2470BUS DRIVER / RECEIVER
BUS DRIVER / RECEIVER
The ULQ2470L and ULQ2470M are bi-directional bus driver /
ULQ2470M
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.
