DS232AE+ PIN DESCRIPTIONS

VCC, GND: DC power is provided to the device on these pins. VCC is the +5-volt input.V+: Positive supply output (RS-232). V+ requires an external storage charge capacitor of at least 0.1 μF.A larger capacitor (up to 10 μF) can be used to reduce supply ripple.V-: Negative supply output (RS-232). V- requires an external storage capacitor of at least 0.1 μF. Alarger capacitor (up to 10 μF) can be used to reduce supply ripple.T1IN, T2 IN: Standard TTL/CMOS inputs for the RS-232 drivers. The inputs of unused drivers can be leftunconnected since each input has a 400 kΩ pullup resistor.T1OUT, T2 OUT: Driver outputs at RS-232 levels. Driver output swing meets RS-232 levels for loads up to3 kΩ. These driver outputs provide current necessary to meet RS-232 levels for loads up to 2500 pF.2 of 10
