... Negative Supply Output (RS232 Drivers). V – 2.5V). This pin requires an external charge storage capacitor C 0.1 F. Larger value capacitors may be used to reduce supply ripple. With multiple transceivers, the V – and V pins may be paralleled into common capacitors. LT1180A/LT1181A Slew Rate vs Load Capacitance 8 +SLEW 6 –SLEW 4 ...

... The driver outputs are protected against ESD to 10kV for human body model discharges. U ESD PROTECTIO The RS232 line inputs of the LT1180A/LT1181A have on- chip protection from ESD transients up to 10kV. The protection structures act to divert the static discharge safely to system ground. In order for the ESD protection to ...
