The MAX13450E/MAX13451E are half-duplex and full-duplex RS-485/RS-422 transceivers. These devices feature internal 100Ω and 120Ω termination resistors. The resistor values are pin selectable. A logic supply input allows interfacing to logic levels down to +1.8V.
The MAX13450E/MAX13451E feature strong drivers specified to drive low-impedance lines found when a fully loaded bus, based on today's 100Ω characteristic impedance cable, is doubly terminated. Both devices allow slew-rate limiting of the driver output to reduce EMI and reflections for data rates up to 500kbps.
The MAX13451E has a FAULT alarm indication output to signal to the system that an error condition exists in the driver. The MAX13451E also features a logic inversion function. The logic inversion allows phase reversal of the A-B signals in case these are inadvertently connected wrongly.
The MAX13450E/MAX13451E have 1/8-unit load receiver input impedance, allowing up to 256 transceivers on the bus. All driver outputs are protected to Q30kV ESD using the Human Body Model (HBM).
The MAX13450E/MAX13451E are available in a 14-pin TSSOP package and operate over the automotive -40℃ to +125℃ temperature range.
   基于MAX13450E/MAX13451E单片机的以上特点,龙芯世纪芯片解密中心能在短时间内为您完成MAX13450E片解密MAX13451E片解密等疑难单片机解密服务。如果您有MAX14811单片机解密需求,欢迎来电来访咨询洽谈。
