MAX1380E
___________________________________ 概述
___________________________________ 特性
–
MAX13080E MAX13089E是+5.0V供电、具有 15kV ESD
♦ +5.0V工作电压
保护的RS-485/RS-422收发器，包含一路驱动器和一路接
收器。这些器件具有失效保护电路，当接收器输入开路
或短路时，确保接收器输出逻辑高电平。如果挂接在终
端匹配总线上的所有发送器都禁用(高阻)，接收器将输出
♦ 为RS-485/RS-422 I/O引脚提供增强型ESD保护
15kV人体模式
♦ 真正的失效保护接收器兼容于EIA/TIA-485
♦ DE与RE采用热插拔输入结构
–
逻辑高电平。MAX13080E MAX13089E具有热插拔功能，
在上电或热插入时可以消除总线上的故障瞬变信号。
♦ 强大的摆率控制功能有助于实现无差错数据传输
(MAX13080E–MAX13085E/MAX13089E)
MAX13080E/MAX13081E/MAX13082E具有低摆率驱动器，
能够减小EMI和由于不恰当的电缆端接所引起的反射，实现
高达250kbps的无差错数据传输；MAX13083E/MAX13084E/
MAX13085E具有限摆率驱动器，可实现高达500kbps的传
输速率；MAX13086E/MAX13087E/MAX13088E驱动器的摆
率不受限制，可实现高达16Mbps的传输速率；MAX13089E的
摆率可以由引脚选择，以适应250kbps、500kbps和16Mbps的
传输速率。
MAX13089E
♦ 低电流关断模式
(MAX13081E/MAX13084E/MAX13087E除外)
♦ 可通过引脚选择全双工/半双工模式(MAX13089E)
♦ 为纠正双绞线反接提供相位控制(MAX13089E)
♦ 总线上允许挂接多达256个收发器
♦ 提供工业标准的8引脚SO封装
MAX13082E/MAX13085E/MAX13088E用于半双工通信；
MAX13080E/MAX13081E/MAX13083E/MAX13084E/
MAX13086E/MAX13087E用于全双工通信；MAX13089E
可以设置为半双工或全双工通信，并具有独立的、可由
引脚设置的接收器与发送器输出相位。

__________________________________详细说明
(A - B)小于或等于-200mV，RO为逻辑低电平。当挂接在
终端匹配总线上的所有发送器都禁用时，接收器差分输
入电压将通过终端电阻拉至0V。依据MAX13080E系列的
接收器门限，可实现具有50mV最小噪声容限的逻辑高电
平。与以往的失效保护器件不同，-50mV至-200mV门限电
压符合 200mV的EIA/TIA-485标准。
MAX13080E–MAX13089E系列高速RS-485/RS-422收发器
包括一路驱动器和一路接收器。这些器件具有失效保护
电路，当接收器输入短路或开路时，或当终端匹配传输
线上的所有驱动器均处于禁用状态时，可确保接收器
输出逻辑高电平(参考失效保护部分)。MAX13080E/

MAX13088E/MAX13089E还具有热插拔功能，支持热插入
而不会产生数据传输错误(参考热插拔功能(MAX13081E/
MAX13084E/MAX13087E 除外)部分)。MAX13080E/
MAX13081E/MAX13082E的低摆率驱动器可降低EMI，并
减小由不恰当的端接电缆引起的反射，能够实现最大
250kbps的无差错数据传输；MAX13083E/MAX13084E/
MAX13085E也具有摆率限制功能，能够实现最大500kbps
的传输速率；MAX13086E/MAX13087E/MAX13088E的驱
动器摆率不受限制，能够实现最大16Mbps的传输速率；
MAX13089E的摆率可通过三态驱动器的选择引脚进行选

MAX13089E
(MAX13081E/MAX13084E/MAX13087E除外)
热插拔输入
把电路板插入带电或正在工作的背板时，数据总线的差
分干扰可能导致数据错误。电路板插入背板时，数据通
信处理器启动一次上电过程。在此过程中，处理器的逻
辑输出驱动器为高阻态，不能将这些器件的DE和RE输入
驱动至规定的逻辑电平。处理器的逻辑驱动器在高阻态
时可能会有高达 10µA的漏电流，这会引起收发器的标
准CMOS使能输入漂移到不正确的逻辑电平。此外，电路
板寄生电容还会将VCC或者GND耦合至使能输入端。如
果不具备热插拔能力，以上因素会错误地使能收发器的
驱动器或接收器。
MAX13082E/MAX13085E/MAX13088E为半双工收发器；
MAX13080E/MAX13081E/MAX13083E/MAX13084E/
MAX13086E/MAX13087E为全双工收发器；MAX13089E可
通过将选择引脚(H/F)接高电平或低电平分别选择半双工
或全双工通信模式。
V
CC上升时，内部下拉电路保持DE为低电平，RE 为高电
平。完成初始上电过程后，下拉电路不起作用，并复位
热插拔输入端。
所有器件均采用+5.0V单电源供电。驱动器具有输出短路
限流功能。热关断电路保护驱动器不会出现功耗过大。
进入热关断保护后，驱动器输出被置于高阻态。
热插拔输入电路
使能输入端具备热插拔能力。输入端有两个NMOS器件：
M1和M2 (图9)。当VCC由零开始上升时，内部7µs定时器
打开M2，设置SR锁存器，而锁存器又同时打开M1。晶
体管M2可吸收1.5mA电流，M1可吸收500µA电流，通过
一个5kΩ电阻将DE下拉至GND。为防止高达100pF的外部
寄生电容将DE驱动至高电平，M2设计用于将DE拉至禁
用状态。7µs之后，定时器关闭M2，M1继续导通，以保
持DE为低电平，并防止三态漏电流将DE驱动至高电平。
直到外部驱动源提供所需的输入电流后，才关闭M1。此
时，SR锁存器复位，M1关闭。M1关闭时，DE恢复为标
准高阻CMOS输入。只要VCC降至1V以下，就会复位热插
拔输入电路。
接收器输入滤波
–
MAX13080E MAX13085E以及工作在250kbps或500kbps模
式下的MAX13089E，其接收器除了具有输入滞回外，还
包括输入滤波功能。此滤波功能提高了上升和下降缓慢
的差分信号的噪声抑制能力。滤波器使接收器传输延时
增加25%。
失效保护
接收器输入短路或开路时，或挂接在终端匹配传输线上
的所有驱动器均处于禁用状态时，MAX13080E系列可确
保接收器输出逻辑高电平。这是通过将接收器输入门限
分别设置为-50mV和-200mV实现的。若差分接收器输入电
对于RE，互补电路采用两个PMOS器件将RE上拉至VCC
。

通过分压电阻连接到驱动器的输出端，从而改变了驱动

类似于Maxim的其它相关器件，所有引脚都采用了ESD保
护结构，在操作与装配过程中出现静电放电时可对器件
提供保护。MAX13080E系列产品的驱动器输出与接收器
输入具有额外的静电保护能力。Maxim的工程师们已开发
出目前技术水平最高的电路结构，为这些引脚提供保护，
使其能够承受 15kV的ESD冲击。ESD保护结构在所有状

MAX13089E编程
MAX13089E提供几种可编程工作模式。可编程发送器的
上升和下降时间，实现最大250kbps、500kbps和16Mbps的
数据速率。为选择所需的数据速率，可通过三态驱动器
驱动SRL至三种可能的状态之一：VCC、GND或悬空。对
于250kbps传输速率，设置三态驱动器为高阻态或使SRL
悬空。对于500kbps传输速率，驱动SRL至高电平或连接
至VCC。对于16Mbps传输速率，驱动SRL至低电平或连接
至GND。SRL状态可在器件工作期间进行修改，而不必中
断数据通信。
ESD测试条件
ESD性能取决于多种条件。若需包括测试条件、方法和结
果在内的可靠性报告，请与Maxim联系。
人体模型
图10a所示为人体模型，对低阻放电时产生的电流波形如
图10b所示。该模型包括一个100pF电容，先充电至所需
的ESD电压，然后通过1.5kΩ电阻向被测器件放电。
IEC 61000-4-2
双绞线有时会出现接反的情况。MAX13089E的两个引脚
可以翻转驱动器和接收器的相位，从而纠正这种错误连
接。正常工作情况下，驱动TXP和RXP至低电平、将它们
连接至地或悬空(具有内部下拉)。驱动TXP至高电平或将
其连接至VCC来翻转驱动器相位；驱动RXP至高电平或将
其连接至VCC来翻转接收器相位。注意，当RXP为高电平
时接收器门限值为正。
IEC 61000-4-2标准涵盖了成品设备的ESD测试与性能，但
它并不是专门针对集成电路。MAX13080E系列器件帮助
用户设计符合IEC 61000-4-2要求的设备，而不需要额外的
ESD保护元件。
使用人体模型与IEC 61000-4-2进行测试的主要区别在于
IEC 61000-4-2测试的峰值电流更高，这是由于IEC 61000-
4-2模型具有更小的串联电阻。因此，IEC 61000-4-2测试
的ESD耐受电压通常低于使用人体模型测试的结果。图10c
所示为IEC 61000-4-2模型，图10d所示为IEC 61000-4-2 ESD
接触放电测试的电流波形。
MAX13089E可工作于全双工或半双工模式。驱动H/F至低
电平、保持该引脚悬空(具有内部下拉)，或者将其连接至
GND可实现全双工模式。驱动H/F至高电平实现半双工

可任意组合，或者与其它RS-485收发器进行组合，只要
总负载不超过32个单位负载，都可以挂接在同一总线上。
机器模型ESD测试采用200pF存储电容和零放电电阻对所
有引脚进行测试。其目的是模拟测试和装配过程中操作
设备接触I/O引脚所产生的静电冲击。当然所有引脚都需
要这种保护，而不只是RS-485输入与输出引脚。
降低EMI和反射
MAX13080E/MAX13081E/MAX13082E的低摆率驱动器可以
减小EMI，并降低由不恰当的终端匹配电缆引起的反射，
可实现最大250kbps的无差错数据传输。MAX13083E/
MAX13084E/MAX13085E提供较高的驱动器输出摆率，可
实现高达500kbps的传输速率。MAX13089E在SRL = VCC
或 者 S R L 悬 空 时 具 有 摆 率 控 制 功 能 。 S R L 悬 空 时 ，
MAX13089E可实现高达250kbps的无差错数据传输。SRL
连接至VCC时，数据传输速率可高达500kbps。
_______________________________ 应用信息

标准驱动器可最多驱动32个单位负载。MAX13080E系列
收发器的接收器具有1/8单位负载输入阻抗(96kΩ)，允许
最多256个收发器并行挂接在同一通信总线上。这些器件

低功耗关断模式
驱动器输出保护
(MAX13081E/MAX13084E/MAX13087E除外)
通过两种机制避免故障或总线冲突引起输出电流过大和
功耗过高。第一，输出级折返式限流，在整个共模电压
范围(参考典型工作特性)内提供快速短路保护。第二，热
关断电路，当管芯温度超过 +175°C (典型值)时，强制驱
动器输出进入高阻状态。
RE接高电平且DE接低电平时，启动低功耗关断模式。关
断模式下，器件仅吸收典型值为2.8µA的电源电流。
可以同时驱动RE和DE，如果RE为高电平且DE为低电平
的持续时间小于50ns，可以确保器件不会进入关断模式。
如果输入端维持这种状态700ns以上，则可确保这些器件
进入关断模式。
传输线长度
MAX13089E
RS-485/RS-422标准适用于最大4000英尺的线路长度。
对大于4000英尺的线路长度，可采用图11所示的线路中
继器。
使能时间 tZH与tZL (见Switching Characteristics 部分)假定
器件并未处于低功耗关断状态。使能时间 tZH(SHDN)
与
tZL(SHDN)假定器件处于关断状态。从低功耗关断模式到驱
动器和接收器转变为有效状态所需要的时间(tZH(SHDN)
tZL(SHDN))，要比从禁用模式下转变为有效状态所需要的
时间(tZH、tZL)长。

典型应用
MAX13082E/MAX13085E/MAX13088E/MAX13089E收发器
设计用于多点总线传输线上的双向数据通信。图12与图
13给出了典型网络应用电路。
为减小反射，应当在传输线两端以其特性阻抗进行终端
匹配，主干线以外的分支连线长度应尽可能短。具有摆
率限制的MAX13082E/MAX13085E以及工作在两种限摆率
模式下的MAX13089E能够允许不良终端匹配。
