 500Kbps, or 16Mbps
  • True Fail-Safe (Open and Short) Receiver
  • -7V to +12V common-mode input voltage range
  • Half-Duplex or Full-Duplex configuration
  • Allows up to 1/8 unit load (256 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 MAX3070E, MAX3071E, MAX3072E, MAX3073E, MAX3075E, MAX3076E, MAX3077E, MAX3078E

應用目標:
  • 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
  • Industrial, security CATV and camera applications
