LT1180
The LT1180/81 RS232 transceivers with on-chip charge pumps offer some unique features that greatly enhance serial interface performance. Like the LT1080 and LT1130 series transceivers, the LT1180 is fully compliant with all RS232 specifications. The LT1180 is unique since it utilizes a charge pump which oscillates at 150kHz to 200kHz—about twice the frequency of the standard transceivers. In addition to providing excellent current delivery capability, the high speed charge pump can operate with storage capacitors as small as 0.1μF.
