High-Speed, Single-Supply, Quad, SPST Analog Switches
General Description
The MAX4591/MAX4592/MAX4593 are high-speed, precision, quad, single-pole/single-throw (SPST) analog switches designed to operate at +12V or +15V. The MAX4591 has four normally closed (NC) switches, and the MAX4592 has four normally open (NO) switches. The MAX4593 has two NO and two NC switches. All three devices offer low leakage (100pA max) and fast switching speeds (tON 80ns, tOFF 45ns). With a +12V supply, the MAX4591/MAX4592/MAX4593 offer guaranteed 1 max channel-to-channel matching, 20 max on-resistance (RON), and 1.75 max RON flatness over the specified range. These switches are also fully specified for single +15V operation, with 16 max RON, 1.5 max RON match, and 1.5 max flatness. For low-voltage or dual-supply operation, refer to the MAX391 data sheet. These low-voltage switches also offer 5pC max charge injection, and electrostatic discharge (ESD) protection is greater than 2000V, per Method 3015.7.

Note 1: Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- 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.

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet. Note 3: Guaranteed by design. Note 4: RON = RON max - RON min. 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 +25C. Note 7: Off-isolation = 20log10 [VCOM (VNC or VNO)], VCOM = output, VNC or VNO = input to off switch. Note 8: Between any two switches.

Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the devices. Always sequence V+ on first, followed by the logic inputs. If power-supply sequencing is not possible, add a small signal diode in series with V+ for overvoltage protection (Figure 1). Adding a diode reduces the analog signal range to 1V below V+, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference between V+ and V- should not exceed 17V.
