SP332 transceiver equivalent, rs-232/rs-485 multi-mode serial transceiver.
500mV of hysteresis margin to minimize the affects of noisy tranmission lines. The inputs also have a 5kΩ resistor to ground, in an open circuit situation the input of th.
The SP332 is a monolithic device that contains both RS-232 and RS-485 line drivers and receivers. The configuration of the SP332 can be changed at any time by changing the logic state of two control input pins. The device also includes a loop back f.
