General-purpose CMOS Logic IC Series (BU4S,BU4000B Series)
Single Gate CMOS Logic ICs <Analog Switch>
BU4S66G2 No. 09050JAT02
●Description The BU4S66G2 is a 1ch analog switch IC encapsulated in an SSOP5 package, and can replace 1 circuit of the general-purpose CMOS two-way analog switch BU4066B IC.
●Features 1) Low power consumption 2) Surface mount package (SSOP5) 3) Broad operating supply voltage range: 3V-16V 4) L-TTL2 and LS-TTL1 inputs can be driven directly 5) Function compatible with BU4066BC series (1ch). 6) Excellent linearity
●Applications Can be used as a digital/analog switch, ON/OFF switch, or changeover switch in a high speed line, with no deterioration of the analog signals. Connection to a low impedance circuit is possible, due to the low ON resistance.
