description

The SN75439 quadruple peripheral driver is designed for use in systems requiring high current, high voltage, and high load power. The device features two inverting and two noninverting open-collector outputs with a common-enable input that, when taken high, disables all four outputs. By pairing each inverting channel with a corresponding noninverting channel (such as channel 1 paired with channel 2 and channel 3 paired with channel 4), the device may be used as a complete full-step 4-phase dc stepper-motor driver using only two input logic control signals plus the enable signal, as shown in Figure 3. Other applications include driving relays, lamps, solenoids, motors, LEDs, transmission lines, hammers, and other high-power-demand loads.

The SN75439 is characterized for operation from 0°C to 70°C.
