THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENTARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT 8-Channel / dual 4-Channel CMOS Analog MultiplexersDESCRIPTIONThe DG508B is an 8-Channel single-ended analogmultiplexer designed to connect one of eight inputs to acommon output as determined by a 3-bit binary address(A0, A1, A2). The DG509B is a dual 4-Channel differentialanalog multiplexer designed to connect one of fourdifferential inputs to a common dual output as determinedby its 2-bit binary address (A0, A1). Break-before-makeswitching action protects against momentary crosstalkbetween adjacent on channel conducts current equally well in bothdirections.

2 In the off state each channel blocks voltages upto the power supply rails. An enable (EN) function allows theuser to reset the multiplexer / demultiplexer to all switchesoff for stacking several devices. All control inputs,addresses (AX) and enable (EN) are TTL compatible over thefull specified operating temperature DG508B and DG509B are fabricated on an enhancedSG-II CMOS process that achieves improved performanceon: reduced charge injection, lower device leakage, andminimized parasitic capacitance. As the DG508, DG509 has a long history in the industry withmany suppliers offering copies - and in some casesimproved variations - with the best in class improvements,the vishay Siliconix new version of the DG508B, DG509 Bare the superior alternatives to what is currently for the DG508B, DG509B include high speedand high Precision data acquisition, audio signal switchingand routing, ATE systems, and avionics.

3 High performanceand low power dissipation make them ideal for batteryoperated and remote instrumentation DG508B and DG509B have the absolute maximumvoltage rating extended to 44 V. Additionally, single supplyoperation is also allowed. An epitaxial layer DG508B and DG509B are both available in 16-leadSOIC, TSSOP, PDIP, and miniQFN ( mm x mm)package options with extended temperature range of -40 Cto +125 more information, refer to vishay Siliconix DG508B,DG509B evaluation board Operate with single or dual power supply V+ to V- Analog signal swing range 44 V power supply maximum rating Extended operate temperature range:-40 C to +125 C Low leakage typically < 3 pA Low charge injection - QINJ = 2 pC Low power - ISUPPLY: 10 A TTL compatible logic > 250 mA latch-up current per JESD78 Available in SOIC16, TSSOP16, PDIP, and miniQFN16packages Superior alternative to: - ADG508A, DG508A, HI-508- ADG509A, DG509A, HI-509 Material categorization.
