The AM26C32MJR is a quadruple differential line receiver from Texas Instruments compliant with TIA\/EIA-422-B, TIA\/EIA-423-B, and ITU V.10\/V.11 standards. It features \u00b17V common-mode range with \u00b1200mV input sensitivity, 60mV input hysteresis, and fail-safe open-input detection (output goes high). BiCMOS technology reduces power to one-fifth of the AM26LS32. The MJR suffix denotes military-grade -55\u00b0C to +125\u00b0C operation in 16-pin CDIP.<\/p>\n

It features \u00b17V common-mode input range with \u00b1200mV sensitivity across the full range, 60mV input hysteresis for noise rejection, and a fail-safe circuit that forces the output high when inputs are open (detecting broken wires). BiCMOS fabrication reduces power consumption to approximately one-fifth of the bipolar AM26LS32 while maintaining AC and DC performance. The MJR suffix specifies the ceramic CDIP package with -55\u00b0C to +125\u00b0C operation and MIL-PRF-38535 qualification for military applications.","working_principle":"Each of the four AM26C32 receivers compares the voltage difference between its A and B inputs. When VA - VB exceeds +200mV, the output Y goes high; when VA - VB falls below -200mV, Y goes low. The 60mV hysteresis band prevents output oscillation when the differential input is near the switching threshold. The \u00b17V common-mode range means the inputs can be at any voltage from -7V to +7V relative to ground, as long as the differential voltage exceeds the \u00b1200mV threshold \u2014 critical in industrial environments where ground potential differences between transmitter and receiver can be significant. The fail-safe circuit biases the inputs so that if both A and B are floating (broken cable), the output defaults to a defined high state. The 3-state outputs are controlled by dual enable pins (G and G\u0304), allowing multiple receivers to share a common data bus in bus-organized systems.","pin_description":"

      • Military RS-422 Communication Link:<\/b> Pair with the AM26C31MJR driver to form a complete military-grade RS-422 data link. The \u00b17V common-mode range handles ground potential differences between vehicles or shelters. The fail-safe circuit detects cable disconnection, triggering an alarm in the system controller. The ceramic package and -55\u00b0C to +125\u00b0C rating ensure reliability in extreme environments.<\/li>
      • Industrial Encoder Receiver:<\/b> Receive quadrature encoder signals from a remote motor. The 60mV hysteresis rejects induced noise on long cable runs near motor drives. The \u00b1200mV sensitivity allows the encoder signals to attenuate over distance without loss of reception. The 10Mbps data rate supports high-resolution encoders at 3000+ RPM.<\/li>
      • Smart Grid Data Concentrator:<\/b> Use the four receivers to accept data from up to four RS-422 metering nodes. The 3-state outputs allow all four receiver outputs to connect to a shared MCU data bus, with the enable pins selecting which receiver's data is read. The fail-safe feature ensures that a disconnected meter is detected immediately.<\/li><\/ul>","alternative_models":"
