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.

NOTES: 1. All voltage values are with respect to the network GND (unless otherwise specified).
2. All four channels of this device may conduct rated current simultaneously; however, power dissipation average over a short time
interval must fall within the continuous dissipation range.
3. For operation above 25°C free-air temperature, derate linearly at the rate of 16.6 mW/°C. For operation above 65°C case temperature,
derate linearly at the rate of 59 mW/°C. To avoid exceeding the design maximum virtual junction temperature, these ratings should
not be exceeded.
