ANALOG DEVICES LT1032CN#PBF RS232 / RS423 Line Driver, 250 Kbps, 5 to 15V Supply, 0 to 70 °C, PDIP-14

LT1032CN#PBF is a quad low power line driver. This RS232 and RS423 line driver that operates over a ±5V to ±15V range on low supply current and can be shut down to zero supply current. Output is fully protected from externally applied voltages of ±30V by both current and thermal limiting. Since the output swings to within 200mV of the positive supply and 600mV of the negative supply, power supply needs are minimized. Also included is a strobe pin to force all outputs low independent of input or shutdown conditions. Further, slew rate can be adjusted with a resistor connected to the supply. A major advantage of the LT1032 is the high impedance output state when off or powered down. Application includes RS232, power supply inverter, micropower interface, level translator.

• Supply current is 500µA typ (VON/active low OFF ? 2.4V, IOUT = 0, all outputs low)
• Zero supply current when shut down
• Outputs can be driven ±30V, thermal limiting
• Output �Open� when off (three-state)
• 10mA output drive, pinout similar to 1488
• Power supply leakage current is 1µA typ (VON/active low OFF ? 0.4V)
• Slew rate is 15V/µs typ (IRESPONSE = 0, RL = 3K, TA = 25°C)
• Response pin leakage is 1µA typ (VSUPPLY = ±6V, TA = 25°C)
• 14 lead PDIP package, operating temperature range from 0°C to 70°C
