A rate of 20 kbits/s can be transmitted with a full 2500-pF load. Other applications are in data-transmission systems using relatively short single lines, in level translators, and for driving MOS devices. The logic input is compatible with most TTL families. Operation is from 12-V and –12-V power supplies. The SN75150 is characterized for operation from 0°C to 70°C. logic symbol† S 1 logic diagram (positive logic) 1A 2 2A S EN 3 7 1Y 6 1A 1 2 2Y 2A 3 † This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. Voltage values are with respect to network ground terminal. 2. Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability. 3. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length of zero. recommended operating conditions VCC+ VCC– Supply voltage MIN NOM MAX 10.8 12 13.2 – 10.8 – 12 – 13.2 UNIT V High-level input voltage, VIH 2 5.5 V Low-level input voltage, VIL 0 0.8 V Driver output voltage, VO Operating free-air temperature, TA 0 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 ± 15 V 70 °C 3 SN75150 DUAL LINE DRIVER SLLS081C – JANUARY 1971 – REVISED JUNE 1999 electrical characteristics over recommended operating free-air temperature range, VCC± = ±13.2 V (unless otherwise noted) PARAMETER TEST CONDITIONS VOH High-level output voltage VCC + = 10.8 V, VIL = 0.8 V, VOL Low-level output voltage (see Note 4) VCC + = 10.8 V, VIH = 2 V, IIH High level input current High-level IIL Low level input current Low-level Data input Strobe input Data input Strobe input VCC – = – 10.8 V, RL = 3 kΩ to 7 kΩ VCC – = – 10.8 V, RL = 3 kΩ to 7 kΩ MIN TYP† 5 8 VI = 2 2.4 4V VI = 0 0.4 4V VO = 25 V VO = – 25 V IOS Short circuit output current‡ Short-circuit ICCH + ICCH – Supply current from VCC +, high-level output VO = 0, VO = 0, Supply current from VCC –, high-level output VI = 3 V VI = 0 MAX V –8 –5 1 10 2 20 –1 – 1.6 –2 – 3.2 2 8 –3 –8 10 15 30 – 10 – 15 – 30 VI = 0,, RL = 3 kΩ,, TA = 25°C UNIT V µA mA mA 10 22 mA –1 – 10 mA ICCL + Supply current from VCC +, low-level output 8 17 mA VI = 3 V, RL = 3 kΩ, TA = 25°C ICCL – Supply current from VCC –, low-level output –9 – 20 mA † All typical values are at VCC + = 12 V, VCC – = – 12 V, TA = 25°C. ‡ Not more than one output should be shorted at a time.
