The DG381(A) family are general‑purpose CMOS analog switches that combine low power operation with fast switching times and low on‑resistance. They are compatible with TTL and CMOS logic, feature break‑before‑make switching, and can operate from a single supply of +5 V to +18 V. Applications include portable instruments, sample‑and‑hold circuits, power‑supply switching, programmable gain amplifiers, and process control.
The document lists absolute maximum ratings, electrical characteristics such as on‑resistance (<50 Ω), leakage currents, and switching times, as well as detailed pin configurations for dual, quad, SPST, SPDT, and DPST packages. Ordering information and mechanical dimensions for various DIP, SO, CERDIP, and metal‑can packages are also provided.
| Supply Voltage Range | +5 V to +18 V |
