RS_232_port_with_four_pairs_of_inputs_outputs

Published:2009/7/19 22:20:00 Author:Jessie | From:SeekIC

This circuit shows two ICL232s that are combined to accommodate four pairs of inputs/outputs. Notice that each circuit requires two charge-pump capacitors C1/C2, but can share common reservoir capacitors C3/C4. Harris Semiconductors, Data Acquisition 1991 p 137.
