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.

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.

ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
