DG300(A)/DG301(A)/DG302(A)/DG303(A) TTL Compatible CMOS Analog Switches
The DG300‑DG303 and DG300A‑DG303A families are CMOS dual‑ and quad‑channel analog switches that combine low power operation with fast switching times and superior DC and AC characteristics. On‑resistance is less than 50 Ω and the devices operate from ±5 V to ±18 V, supporting both single‑supply and dual‑supply configurations.
These switches are suitable for portable instruments, low‑power sample/hold circuits, power‑supply switching, programmable gain amplifiers, and process control. Key specifications include turn‑ON times as low as 150 ns, turn‑OFF times of 40 ns, and input logic levels compatible with TTL (0.8 V to 4.0 V).
