WAS4899Q low on resistance, quad spdt analog switch descriptions the WAS4899Q is a high performance, quad, single pole double throw (spdt) analog switch that features ultra - low ron of 0.5 ? (typical) at 3.0v vcc. the WAS4899Q operates over a wide vcc ra nge of 2.3v to 4.5v and is designed for break - before - make operation. the select input is ttl - level compatible. WAS4899Q is also featured with s mart 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 v cc in real application. the WAS4899Q is available in qfn3x3 - 16l package. standard products are pb - free and halogen - free. features ? supply voltage : 2.3 ~ 4.5v ? ultra - low on resistance : 0.5 ? ? - 3db bandwidth : 40mhz ? rail - to - rail signal rang e ? break - before - make switching ? low q uiescent current over an expanded control input range applications ? cell phones, pda, digital camera and notebook ? lcd monitor, tv and set - top box ? audio and video signal routing ? other electronics equipments pin configuration (top view) wa4899 = device code yy = year code ww = week code marking order i nformation device package shipping WAS4899Q - 16/tr qfn3x3 - 16l 3000/reel&tape 1 a 0 a 1 no 4 com 4 c o m 1 nc 1 nc 3 no 2 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 com 2 n c 2 g n d n o 3 c o m 3 n o 1 v c c n c 4 gnd 17 1 of 8 4008-318-123 sales@twtysemi.com http://www.twtysemi.com product specification 1 a 0 a 1 no 4 com 4 c o m 1 nc 1 nc 3 no 2 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 com 2 n c 2 g n d n o 3 c o m 3 n o 1 v c c n c 4 gnd 17
