英语翻译The MAX3222/MAX3237/MAX3241’s output stage isturned off

英语翻译
The MAX3222/MAX3237/MAX3241’s output stage is
turned off (high impedance) when the device is in shutdown
mode.When the power is off,the MAX3222/
MAX3232/MAX3237/MAX3241 permit the outputs to be
driven up to ±12V.
The transmitter inputs do not have pull-up resistors.
Connect unused inputs to GND or VCC.
MAX3237 MegaBaud Operation
In normal operating mode (MBAUD = GND),the
MAX3237 transmitters guarantee a 250kbps data rate
with worst-case loads of 3k½ in parallel with 1000pF.
This provides compatibility with PC-to-PC communication
software,such as Laplink™.
For higher speed serial communications,the MAX3237
features MegaBaud operation.In MegaBaud operating
mode (MBAUD = VCC),the MAX3237 transmitters guarantee
a 1Mbps data rate with worst-case loads of 3k½ in
parallel with 250pF for 3.0V < VCC < 4.5V.For 5V ±10%
operation,the MAX3237 transmitters guarantee a 1Mbps
data rate into worst-case loads of 3k½ in parallel with
1000pF.
RS-232 Receivers
The receivers convert RS-232 signals to CMOS-logic output
levels.The MAX3222/MAX3237/MAX3241 receivers
have inverting three-state outputs.In shutdown,the
receivers can be active or inactive (Table 1).
The complementary outputs on the MAX3237 (R1OUTB)
and the MAX3241 (R1OUTB,R2OUTB) are always active,
regardless of the state of EN or SHDN.This allows for
Ring Indicator applications without forward biasing other
devices connected to the receiver outputs.This is ideal
for systems where VCC is set to 0V in shutdown to
accommodate peripherals,such as UARTs (Figure 2).
请高手翻译成中文

当驱动器处于关闭模式的时候,MAX3222/MAX3237/MAX3241的输出平台也会关掉(高电阻).当电源不再供电的时候(停电) MAX3222/MAX3232/MAX3237/MAX3241芯片允许输出电压上升到正负12伏特.发生器的输入段没有上拉电阻.把不使用的输入端连接到接地端或者电路供电电压端.
MAX3237兆波特工作时,在普通工作模式时(MBAUD＝接地端) MAX3237芯片传送速率在的有3000欧姆电阻,并行电容1000pF最不利的条件下达到250kbps,芯片还提供了PC机与PC机之前通讯兼容性软件(比如LapLink™).
为了高速连续通信MAX3237芯片的特征是兆比特传输模式.在兆比特传输模式, MAX3237芯片在最恶劣的3千欧姆电阻,250pF并行电容和VCC电压在3伏特到4.5伏特之间的时候,传输速率可以达到1Mbps.在供电电压在5伏特的正负百分之十之内,在最坏3000欧姆电阻和1000pF并行电容的条件下,传输速率也能达到1Mbps.
RS-232接收器
接收器把RS-232的信号转换成CMOS可以识别的逻辑电平输出,MAX3222/MAX3237/MAX3241接收器可以转换3种输出水准.在关门状态,接收器可以活动或者停止.MAX3237和MAX3241的补充输出端口,不管EN或者SHDH的状态.它允许铃声指示器在没有前置偏压去连接其他接收器输出的时候运行.这个是理想的系统：当处于关门状态的时候,VCC对外围设备的供应电压是0伏特,就像UARTs(通用非同步收发传输器)一样.
