FEATURES… The SP504 is a highly integrated serial trans- ceiver that allows software control of its inter- face modes. Similar to the SP503, the SP504 offers the same hardware interface modes for RS-232 (V.28), RS-422A (V.11), RS-449, RS- 485, V.35, ...

Receivers The SP504 has seven (7) independent receivers which can be programmed for the different interface modes. Control for the mode selection is done via a 4–bit control word that is indepen- dent from the driver control word. The coding ...

The drivers are controlled with the data bits labeled TDEC TDEC . All of the drivers can be put into tri- 0 state mode by writing 0000 to the driver decode switch. The three drivers TxD, ...
