sn74lvc2g66-q1 www.ti.com sces829 C june 2011 dual bilateral analog switch check for samples: sn74lvc2g66-q1 1 features ? qualified for automotive applications ? 1.65-v to 5.5-v v cc operation ? inputs accept voltages to 5.5 v ? high on-off output voltage ratio ? high degree of linearity ? high speed, typically 0.5 ns (v cc = 3 v, c l = 50 pf) ? rail-to-rail input/output ? low on-state resistance, typically ? 6 ? (v cc = 4.5 v) description this dual bilateral analog switch is designed for 1.65-v to 5.5-v v cc operation. the sn74lvc2g66-q1 can handle both analog and digital signals. the device permits signals with amplitudes of up to 5.5 v (peak) to be transmitted in either direction. each switch section has its own enable-input control (c). a high-level voltage applied to c turns on the associated switch section. applications include signal gating, chopping, modulation or demodulation (modem), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems. ordering information t a package (1) orderable part number top-side marking (2) C 40 c to 125 c vssop C dcu reel of 3000 sn74lvc2g66qdcurq1 cay_ (1) package drawings, thermal data, and symbolization are available at www.ti.com/packaging .
