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 (10?max) is matched between switches to 1?max and is flat (1?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.

Applications Information
Power-Supply Sequencing and
Overvoltage Protection
Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause perma-nent damage to the devices.
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 sequenc-ing 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.
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 IN1 and IN2 all the way to the supply rails (i.e., to a
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 sup-ply 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.
