1 G6B, G7B Precision 6-Channel/ual 8-Channel CMOS nalog Multiplexers ESCRIPTION The G6B and G7B are high performance analog multiplexers. Their ultra-low switch charge injection, low channel capacitance, and low leakage level allows them to achieve superior switching performance. The G6B is a 6-channel single-ended analog multiplexer designed to connect one of sixteen inputs to a common output as determined by a 4-bit binary address (,, 2, 3). The G7B is a dual 8-channel differential analog multiplexer designed to connect one of eight differential inputs to a common dual output as determined by its 3-bit binary address (,, 2). Break-before-make switching action protects against momentary crosstalk between adjacent channels. n on channel conducts current equally well in both directions. In the off state each channel blocks voltages up to the power supply rails. n enable () function allows the user to reset the multiplexer/demultiplexer to all switches off for stacking several devices. ll control inputs, addresses (x) and enable () are TTL compatible over the full specified operating temperature range. The G6B and G7B are fabricated on an enhanced SG-II CMOS process that achieves improved performance on: reduced charge injection, lower device leakage, and minimized parasitic capacitance. s the G6, G7 has a long history in the industry with many suppliers offering copies, and in some cases improved variations, with the best in class improvements, the Vishay Siliconix new version of the G6B, G7B are the superior alternatives to what is currently available. pplications for the G6B, G7B include high speed and high precision data acquisition, audio signal switching and routing, TE systems, and avionics. High performance and low power dissipation make them ideal for battery operated and remote instrumentation applications. The G6B and G7B have the absolute maximum voltage rating extended to 44 V. dditionally, single supply operation is also allowed. n epitaxial layer prevents latch-up. The G6B and G7B are both available in 28-lead SOIC and TSSOP package options with extended temperature range of -4 C to +2 C. For more information, refer to G6B, G7B evaluation board note.
