_________________General Description

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.

MAX4536/MAX4537/MAX4538 Quad, Low-Voltage, SPST Analog Switches with Enable __________Applications Information Power-Supply Considerations Overview The MAX4536/MAX4537/MAX4538 construction is typical of most CMOS analog switches. These devices have three supply pins: V+, V-, and GND. V+ and V- drive the internal CMOS switches and set the limits of the analog voltage on any switch. Reverse ESD-protection diodes are internally connected between each analog-signal pin, and both V+ and V-.
