DG201A/DG211 are quad single-pole single-throw (SPST) analog switches with a power supply range of ±4.5V to ±18V.
The DG201A and DG211 are normally‑closed quad single‑pole single‑throw (SPST) CMOS analog switches that operate from ±4.5 V to ±18 V. They feature break‑before‑make switching, no V L supply requirement, and are suited for portable applications such as disk drives, test equipment, and communications systems.
Key electrical specifications include turn‑on/off times of 450 ns/600 ns for the DG201A and 500 ns/1000 ns for the DG211, typical ON‑resistance of 115 Ω, and power dissipation up to 755 mW in a TSSOP package. The devices are available in multiple package styles (DIP, SO, TSSOP, QFN) and include recommended over‑voltage protection using 1N4001 or 1N914 diodes.
