DG508 CMOS Analog Multiplexer

DG508 Precision 8-Channel CMOS Analog Multiplexers

DG508B 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).  Break-before-make switching action protects against momentary crosstalk
between adjacent channels.
An on channel conducts current equally well in both directions. In the off state each channel blocks voltages up to the power supply rails. An enable (EN) function allows the user to reset the multiplexer / demultiplexer to all switches off for stacking several devices. All control inputs, addresses (AX) and enable (EN) are TTL compatible over the full specified operating temperature range.
