Each of the four switches can handle analog and digital signals up to 6V peak bidirectionally. The DR suffix denotes SOIC-14 package in 2.5kpcs tape and reel.","working_principle":"Each switch consists of a CMOS transmission gate (parallel N-channel and P-channel MOSFETs) controlled by a digital input. When the control is high, both MOSFETs conduct, providing a low-impedance bidirectional path. The complementary MOSFETs ensure low and relatively flat on-resistance across the signal range. When the control is low, both MOSFETs are off, providing high-impedance isolation.","pin_description":"
