LT1030 Quad Low Power Line Driver U DESCRIPTION FEATURES ■ ■ ■ ■ ■ ■ ■ ■ Low Operating Voltage ±5V to ±15V Supply Current: 500µA Zero Supply Current When Shut Down Outputs Can Be Driven ± 30V Output “Open” When Off (Three-State) Output Drive: 10mA Pinout Similar to 1488* Output of Several Devices Can Be Paralleled U APPLICATIONS ■ ■ ■ RS232 Driver Micropower Interface Level Translator The LT ® 1030 is an RS232 line driver that operates over a ±5V to ±15V range on low supply current and can be shut down to zero supply current. Outputs are fully protected from externally applied voltages of ±30V by current limiting. Since the output swings to within 200mV of the positive supply and 1V of the negative supply, power supply needs are minimized. A major advantage of the LT1030 is the high impedance output state when off or powered down, which allows several different drivers on the same bus. Our RS232 product line includes other high performance devices. The LT1039 is a triple low power driver/receiver with shutdown that can be powered from a 5V supply. The LT1080 is a 5V powered dual driver/receiver with on-chip ±9V power generator and shutdown. , LTC and LT are registered trademarks of Linear Technology Corporation. *Check compatability (some pins may be different).

Strobe pin input impedance is about 2k to ground. Leave open when not used. U U U PIN FUNCTIONS V –(Pin 1): Operates – 15V to – 2V. STROBE (Pin 13): Forces all outputs low. Drive with 3V. LOGIC INPUT (Pins 2, 5, 9, 12): Operate properly on TTL or CMOS levels. Output valid from (V – + 2V) ≤ VIN ≤ 15V. Connect to 5V when not used. V + (Pin 14): Positive supply 5V to 15V. OUTPUT (Pins 3, 6, 8, 11): Line drive outputs. ON/OFF (Pin 4): Shuts down entire circuit. Cannot be left open. For “normally on” operation, connect between 5V to 10V. GND (Pin 7): 2 Ground must be more positive than V –. 14 8 LT1030 1 7 1N4001 LT1030 • PF01 Note: As with other bipolar ICs, forward biasing the substrate diode can cause problems. The LT1030 will draw high current from V + to ground if the V – pin is open circuited or pulled above ground. If this is possible, connecting a diode from V – to ground will prevent the high current state. Any low cost diode can be used. LT1030 U W TYPICAL PERFORMANCE CHARACTERISTICS On Supply Current vs Temperature On Supply Current vs Supply Voltage 5.0 5.0 VSUPPLY = ±12V 4.5 100 3.0 2.5 2.0 1.5 1.0 3.5 SUPPLY CURRENT (µA) SUPPLY CURRENT (mA) 4.0 ALL OUTPUTS HIGH 3.5 ALL OUTPUTS HIGH 3.0 2.5 2.0 1.5 1.0 ALL OUTPUTS LOW 0.5 0 100 125 10 30 2.4 2.0 100 80 60 40 20 75 100 TEMPERATURE (°C) 125 5 10 1.4 MIN ON VOLTAGE 1.2 1.0 0.8 0.6 LT1030 • TPC05 SINKING 25 20 SOURCING 15 10 100 125 LT1332 • TPC06 25 –0.4 23 IOUT = 5mA 21 IOUT = 1mA 1.4 1.2 IOUT = –5mA 1.0 0.8 0.6 IOUT = –1mA SLEW RATE (V/µs) OUTPUT VOLTAGE REFERED TO SUPPLIES (V) 30 Slew Rate vs Temperature V+ –0.2 17 FALLING 15 13 RISING 11 9 0.2 7 100 125 VS = ±12V RL = 3K CL = 51pF VSLEW = ±8V 19 0.4 V– –75 –50 –25 0 25 50 75 TEMPERATURE (°C) 100 125 LT1030 • TPC06 Output Swing vs Temperature Current Limit vs Temperature 35 MAX OFF VOLTAGE (IOUT < 20µA) GND 25 50 75 –75 –50 –25 0 TEMPERATURE (°C) 15 ON/OFF PIN VOLTAGE (V) LT1030 • TPC04 5 25 50 75 –75 –50 –25 0 TEMPERATURE (°C) MAX OFF VOLTAGE (IOUT < 200µA) 1.6 0.2 –20 GND 0.01 50 1.8 0.4 0 25 RL = 3k 2.2 ON/OFF PIN VOLTAGE (V) ON/OFF PIN CURRENT (µA) OUTPUT LEAKAGE CURRENT (µA) OUTPUT FORCED TO 25V 125 Shutdown Voltage vs Temperature 120 OUTPUT FORCED TO –25V 75 100 TEMPERATURE (°C) LT1030 • TPC03 140 10 50 25 On/Off Pin Current vs Voltage VSUPPLY = ±12V 0.1 0.1 LT1030 • TPC02 Off Output Leakage vs Temperature 0 0 0.01 25 20 15 TOTAL SUPPLY VOLTAGE (V) LT1030 • TPC01 100 10 ALL OUTPUTS LOW 0.5 0 –75 –50 –25 0 25 50 75 TEMPERATURE (°C) OUTPUT CURRENT (mA) VSUPPLY = ±12V 4.5 4.0 SUPPLY CURRENT (mA) Off Supply Current vs Temperature 5 –75 –50 –25 0 25 50 75 TEMPERATURE (°C) LT1030 • TPC08 Information furnished by Linear Technology Corporation is believed to be accurate and reliable.
