PI5A4765 also offers shunt switches connected to ground in order to dissipate capacitance that builds up on the unconnected nc or no line. as a result, reduction of popping and clicking sounds is achieved when switching between audio sources. pin confguration / block diagram (top view) nc 2 com 2 no 2 in 2 v cc c1 c2 c3 c4 b1 gnd b4 nc 1 com 1 no 1 in 1 a1 a2 a3 a4 v cc comp- comp0 b2 mute - + b3 v cc 3 shunt switch function table logic input (in x ) function 0 nc x connected to com x 1 no x connected to com x pin description pin # pin # csp name description a1, c1 no x data port (normally open) b1 v cc positive power supply a3, c3 nc x data port (normally closed) b4 gnd ground a2, c2 com x common output/data port b2 comp0 comparator output b3 comp- comparator input a4, c4 in x logic control note : 1. x = 1, or 2 note : 1. x = 1, or 2 ? power routing ? relay replacement ? audio/video signal routing ? pcmcia cards ? modems
