MAX4647/MAX4648 are dual-supply single-pole/single-throw (SPST) switches. On-resistance is 25Ω max and flat (2Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. Off-leakage current is only 1nA max at +25°C. They conduct analog or digital signals equally well in either direction. The primary application areas are in the switching and routing of signals in telecommunications and test equipment. The MAX4647/MAX4648 are single SPST analog switches. The MAX4647 has one normally closed (NC) switch, and the MAX4648 has one normally open (NO) switch. These devices operate from a single +9V to +36V supply or from dual ±4.5V to ±20V supplies. The MAX4647/MAX4648 are available in tiny 6-pin SOT23 packages.
The MAX4647 and MAX4648 are dual‑supply single‑pole single‑throw (SPST) analog switches offered in a tiny 6‑pin SOT23‑6 package. They support a single +9 V to +36 V supply or dual ±4.5 V to ±20 V supplies and handle rail‑to‑rail analog signals. The MAX4647 provides a normally‑closed (NC) switch, while the MAX4648 provides a normally‑open (NO) switch.
Key electrical characteristics include a typical on‑resistance of 25 Ω max, flatness of 2 Ω over the signal range, off‑leakage of 1 nA, turn‑on/off times of about 100 ns, and operation from –40 °C to +85 °C. The device is suited for communications, test equipment, audio, and other signal‑routing applications. This manual is written in Chinese.
| On‑Resistance (RON) | 25 Ω max (typical 2 Ω flatness) |
|---|---|
| Off‑Leakage Current | 1 nA max at +25 °C |
| Package | 6‑pin SOT23‑6 |
The maximum on‑resistance is 25 Ω.
The off‑leakage current is limited to 1 nA at +25 °C.
Both devices are offered in a 6‑pin SOT23‑6 package.
