General Description
Maxim’s MAX312L/MAX313L/MAX314L analog switch­es feature low on-resistance (10Ω max) and 1.5Ω on­resistance matching between channels. These switches are +3V logic compatible when powered from ±15V or +12V supplies. The switches conduct equally well in either direction, and offer low leakage over temperature (2.5nA at +85°C).
The MAX312L/MAX313L/MAX314L are quad, single­pole/single-throw (SPST) analog switches. The MAX312L is normally closed (NC), and the MAX313L is normally open (NO). The MAX314L has two NC switches and two NO switches. All three devices operate from a single +4.5V to +36V supply or from dual ±4.5V to ±20V, and are available in 16-pin TSSOP, SO, and DIP packages.

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.

this data sheet.
Note 3: -40°C specifications are guaranteed by design. Note 4: ΔR

Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Note 6: Leakage parameters are 100% tested at maximum-rated hot temperature and guaranteed by correlation at +25°C. Note 7: Guaranteed by design. Note 8: Off-isolation = 20log

Applications Information
Low-Distortion Audio
The MAX312L/MAX313L/MAX314L, having very low R
ON
and very low RONvariation with signal amplitude, are well suited for low-distortion audio applications. The
Typical Operating Characteristics
show Total Harmonic Distortion (THD) vs. Frequency graphs for several signal amplitudes and impedances. Higher source and load impedances improve THD, but reduce off-isolation.
Off-Isolation at High Frequencies
In 50Ω systems, the high-frequency on-response of these parts extends from DC to above 100MHz with a typical loss of -2dB. When the switch is turned off, how­ever, it behaves like a capacitor, and off-isolation decreases with increasing frequency. (Above 300MHz, the switch actually passes more signal turned off than turned on.) This effect is more pronounced with higher source-and-load impedances.
Above 5MHz, circuit board layout becomes critical, and it becomes difficult to characterize the response of the switch independent of the circuit. The graphs shown in the
Typical Operating Characteristics
were taken using a
50Ω source and load connected with BNC connectors.
Power-Supply Sequencing-Free
Operation
Most CMOS switches require specific power-supply sequencing in order to prevent the devices from latching up. The older MAX312/MAX313/MAX314 devices require a proper power-supply sequence of V+, VL, V-, and so forth. Otherwise, it becomes necessary to add signal diodes to the circuit in order to protect it from potential latchups. The new MAX312L/MAX313L/MAX314L devices eliminate the need for a VLpin and permit the user to utilize any power-up sequence that is required. It is, however, important not to exceed the absolute maxi­mum ratings because stresses beyond the listed ratings may cause permanent damage to the devices.
