Intersil Releases MightyMUX ISL84684 Dual Switch

July 12, 2004 by Jeff Shepard

Intersil Corp. (Milpitas, CA) released its MightyMUX™ ISL84684 high-performance dual switch that provides enhanced performance and reliability to replace currently available devices. This is a true bi-directional, ultra-low resistance, low-voltage, dual single-pole double throw (SPDT) analog signal switch intended for use in cell phones, smart phones, PDAs and other portable battery-powered products.

The ISL84684 has two independent switches, allowing it to replace two discrete SPDT devices where space is critical. The ISL84684 is a guaranteed break-before-make dual SPDT switch IC that operates over a 1.65 V to 3.6 V supply range, making it suitable for alkaline, nickel-metal hydride, and lithium-ion and lithium-polymer battery-powered applications. The ISL84684 provides low R(ON) conduction resistance and each switch is a low 0.29 Ohms at 2.7 V and 0.4 Ohms at 1.8 V, which reduces signal loss to improve audio output levels in battery-powered, hand-held products. When operated from a 2.7 V supply, the ISL84684 switches have a typical R(ON) flatness and channel matching of 0.03 Ohms, making them suitable for use in low-distortion audio paths such as MP3 players in cell phones, and CD audio devices. Switching speed at a supply of 2.7 V is typically a fast 14 ns turn-on and 6 ns turn-off, reducing switching noise.

Pricing for the ISL84684IR (TDFN) in 100-unit to 999-unit quantities is $1 and $0.95 for the ISL84684IU (MSOP).
