BUS DRIVER / RECEIVER  
The ULQ2470L and ULQ2470M are bi-directional bus driver /  
receivers designed specifically for automotive applications. They are  
intended to be used as an interface between a microprocessor and a  
single-wire multiplex data bus operating from the A-line or battery.  
Each device consists of a wave-shaped open-collector driver, a pull-up  
resistor, and an input filter and buffer.

Output driver protection circuitry provides output shutdown if  
currents in excess of 25 to 30 mA occur. Additionally, over-voltage  
shutdown occurs when the bus voltage exceeds approximately  
22 volts.
