CMOS analog switch and multiplexers provide low-voltage logic compatibility down to 1.4-V
October 17, 2011 // Paul Buckley
Vishay Intertechnology, Inc., has expanded the company DG92xx family of CMOS analog switching and multiplexer products with the introduction of four new devices designed for 2.7 V to 16 V single-supply or ± 2.7 V to ± 8 V dual-supply operation. The new devices combine their wide voltage range operation with compact package sizes and low-voltage logic compatibility for high-speed, high-precision switching applications.
The products released include a dual SPDT analog switch (DG9236), an 8-channel multiplexer (DG9251), a dual 4-channel multiplexer (DG9252), and a triple 2-channel multiplexer (DG9253). The new devices are optimized for touch panels, tablets, data acquisition, healthcare, instrumentation, and automation equipment.
The DG9251, DG9252, and DG9253 are fully specified at +16 V, +5 V and ±5 V. Compatible with CMOS and GPIO control signals, the devices’ control inputs have guaranteed 1.4 V logic high when operating from +5 V or ±5 V supplies, and 1.65 V logic high when operating from a +16 V supply. For CMOS/TTL microprocessor control signals, the DG9236 has a guaranteed 1.8 V logic high when operating from a +16 V power supply.
The three multiplexers are offered in the compact 1.8 mm by 2.6 mm miniQFN-16 package, while the DG9236 analog switch is offered in the 1.4 mm by 1.8 mm miniQFN-10 package with a low 0.55 mm profile. The devices’ plastic miniQFN packages are the smallest in the industry, and are comparable to WCSP type packages.
At −3 dB, the multiplexers offer a bandwidth of 314 MHz (DG9251), 449 MHz (DG9252), and 480 MHz (DG9253), and provide excellent isolation performance of -45 dB (typical) at 100 MHz and crosstalk of −48 dB (typical) at 100 MHz. The DG9236 features a bandwidth of 800 MHz and -70 dB crosstalk and −62 dB off-isolation at 10 MHz. All four devices are specified for an operating temperature range of -40 to + 85 °C.
Fabricated using Vishay’s proprietary CMOS process, the switch and multiplexers feature low parasitic capacitance, charge injection, leakage current, and power consumption. Designed to handle a wide range of analog and high-speed pulses, the devices conduct equally well in both directions, offer rail-to-rail analog signal handling, and can be used as both multiplexers and de-multiplexers.
As a committed partner to the community and the environment, all analog switches and multiplexers manufactured by Vishay Siliconix are compliant to RoHS directive 2002/95/EC and halogen-free in accordance to the IEC 61249-2-21 definition. The miniQFN family of packages features nickel-palladium-gold device terminations that meet all JEDEC standards for reflow and MSL rating.
Samples and production quantities of the new analog switch and multiplexers are available now, with lead times of 10 weeks for standard orders.

Internet of Things (IoT) manufacturer Ciseco has launched the Raspberry Pi ‘Wireless Inventors Kit’ (RasWIK), featuring 88 pieces to provide everything a Pi owner needs to follow a series of step-by-step projects or to create their own wireless devices, without the need for configuration or even writing code.
RasWIK has been designed to be highly accessible, demystifying the dark art of wireless and enabling anyone with basic computing skills to begin building wireless devices with a Raspberry Pi. You can create anything from a simple traffic light, to a battery monitor, or even a temperature gauge that sends data to the Xively IoT cloud so billions can access the data.This month, Ciseco is giving away twelve Raspberry Pi Wireless Inventors kits, worth £49.99 each for EETimes Europe's readers to win.
And the winners are...
In our previous reader offer, Farsens was giving away five kits for EEtimes Europe readers to evaluate its FenixVortex, Kineo and X1 wireless, battery free sensor tags.
Lucky winners include Mr A. Neil from the UK, Mr. E. Delvaux from Belgium, Mr Lengal from the Czech Republic, Mr H. Bijlsma from the Netherlands, and Mr G. Pfaff from Germany. All should be receiving their packages soon. Lets wish them some interesting findings with their projects.
