Description
The DG506A, a 16-channel single-ended analog
multiplexer, is designed to connect one of sixteen inputs
to a common output as determined by a 4-bit binary
address (A0, A1, A2, A3). The DG507A, a differential
8-channel analog multiplexer, is designed to connect one
of eight differential inputs to a common differential
outputs as determined by its 3-bit binary address (A0, A1,
A2) logic. 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 multiplexers are used. All control
inputs, address (AX) and enable (EN) are TTL or CMOS
compatible over the full specified operating temperature
range.
The DG506A/507A are fabricated in the Siliconix
PLUS-40 process, which includes improved ESD
protection for ruggedness. An epitaxial layer prevents
latch up.
For wideband/video multiplexing, the DG536 is
recommended.
