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.

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. 3–2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 SN75439 QUADRUPLE PERIPHERAL DRIVER SLRS013A – D3116, MAY 1988 – REVISED NOVEMBER 1989 recommended operating conditions Supply voltage, VCC MIN NOM MAX UNIT 4.75 5 5.25 V Output supply voltage in inductive switching circuit, VS (see Figure 2) High-level input voltage, VIH 2 – 0.3† Low-level input voltage, VIL Low-level output current, IOL 40 V 5.25 V 0.8 V 1.3 A Operating free-air temperature, TA 0 25 70 °C † The algebraic convention, in which the least positive (most negative) value is designated minimum, is used in this data sheet for logic voltage levels. electrical characteristics over recommended ranges of operating free-air temperature and supply voltages (unless otherwise noted) PARAMETER VIK VOL TEST CONDITIONS Input clamp voltage II = – 12 mA IOL = 0.5 A Low-level p voltage L l l output l g See 4 S Note N IOL = 1 A IOL = 1.3 A VF(K) O p clamp-diode Output l p di d fforward d voltage l g IF = 0.5 A IF = 1 A IOH IIH High-level output current IF = 1.3 A VOH = 50 V, IIL IR(K) Low-level input current ICC MIN High-level input current S Note See N 4 VOK = 50 V TYP† MAX UNIT – 0.9 – 1.5 V 0.2 0.35 0.4 0.7 0.5 0.9 1.1 1.9 1.3 2.2 1.4 VI = VIH VI = 0 to 0.8 V Output clamp-diode reverse current (at Y output) VR = 50 V, VO = 0 All outputs at high level (off) All outputs at low level (on) S Supply l current Two outputs at high level (off) and two outputs at low level (on) V V 2.4 100 µA 10 µA – 10 µA 100 µA 2 8 140 200 70 110 TYP MAX mA A † All typical values are at V CC = 5 V, TA = 25°C.
