Overview
2470 BUS DRIVER / RECEIVER 2470 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.
