... Quadruple Differential Line Drivers With 3 State Outputs Description The HD26C32A provides differential line receivers which realize low power dissipation by CMOS process. The device has four receivers which meet the requirements of EIA standard RS-422A and RS-423A pin package. The enable function is common to all four receivers and offers a choise of active high or active low inputs. Fail safe design ensures that if the inputs are open the outputs will always be high ...

... Output Enable Receiver When bidirectional data exchange is performed using a combination of the HD26C31 and HD26C32A, since either high or low output control is possible, using complementary enable inputs for the driver and receiver makes it easy to configure the kind of combination illustrated in figure 8. Extending this combination makes it possible to exchange n-bit data simultaneously, and handle a party line system. ...
