HD26C32A
2. Unidirectional Transmission (1 : n Configuration)
With this connection method, n receivers are connected for one driver. In the RS-422A standard, ten receivers can be
connected simultaneously for one driver.
Conversely, it is also possible to connect one receiver for n drivers.
3. Bidirectional Transmission
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.
