DescriptionThe SN65HVD20P is designed as one kind of extended common-mode RS-85 transceiver, SN65HVD20P can be used in (1)factory automation; (2)security networks; (3)building HVAC; (4)electrical power inverters; (5)industrial drives; (6)avionics. And this device combines a 3-state differential driver and a differential receiver, which operate from a single 5-V power supply.
Features of the SN65HVD20P are:(1)common-mode voltage range (-20 V to 25 V) more than doubles TIA/EIA-485 requirement; (2)receiver equalization extends cable length, signaling rate (HVD23, HVD24); (3)reduced unit-load for up to 256 nodes; (4)bus I/O protection to over 16-kV HBM; (5)failsafe receiver for open-circuit, short-circuit and idle-bus conditions; (6)low standby supply current 1-A max; (7)more than 100 mV receiver hysteresis.
The absolute maximum ratings of the SN65HVD20P can be summarized as:(1)Supply voltage: -0.5 V to 7 V;(2)Voltage at any bus I/O terminal: -27 V to 27 V;(3)Voltage input, transient pulse, A and B through 100 : -60 V to 60 V;(4)Voltage input at any D, DE or RE terminal: -0.5 V to VCC+ 0.5 V;(5)Receiver output current, IO: -10 mA to 10 mA;(6)Continuous total power dissipation: See Power Dissipation Rating Table;(7)Junction temperature: 150°C.
The electrical characteristics of the SN65HVD20P can be summarized as:(1)Input clamp voltage: -1.5 to 0.75 V;(2)Open-circuit output voltage: 0 to VCC V;(3)Change in steady-state differential output voltage between logic states: -0.1 to 0.1 V;(4)Steady-state common-mode output voltage: 2.1 to 2.9 V;(5)Differential output voltage over and under shoot: 10 %;(6)Input current: -100 to 100 A;(7)Short-circuit output current: -250 to 250 mA.
