1 standard ics quad 2-input / 2-output analog switch BU9761FS the BU9761FS are analog switches with four circuits each, two for input and two for output. depending on the status of the select pin, the two input signals can be switched to either of two output pins. in addition, the en pin can be used to set the output status to high impedance. applications videos, movies, tvs, mini-component sets, radio cas- sette players, audio equipment, personal computers features 1) ultra-compact slim package. (ssop-a20) 2) low current dissipation. (i q = 1 m a max.) 3) equipped with output enable terminal. 4) low switching on resistance. (r on = 130 w ) 5) low dispersion in switching on resistance for the various channels.
