DS229
NOTE: C5 is a recommended decoupling capacitor which is the same value as C1, C2, C3, and C4.
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.
