DESCRIPTION
The DG508A_MIL, an 8-channel single-ended analog
multiplexer, is designed to connect one of eight inputs to a
common output as determined by a 3-bit binary address (A0,
A1, A2).
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.
enable (EN) are TTL or CMOS compatible over the full
specified operating temperature range.
Fabricated in the Vishay Siliconix Plus-40 process, the
absolute maximum voltage rating is extended to 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.
