Live Insertion or Removal of Package  
Driver Maintains High Impedance with the  
Power Off  
Excessive power dissipation caused by bus contention or  
faults is prevented by a thermal shutdown circuit which  
forces the driver outputs into a high impedance state. The  
receiver has a fail safe feature which guarantees a high  
output state when the inputs are left open.  
Combined Impedance of a Driver Output and  
Receiver Allows up to 32 Transceivers on the Bus  
70mV Typical Input Hysteresis  
28ns Typical Driver Propagation Delays with  
5ns Skew  
Pin Compatible with the SN75179  
Both AC and DC specifications are guaranteed from 0°C to  
70°C and 4.75V to 5.25V supply voltage range.
