Maxim MAX4614CUD Low-voltage, high-speed, quad, spst cmos analog switch Datasheet

19-1501; Rev 0; 7/99
Low-Voltage, High-Speed, Quad, SPST
CMOS Analog Switches
____________________________Features
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 TA = +25°C
and 6nA at TA = +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/CMOSlogic compatibility when using a single +5V supply.
♦ Fast Switching Times
12ns tON, 10ns tOFF
♦ Pin Compatible with Industry-Standard
74HC4066/MAX4610
♦ Guaranteed On-Resistance
10Ω max (+5V supply)
20Ω max (+3V supply)
♦ Guaranteed Match Between Channels (1Ω max)
♦ Guaranteed Flatness Over Signal Range (1Ω max)
♦ <6nA Off-Leakage Current Over Temperature
(TA = +85°C)
♦ Rail-to-Rail® Signal Handling
♦ TTL/CMOS-Logic Compatible

Note 1: Signals on NO_, NC_, or COM_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to maximum 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.

V+
Proper power-supply sequencing is recommended for
all CMOS devices. Always apply V+ before applying
analog signals or logic inputs, especially if the analog
or logic signals are not current limited. If this sequencing is not possible, and if the analog or logic inputs are
not current limited to 20mA, add a small-signal diode
(D1) as shown in Figure 1. If the analog signal can dip
below GND, add D2. Adding protection diodes
reduces the analog signal range to a diode drop (about
0.7V) below V+ (for D1), and to a diode drop above
ground (for D2). Leakage is unaffected by adding the
diodes. On-resistance increases by a small amount at
low supply voltages. Maximum supply voltage (V+)
must not exceed 6V.

diode drop higher than the V+ pin, or to a diode drop
lower than the GND pin) is always acceptable.
Protection diodes D1 and D2 also protect against some
overvoltage situations. With Figure 1’s circuit, if the supply voltage is below the absolute maximum rating, and
if a fault voltage up to the absolute maximum rating is
applied to an analog signal pin, no damage will result.
Adding protection diodes causes the logic thresholds
to be shifted relative to the power-supply rails. This can
be significant when low supply voltages (+5V or less)
are used. With a +5V supply, TTL compatibility is not
guaranteed when protection diodes are added. Driving
