Vishay has announced that it is upgrading several Vishay Siliconix analog switch products to boost device performance and longevity. Replacing aging silicon technology with an advanced process that improves a range of device parameters while ensuring a useful lifetime well into the future, the move signals Vishay's continuing support for its analog switch and multiplexer product lines, which were pioneered in the 1960s, says the company. The new enhanced family of analog switches and multiplexers is designed on a high-density 18V process. The process not only offers an upgrade path for customers using Vishay's current 12V series products, but also enables the company to develop new precision analog products with higher complexity for sensitive analog designs. Key improvements to device specifications include an increase of the operating voltage from 12V to 16V; lower leakage, reduced parasitic capacitance, and faster switching speeds; and enhanced ruggedness, with higher latch-up current and ESD protection ratings. For example, the new DG9408E and DG9409E - drop-in upgrades for the popular DG9408 and DG9409 - feature 20% lower switch on-resistance, 10 % faster switching speeds, 35% lower parasitic capacitance, enhanced latch-up capability to 400mA, and guaranteed ESD protection to 2.5kV (human body model). Vishay is building the new devices on a mature process platform in an established facility with an eye towards shortening lead times and fully supporting the long life cycles of the analog switch products, which are widely used in such market applications as industrial control and automation systems, audio and video signal routing, instrumentation and test equipment, data acquisition, communication systems, and medical and healthcare systems.
