描述 Description

CD4066BMS is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. It is pin for pin compatible with CD4016B, but exhibits a much lower on state resistance. In addition, the on-state resistance is relatively constant over the full input signal range.
