was4723q low on resistance, dual spdt analog switch descriptions the was4723q is a high performance, dual single pole double throw (spdt) analog switch that features ultra-low ron of 0.5 (typical) at 3.0v vcc. the was4723q operates over a wide vcc range of 2.3v to 4.5v and is designed for break-before-make operation. the select input is ttl-level compatible. was4723q is also featured with smart circuitry to minimize vcc leakage current even when the control voltage is lower than vcc supply voltage. this feature suits mobile handset applications by allowing direct interface with baseband processor general-purpose io with minimal battery consumption. in other word, there is no need of additional device to shift control level to be the same as that of vcc in real application. the was4723q is available in qfn1418-10l package. standard product is pb-free and halogen-free. features supply voltage : 2.3 ~ 4.5v ultra-low on resistance : 0.5 high off isolation : -81db @ 1khz crosstalk rejection : -83db @ 1khz -3db bandwidth : 50mhz rail-to-rail signal range break-before-make switching low quiescent current over an expanded control input range hbm jedec: jesd22-a114 io to gnd : 8kv power to gnd : 5kv applications cell phones, pda, digital camera and notebook lcd monitor, tv and set-top box audio and video signal routing other electronics equipments qfn1418-10l pin configuration (top view) 23 = device code * = month (a~z) marking order information device package shipping was4723q-10/tr qfn1418-10l 3000/reel&tape 1 2 3 4 5 6 7 8 9 10 com2 no1 com1 in1 nc1 gnd nc2 in2 vcc no2 1 of 8 4008-318-123 sales@twtysemi.com http://www.twtysemi.com product specification
