MAX4538：Quad, Low-Voltage, SPST Analog Switches with Enable

The MAX4536/MAX4537/MAX4538 are quad, low-voltage, single-pole/single-throw (SPST) analog switches with a common enable pin. They are pin compatible with the industry-standard 74HC4316. The MAX4536 has four normally open (NO) switches, and the MAX4537 has four normally closed (NC) switches. The MAX4538 has two NO switches and two NC switches. These switches operate from a +2V to +12V single supply, or from ±2V to ±6V dual supplies. On-resistance (200Ω max) is matched between switches to 4Ω (max) and is flat (10Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 1nA at +25°C and 10nA at +85°C. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply or dual ±5V supplies.
