长线也就是差分驱动 优点是可以更高速 缺点是驱动电压是5V 假如你用PLC 的话选型要选带差分高速脉冲输出的才能用这模式 一般指采用差分方式的信号接号 采用26C31 TTL输入 差分输出 并采用26C32接收 差分输入 TTL输出 长线驱动由于采用差分方式 故抗干扰能力强 传输速度快 如多数增量量编码器的信号输出都采用此接口">长线也就是差分驱动 优点是可以更高速 缺点是驱动电压是5V 假如你用PLC 的话选型要选带差分高速脉冲输出的才能用这模式 一般指采用差分方式的信号接号 采用26C31 TTL输入 差分输出 并采用26C32接收 差分输入 TTL输出 长线 [更多]

• Meets or Exceeds the Requirements of ANSI
TIA/EIA-422-B, TIA/EIA-423-B, and ITU
Recommendation V.10 and V.11
(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.
The AM26C32 is a quadruple differential line receiver for balanced or unbalanced digital data transmission. The
enable function is common to all four receivers and offers a choice of active-high or active-low input. The 3-state
outputs permit connection directly to a bus-organized system. Fail-safe design specifies that if the inputs are
open, the outputs always are high.
The AM26C32 devices are manufactured using a BiCMOS process, which is a combination of bipolar and CMOS
transistors. This process provides the high voltage and current of bipolar with the low power of CMOS to reduce
the power consumption to about one-fifth that of the standard AM26LS32, while maintaining ac and dc
performance.
The AM26C32 is characterized for operation over the extended temperature range of – 55 ° C to 125 ° C.
