DG508ABK

The DG508A is a CMOS monolithic 8-channel analog multiplexer that can also function as a demultiplexer. It features an enable input, and when the enable input is high, a channel is selected by the address inputs. When low, all channels are off. A channel in the ON state conducts current equally well in both directions, and in the OFF state, each channel blocks voltages up to the supply rails.

Key features include low power consumption, TTL and CMOS-compatible address and enable inputs, a 44V maximum power supply rating, high latch-up immunity, and break-before-make switching. The DG508A is pinout compatible with industry-standard devices. It operates over a temperature range of -25°C to +85°C and comes in a 16-lead CERDIP package.

This analog switch is suitable for applications such as data acquisition systems, communication systems, and signal multiplexing/demultiplexing. The part number DG508ABK is noted as not recommended for new designs, with DG408 suggested as a replacement.
