CMOS Output Driver
The LTC1480 transceiver provides full RS485 compatibility
while operating from a single 3.3V supply. The RS485
specification requires that a transceiver withstand common
mode voltages of up to 12V or –7V at the RS485 line
connections. Additionally, the transceiver must be immune
to both ESD and latch-up. This rules out traditional CMOS
drivers, which include parasitic diodes from their driver
outputs to each supply rail (Figure 9). The LTC1480 uses a
proprietary process enhancement which adds a pair of
Schottky diodes to the output stage (Figure 10), preventing
