Rev.2.00, Jul.16.2004, page 6 of 12 HD26C32A HD26C32A Line Receiver Applications The HD26C32A is a line receiver that meets the EIA RS-422A and RS-423A conditions. It has a high in-phase input voltage range, both positive and negative, enabling highly reliable transmission to be performed even in noisy environments. Its main features are listed below. * * * * * Operates on a single 5 V power supply. 0.2 V input sensitivity in in-phase input voltage 7 V range Three-state output On-chip input fail-safe circuit On-chip power up/down protection circuit As shown by the logic diagram, the enable function is common to all four drivers, and either active-high or active-low input can be selected. When exchange is carried out using a party line system, it is better to keep the receiver input bias current constituting the driver load small, as this allows more receivers to be connected.

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 Driver Data Input/ Output RT RT Receiver Data Input/ Output Enable Enable Receiver Driver Figure 8 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.
