HEF4053 is an intergrated circuit of general analog switches, which is widely used in large screen and DLPs, home theaters, wireless phones, videodisc players, computers and their screens to shift signals, such as in Changhong 51PT28A DLP, Desay wireless phones and so on. 1.function features HEF4053 contains three lines of single-pole double-throw switches which are under control of signals output by microcomputers, by which the signals can be shifted and chosen. The internal circuit of its chips is listed in Figure 1-1.
