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.

Applications Information Low-Distortion Audio The MAX312L/MAX313L/MAX314L, having very low RON and very low RON variation 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. 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 VL pin 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. Chip Information TRANSISTOR COUNT: 92 PROCESS: CMOS 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. 8 _______________________________________________________________________________________ 10Ω, Quad, SPST, +3V Logic-Compatible Analog Switches V+ VIN_ SWITCH INPUT tr < 20ns tf < 20ns 50% LOGIC INPUT MAX312L MAX313L MAX314L V+ COM_ VCOM_ NO_ SWITCH OUTPUT OR NC_ 0 tOFF LOGIC INPUT VO CL 35pF RL 300Ω IN_ GND V- 0 V- VO 0.9VO SWITCH OUTPUT REPEAT TEST FOR EACH SWITCH.
