| Standard ICs Single analog switch BU4S66 The BU4S66 is an ultra-compact IC with one circuit of the bi-directional analog switch BU4066B built into an SMP package. Setting the enable input (CONT) to the "H" level sets the impedance between the switch input and the output pins low (ON state) and setting CONT to the "L" level sets the impedance high (OFF state). *Features dissipation. 1) Low current 2) Super-mini mold package designed for surface mounting. 3) Wide range of operating power supply voltage. 4) Direct drive of 2 L-TTL inputs and 1 LS-TTL input. *Block diagram VDD 5 CONT 4 1 I/O 2 O/I 3 VSS 1 Standard ICs BU4S66 *Absolute maximum ratings (Ta = 25C) Parameter Power supply voltage Power dissipation Input current Operating temperature Storage temperature Input voltage Symbol VDD Pd IIN Topr Tstg VIN Limits VSS - 0.3 ~ VSS + 18 170 10 - 40 ~ + 85 - 55 ~ + 150 VSS - 0.3 ~ VDD + 0.3 Unit V mW mA C C V 1 These values indicate the range limits of the voltage that can be applied to each pin without destroying it.
