was4732d mic/gnd cross - point switch for eu/us headphone compatible application descriptions the was4732d is a 2x2 cross - point switch that is used to interchange the ground and mic connections on a headphone connector. the ground switch has an ultra - low ron of 0.1 ? ( typical ) to minimize voltage drop across it, preventing undesired increase in headphone ground reference voltage. the switch state is controlled via the sel input. when sel=high, gnd is connected to com2 and mic is connected to com1; when sel=low, gnd is connected to com1 and mic is connected to com2. an internal pull - down 2m ? resistor on sel input sets the default state of the switch . the was4732d is available in dfn2x2 - 6l package. standard product is pb - free and halogen - free. features ? supply volt age : 2.3 ~ 5.0v ? ultra - low ron for gnd switch : 100m ? ? low ron for mic switch : 4.5 ? ? break - before - make switching ? low q uiescent current over an expanded control input range ? esd rating (hbm jedec: jesd22 - a114) ? io to gnd : 8kv ? power to gnd : 5kv ? replace ts3a26746e with compatible pcb layout applications ? cell phone ? tablet ? others music players dfn2x2 - 6l pin configuration (top view) 47 32 = device code ** = year & week ( a~z) marking order i nformation device package shipping was4732d - 6/tr dfn2x2 - 6l 3000/reel&tape 1 2 3 4 5 6 s e l m i c g n d c o m 2 c o m 1 v c c 1 2 3 4 5 6 4 7 3 2 d a * * 1 of 7 4008-318-123 sales@twtysemi.com http://www.twtysemi.com product specification 1 2 3 4 5 6 s e l m i c g n d c o m 2 c o m 1 v c c 1 2 3 4 5 6 4 7 3 2 d a * *
