The an 8-channel single-ended analog multiplexer, is designed to connect one of eight inputs to a common output as determined a 3-bit binary address A1, A2). enable (EN) are TTL or CMOS compatible over the full specified operating temperature range.
The DG509A_MIL, a dual 4-channel analog multiplexer, is designed to connect one of four differential inputs to a common output as determined by its 2-bit binary address (A0, A1) logic. Break-before-make switching action protects against momentary shorting of the input signals.
Fabricated in the Vishay Siliconix Plus-40 process, the absolute maximum voltage rating is extended 44 V, allowing increased operating headroom for standard "15-V signal swings and operation with "20-V supplies. An epitaxial layer prevents latch up.
The DG508A_MIL/509A_MIL are available in hermetic packages. For plastic packages, use the DG408/409 as pin-for-pin replacements.
A channel in the on state conducts current equally well in both directions. In the off state each channel blocks voltages up to the power supply rails, normally 30 V peak-to-peak. An enable (EN) function allows for device selection when several multiplexers are used All control inputs, address (AX) and
For applications requiring address data latching, the DG528/529 is recommended. DG408/409 is recommended for higher precision applications. For wideband/video routing and multiplexing, the DG538A is recommended.
