bu4066bc / bu4066bcf / bu4066bcfv standard ics quad analog switch bu4066bc / bu4066bcf / bu4066bcfv the bu4066bc, bu4066bcf, and bu4066bcfv each consist of four independent switches capable of controlling either digital or analog signals. when enable input (cont) is set to the "h" level, impedance is low (on status) between switch input and output, and when enable input (cont) is set to the "l" level, impedance is high (off status). as the bu4066bc has a good propagation characteristic, it can control large input voltage amplitudes. these switches can be used in analog and digital signal switching and in chopper modulator and demodulator circuits. ! ! ! ! absolute maximum ratings (ta=25 c) parameter symbol limits unit power supply voltage v dd v power dissipation mw operating temperature c storage temperature c input voltage v in v topr tstg pd ? 0.3~ + 18 ? 40~ + 85 ? 55~ + 150 ? 0.5~v dd + 0.5 1000(dip), 450(sop) 350(ssop) ! ! ! ! block diagram dip / sop / ssop swa out / in in / out swd out / in in / out swb in / out out / in swc out / in in / out v dd 14 i / o 1 1 c 1 13 c 4 12 i / o 4 11 10 o / i 3 9 i / o 3 8 o / i 1 2 o / i 2 3 i / o 2 4 c 2 5 c 3 6 v ss 7 o / i 4
