ADG608/ADG609,pdf datasheet (3

The ADG608 and ADG609 are monolithic CMOS analog multiplexers
comprising eight single channels and four differential
channels respectively, fully specified for ±5 V, +5 V and +3 V
power supplies. The ADG608 switches one of eight inputs to a
common output as determined by the 3-bit binary address lines
A0, A1 and A2. The ADG609 switches one of four differential
inputs to a common differential output as determined by the
2-bit binary address lines A0 and A1. An EN input on both devices
is used to enable or disable the device. When disabled, all
channels are switched OFF. All the address and enable inputs
are TTL compatible over the full specified operating temperature
range, making the parts suitable for bus-controlled systems
such as data acquisition systems, process controls, avionics and
ATEs since the TTL compatible address inputs simplify the digital
interface design and reduce the board space requirements.
