Low-Voltage, High-Speed, Quad, SPST
CMOS Analog Switches
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
A
= +25°C
and 6nA at T
A
= +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.

Note 1:
Signals on NO_, NC_, or COM_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to maxi-
mum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
