General Description

The MAX4614/MAX4615/MAX4616 quad, low-voltage,

high-speed, single-pole/single-throw (SPST) analog

switches are pin compatible with the industry-standard

74HC4066/MAX4610 analog switches. On-resistance

(10Ω max) is matched between switches to 1Ω max

and is flat (1Ω max) over the specified signal range.

Each switch handles V+ to GND analog signal levels.

Maximum off-leakage current is only 1nA at T

= +25°C

and 6nA at T

= +85°C.

The MAX4614 has four normally open (NO) switches,

and the MAX4615 has four normally closed (NC)

switches. The MAX4616 has two NO switches and two

NC switches. These CMOS switches operate from a

single +2V to +5.5V supply. All digital inputs have

+0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-

logic compatibility when using a single +5V supply.
