GENERAL DESCRIPTION
The ADG5204 is a complementary metal oxide semiconductor
(CMOS) analog multiplexer, comprising four single channels.
The ultralow capacitance and charge injection of these switches
make them ideal solutions for data acquisition and sample-and-
hold applications, where low glitch and fast settling are required.
Fast switching speed together with high signal bandwidth make
the ADG5204 suitable for video signal switching.
The ADG5204 is designed on a trench process, which guards
against latch-up. A dielectric trench separates the P and N
channel transistors, thereby preventing latch-up even under
severe overvoltage conditions.
The ADG5204 switches one of four inputs to a common output,
D, as determined by the 3-bit binary address lines, A0, A1, and
EN. Logic 0 on the EN pin disables the device. Each switch con-
ducts equally well in both directions when on, and each switch
has an input signal range that extends to the supplies. In the off
condition, signal levels up to the supplies are blocked. All switches
exhibit break-before-make switching action.

PRODUCT HIGHLIGHTS
1. 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.
2. Ultralow Capacitance and <1 pC Charge Injection.
3. Dual-Supply Operation.
For applications where the analog signal is bipolar, the
ADG5204 can be operated from dual supplies up to ±22 V.
4. Single-Supply Operation.
For applications where the analog signal is unipolar, the
ADG5204 can be operated from a single rail power supply
up to 40 V.
5. 3 V Logic-Compatible Digital Inputs.
VINH = 2.0 V, VINL = 0.8 V.
6. No VL Logic Power Supply Required.
