GENERAL DESCRIPTION
The ADG5408/ADG5409 are monolithic CMOS analog multi-
plexers comprising eight single channels and four differential
channels, respectively. The ADG5408 switches one of eight
inputs to a common output, as determined by the 3-bit binary
address lines, A0, A1, and A2. The ADG5409 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 enables or disables the device.
When EN is disabled, all channels switch off. The on-resistance
profile is very flat over the full analog input range, which ensures
good linearity and low distortion when switching audio signals.
High switching speed also makes the parts suitable for video
signal switching.
Each switch conducts equally well in both directions when on,
and each switch has an input signal range that extends to the
power supplies. In the off condition, signal levels up to the
supplies are blocked.

Trench isolation guards against latch-up. A dielectric trench
separates the P and N channel transistors thereby preventing
latch-up even under severe overvoltage conditions.

Dual-supply operation. For applications where the analog
signal is bipolar, the ADG5408/ADG5409 can be operated
from dual supplies up to ±22 V.
Single-supply operation. For applications where the analog
signal is unipolar, the ADG5408/ADG5409 can be operated
from a single rail power supply up to 40 V.

... TRENCH ISOLATION In the ADG5408/ADG5409, an insulating oxide layer (trench) is placed between the NMOS and the PMOS transistors of each CMOS switch. Parasitic junctions, which occur between the transistors in junction isolated switches, are eliminated, and the result is a completely latch-up proof switch. In junction isolation, the N and P wells of the PMOS and NMOS transistors form a diode that is reverse-biased under normal operation ...
