The DG408LE and DG508B are 8-channel single-ended Analogue Multiplexers designed to connect one of eight inputs to a common output.
The DG409LE and DG509B are dual 4-channel differential Analogue Multiplexers designed to connect one of four differential inputs to a common dual output.

The DG506B and DG507B 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 DG506B is a 16-channel single-ended analog multiplexer designed to connect one of sixteen inputs to a common output as determined by a 4-bit binary address (A0, A1, A2, A3). The DG507B 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 (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.
