Monolithic CMOS Analog Multiplexers
General Description
Maxim’s DG506A/DG507A are monolithic CMOS analog
multiplexers. The DG506A is a single 16-channel (1 of
16) multiplexer and the DG507A is a differential 8-chan-
nel (2 of 16) multiplexer.
Both devices feature break-before-make switching.
Maxim guarantees that these multiplexers will not latch-
up if the power supplies are turned off with the input
signals still present as long as absolute maximum ratings
are not violated. The multiplexers operate over a wide
range of power supplies from Q4.5V to Q18V.
Compared to the original manufacturer’s devices,
Maxim’s DG506A/DG507A consume significantly less
power, making them ideal for portable equipment.
Maxim’s DG506A/DG507A meet or exceed the speci-
fications of, and are drop-in replacements for Intersil’s
IH6116 and IH6216, Siliconix’s DG506A and DG507A,
and Harris’ HI506 and HI507.
