Intersil Unveils ISL43143/44/45 MightyMUX ICs

Intersil Corp. (Milpitas, CA) announced three new additions to its MightyMUX™ high-performance, low-voltage, analog switch line, the ISL43143, ISL43144 and ISL43145, which each contain four single-pole single-throw (SPST) analog switches operating below 15V. The near-chip-scale, 4mm x 4mm, quad-flat-no-lead (QFN) package offers significant savings in board space. Targeted applications include high-precision equipment used for medical, communications and testing.

The ISL43143, ISL43144 and ISL43145 have the flexibility to operate from a +2V to +12V single supply or from a ±2V to ±6V dual supply. R(ON) is less than 25 Ohms, at ±5V and 25°C, and R(ON) flatness is less than 5 Ohms guaranteed across input voltage and industrial temperature. The near-chip-scale, 16-pad, 4mm x 4mm, QFN package greatly conserves board space, occupying 50% less real estate than the TSSOP. A 16-lead, TSSOP package option is also available.

The ISL43143, ISL43144 and ISL43145 are available now. Pricing per IC in quantities of 100 to 999 units is $0.68 for the ISL43143IR, ISL43144IR and ISL43145IR in QFN packages; and $0.65 for the ISL43143IV, ISL43144IV and ISL43145IV in TSSOP packages. Both the QFN and TSSOP packages are rated for a temperature range of –40°C to +85°C and are available on tape and reel.
