... The charge pump, the transmitters, and the receivers. Charge-Pump Intersil’s new RS-232 family utilizes regulated on-chip dual charge pumps as voltage doublers, and voltage inverters to generate ±5.5V transmitter supplies from a V low as 3.0V. This allows these devices to maintain RS-232 compliant output levels over the ± ...
