DG9408/DG9409 Vishay Siliconix Precision 8-Ch/Dual 4-Ch Low Voltage Analog Multiplexers FEATURES DESCRIPTION The DG9408/9409 uses BiCMOS wafer fabrication technology that allows the DG9408/9409 to operate on single and dual supplies. Single supply voltage ranges from 3 to 12 V while dual supply operation is recommended with ± 3 to ± 6 V. The DG9408 is an 8-channel single-ended analog multiplexer designed to connect one of eight inputs to a common output as determined by a 3-bit binary address (A0, A1, A2). The DG9409 is a dual 4-channel differential analog multiplexer designed to connect one of four differential inputs to a common dual output as determined by its 2-bit binary address (A0, A1). Break-before-make switching action to protect against momentary crosstalk between adjacent channels. As a committed partner to the community and the environment, Vishay Siliconix manufactures this product with lead (Pb)-free device terminations. The DG9408/9409 are offered in a QFN package that has a nickel-palladiumgold device terminations and is represented by the lead (Pb)-free “-E4” suffix. The nickel-palladium-gold device terminations meet all the JEDEC standards for reflow and MSL ratings. • 2.7 to 12 V single supply or ± 3 to ± 6 V dual supply operation • Low on-resistance - RON: 3.9 Ω typ. • Fast switching: tON - 42 ns, tOFF - 24 ns • Break-before-make guaranteed • Low leakage • TTL, CMOS, LV logic (3 V) compatible • 2000 V ESD protection (HBM) RoHS COMPLIANT BENEFITS • • • • High accuracy Single and dual power rail capacity Wide operating voltage range Simple logic interface APPLICATIONS • • • • • • • Data acquisition systems Battery operated equipment Portable test equipment Sample and hold circuits Communication systems SDSL, DSLAM Audio and video signal routing FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG9409 QFN16 DG9408 QFN16 S1 A2 V- D S1b Db V- Da 16 15 14 13 16 15 14 13 S2 1 12 S5 S2b 1 12 S1a GND 2 11 S6 GND 2 11 S2a S3 3 10 EN S3b 3 10 EN S4 4 9 S7 S4b 4 9 S3a Decoder/Driver Decoder/Driver 5 6 7 8 5 6 7 8 A0 V+ A1 S8 A0 V+ A1 S4a Top View Document Number: 71870 S-80714-Rev.

Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing. e. Guaranteed by design, not subject to production test. f. VIN = input voltage to perform proper function. g. ΔRDON = RDON Max - RDON Min. h. Worst case isolation occurs on Channel 4 due to proximity to the drain pin. i. RDON flatness is measured as the difference between the minimum and maximum measured values across a defined Analog signal. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. www.vishay.com 6 Document Number: 71870 S-80714-Rev.
