DESCRIPTION

The DG508A_MIL, an 8-channel single-ended analog

multiplexer, is designed to connect one of eight inputs to a

The DG509A_MIL, a dual 4-channel analog multiplexer, is

designed to connect one of four differential inputs to a common

Break-before-make

switching

action

protects

against

momentary shorting of the input signals.

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

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.

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.
