description  
The SN75LBC775 is a low-power LinBiCMOS  
device that incorporates the drivers and receivers  
for an AppleTalk or a LocalTalk interface and a  
switched-capacitor voltage converter for a single  
5-V supply operation. LocalTalk uses a hybrid of  
RS-422 with the transceiver connected to the  
network through a small isolation transformer.  
The AppleTalk mode provides point-to-point  
communications and uses the same differential  
driver and receiver as LocalTalk with the addition  
of a hybrid RS-423, single-ended handshake  
driver (HSK) and receiver. In the AppleTalk mode,  
the port connects directly to the receiver with no  
isolation transformer.

While the device power is turned off (V  
= 0) or

disabled in the LocalTalk mode, the outputs are in  
a high-impedance state. When the driver enable  
(DEN) terminal is high, both the differential and  
serial driver outputs are in a high-impedance  
state.
