Vishay DG9251, DG9252, DG9253, DG9236 CMOS analog switch and multiplexers

Vishay Intertechnology Inc. expanded its 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 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). Applications include 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 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 °C to + 85 °C.

Pricing: for U.S. delivery begins at $0.95 per piece for the DG9251 and DG9236 in 1,000-piece quantities and $1.25 per piece for the DG9252 and DG9253.

Availability: Samples and production quantities are available now, with lead times of 10 weeks for standard orders.
