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 (A
0
,
A
1
, A
2
).
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 (A
0
, A
1
) 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 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 (A
X
) 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.
