DESCRIPTION
Receiver Output. If the receiver output is enabled (RE low) and A–B > 200mV, then RO will be high.
If A–B < –200mV, then RO will be low. If the receiver inputs are open, shorted, or terminated without a
signal, RO will be high. Integrated 250kΩ pull-up to VCC.
Receiver Enable. A low input enables the receiver. A high input forces the receiver output into a high
impedance state. If RE is high with DE low, the part will enter a low power shutdown state.
Driver Enable. A high input on DE enables the driver. A low input will force the driver outputs into a high
impedance state. If DE is low with RE high, the part will enter a low power shutdown state.
Driver Input. If the driver outputs are enabled (DE high), then a low on DI forces the driver noninverting
output A low and inverting output B high. A high on DI, with the driver outputs enabled, forces the
driver noninverting output A high and inverting output B low.
Ground.
Connect the exposed pad on the DFN packages to GND.
Inverting Receiver Input and Inverting Driver Output.
Impedance is ~112kΩ in receive mode or unpowered.
Noninverting Receiver Input and Noninverting Driver Output.
Impedance is ~112kΩ in receive mode or unpowered.
Power Supply. 3V < VCC < 5.5V. Bypass with 1µF ceramic capacitor to GND for best ESD performance.
