产品概述

The MAX4561/MAX4568/MAX4569 are low-voltage, ESD-protected analog switches. The normally open (NO) and normally closed (NC) inputs are protected against ±15kV electrostatic discharge (ESD) without latchup or damage, and the COM input is protected against 2.5kV ESD.

These switches operate from a single +1.8V to +12V supply. The 70Ω at 5V (120Ω at 3V) on-resistance is matched between channels to 2Ω max, and is flat (4Ω max) over the specified signal range. The switches can handle rail-to-rail analog signals. Off-leakage current is only 0.5nA at +25°C and 5nA at +85°C. The digital input has +0.8V to +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply. The MAX4561 is a single-pole/double-throw (SPDT) switch. The MAX4568 NO and MAX4569 NC are single-pole/single-throw (SPST) switches.

The MAX4561 is available in a 6-pin SOT23 package, and the MAX4568/MAX4569 are available in 5-pin SOT23 packages.
