ADG714/ADG715 are CMOS, low voltage serially controlled, octal SPST switches controlled via either a 2- or 3-wire serial interface. On resistance is closely matched between switches and very flat over the full signal range. Each switch conducts equally well in both directions.
The ADG714/ADG715 are CMOS octal SPST (single‑pole, single‑throw) switches that can be controlled via a 2‑wire (I²C‑compatible) or 3‑wire (SPI/QSPI/MICROWIRE‑compatible) serial interface. On power‑up all switches are off and the devices support daisy‑chaining through a serial data output (DOUT). They are offered in a compact 24‑lead TSSOP package and operate from a single 2.7 V‑5.5 V supply or a dual +2.5 V supply.
Key features include low on‑resistance (typ. 2.5 Ω), low leakage (≈100 pA), power‑on reset, fast switching (≈20 ns), and robust ESD protection. The parts are specified for industrial temperature ranges (‑40 °C to +85 °C) and include detailed timing, absolute‑maximum‑ratings, and pin‑function tables.

The ADG714 uses a 3‑wire serial interface that is compatible with SPI, QSPI, and MICROWIRE.
The shift‑register DOUT allows multiple ADG714 devices to be daisy‑chained on the same bus.
Typical on‑resistance is 2.5 Ω.
The devices operate from a single supply of up to 5.5 V (or a dual +2.5 V supply).
