The device contains four independent differential receivers, each converting a differential input signal to a single-ended CMOS\/TTL output. The +\/-200mV input sensitivity complies with RS-422 specifications, and the wide common-mode range (-0.2V to VCC-0.2V) provides noise immunity in noisy industrial environments. The fail-safe feature ensures that open-circuited or short-circuited inputs produce a logic HIGH output, preventing undefined states on the bus. The 32 MHz data rate supports high-speed communication links. The device is pin-compatible with the industry-standard DS26LS32 and AM26LS32 but with lower voltage operation capability.","working_principle":"The DS26LV32ATMX contains four independent differential receivers, each consisting of a precision differential comparator followed by a level-shifting output stage. Each receiver compares the voltage difference between its A and B inputs: when (A - B) exceeds +200mV, the output Y goes HIGH; when (A - B) is less than -200mV, the output Y goes LOW. The wide common-mode range allows the inputs to be offset from ground by common-mode noise without affecting the differential sensing. The fail-safe circuit monitors the input common-mode voltage: when both inputs are floating (open circuit) or shorted together, the common-mode voltage drops below the threshold, and the output is forced HIGH. This prevents the output from oscillating or assuming an undefined state when the bus is idle. The 22ns propagation delay includes the comparator response time and output drive delay. The output stage drives CMOS and TTL logic levels with appropriate output current for driving multiple logic inputs.","pin_description":"
