19-1505; Rev 0; 7/99 2.5Ω, Dual, SPST, CMOS Analog Switches Features The MAX4667/MAX4668/MAX4669 dual analog switches feature low on-resistance of 2.5Ω max. On-resistance is matched between switches to 0.5Ω max and is flat (0.5Ω max) over the specified signal range. Each switch can handle Rail-to-Rail® analog signals. The off-leakage current is only 5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test equipment or applications where current switching is required. They have low power requirements, use less board space, and are more reliable than mechanical relays. The MAX4667 has two normally closed (NC) switches, the MAX4668 has two normally open (NO) switches, and the MAX4669 has one NC and one NO switch that guarantee break-before-make operation. These switches operate from a +4.5V to +36V single supply or from ±4.5V to ±20V dual supplies. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using ±15V supplies or a single +12V supply. ♦ Low On-Resistance (2.5Ω max) ♦ Guaranteed RON Match Between Channels (0.5Ω max) ♦ Guaranteed RON Flatness over Specified Signal Range (0.5Ω max) ♦ Guaranteed Break-Before-Make (MAX4669) ♦ Rail-to-Rail Signal Handling ♦ Guaranteed ESD Protection >2kV per Method 3015.7 ♦ +4.5V to +36V Single-Supply Operation ±4.5V to ±20V Dual-Supply Operation ♦ TTL/CMOS-Compatible Control Inputs Ordering Information PART MAX4667CSE MAX4667CPE MAX4667ESE MAX4667EPE Applications Reed Relay Replacement PBX, PABX Systems Test Equipment Audio-Signal Routing Communication Systems Avionics TEMP.

Limit the 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.

Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with supply pins (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop above V-, but does not affect the devices’ low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed 44V. These protection diodes are not recommended when using a single supply. Off-Isolation at High Frequencies With the N.C. pins connected to GND, 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. 8 FUNCTION MAX4667 No Connection. Not internally connected. Connect to GND as low impedance to improve on/off-isolation. Logic-Control Digital Inputs Negative Analog Supply Voltage Input. Connect to GND for single-supply operation. Ground Analog Switch, Common Terminals 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 to a circuit board deemed “average”; that is, designed with isolation in mind, but not using stripline or other special RF circuit techniques. For critical applications above 5MHz, use the MAX440, MAX441, and MAX442, which are fully characterized up to 160MHz. +15V MAX4667 MAX4668 MAX4669 D1 V+ * * * * NO_/NC_ COM_ VD2 -15V * INTERNAL PROTECTION DIODES Figure 1.
