DG508B, DG509B www.vishay.com Vishay Siliconix Precision 8-Channel / Dual 4-Channel CMOS Analog Multiplexers DESCRIPTION FEATURES The DG508B is an 8-channel single-ended analog Operate with single or dual power supply multiplexer designed to connect one of eight inputs to a V+ to V- analog signal swing range common output as determined by a 3-bit binary address 44 V power supply maximum rating (A , A , A ). The DG509B is a dual 4-channel differential 0 1 2 Extended operate temperature range: analog multiplexer designed to connect one of four -40 C to +125 C differential inputs to a common dual output as determined by its 2-bit binary address (A , A ). Break-before-make 0 1 Low leakage typically < 3 pA switching action protects against momentary crosstalk Low charge injection - Q = 2 pC INJ between adjacent channels. Low power - I : 10 A SUPPLY An on channel conducts current equally well in both TTL compatible logic directions. In the off state each channel blocks voltages up > 250 mA latch-up current per JESD78 to the power supply rails. An enable (EN) function allows the user to reset the multiplexer / demultiplexer to all switches Available in SOIC16, TSSOP16, PDIP, and miniQFN16 off for stacking several devices. All control inputs, packages addresses (A ) and enable (EN) are TTL compatible over the X Superior alternative to: full specified operating temperature range. - ADG508A, DG508A, HI-508 The DG508B and DG509B are fabricated on an enhanced - ADG509A, DG509A, HI-509 SG-II CMOS process that achieves improved performance Material categorization: for definitions of compliance on: reduced charge injection, lower device leakage, and please see www.vishay.com/doc 99912 minimized parasitic capacitance. As the DG508, DG509 has a long history in the industry with BENEFITS many suppliers offering copies - and in some cases Reduced switching errors improved variations - with the best in class improvements, Reduced glitching the Vishay Siliconix new version of the DG508B, DG509B are the superior alternatives to what is currently available. Improved data throughput Applications for the DG508B, DG509B include high speed Reduced power consumption and high precision data acquisition, audio signal switching Increased ruggedness and routing, ATE systems, and avionics. High performance Wide supply ranges ( 5 V to 20 V) and low power dissipation make them ideal for battery operated and remote instrumentation applications. APPLICATIONS The DG508B and DG509B have the absolute maximum Data acquisition systems voltage rating extended to 44 V. Additionally, single supply Audio and video signal routing operation is also allowed. An epitaxial layer prevents latch-up. ATE systems The DG508B and DG509B are both available in 16-lead Medical instrumentation SOIC, TSSOP, PDIP, and miniQFN (1.8 mm x 2.6 mm) package options with extended temperature range of -40 C to +125 C.
