The MAX4551/MAX4552/MAX4553 are quad, low-volt- age, single-pole/single-throw (SPST) analog switches. Each switch is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup or damage. On-resistance (100Ω max) is matched between switch- es to 4Ω max, and is flat (8Ω max) over the specified signal range. Each switch can handle Rail-to-Rail® ana- log signals. The off-leakage current is only 1nA at +25°C and 10nA at +85°C. The MAX4551 has four normally closed (NC) switches, and the MAX4552 has four normally open (NO) switch- es. The MAX4553 has two NC and two NO switches. These CMOS switches can operate with dual power supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. They are fully specified for sin- gle +2.7V operation. All digital inputs have +0.8V and +2.4V logic thresh- olds, ensuring TTL/CMOS-logic compatibility when using ±5V or a single +5V supply.
The MAX4551, MAX4552 and MAX4553 are quad, low‑voltage, single‑pole/single‑throw (SPST) analog switches. Each device offers ±15 kV ESD protection, matched on‑resistance (≤100 Ω max, ≤4 Ω variation) and rail‑to‑rail signal handling. The MAX4551 provides four normally‑closed switches, the MAX4552 four normally‑open switches, and the MAX4553 two of each.
These CMOS switches operate from dual supplies of ±2 V to ±6 V or from a single supply of +2 V to +12 V. Digital inputs accept +0.8 V and +2.4 V logic thresholds, ensuring TTL/CMOS compatibility. Typical off‑leakage current is 1 nA at 25 °C, and the devices feature low power consumption (<1 µW).
