MAX4684/MAX4685 0.5/0.8 Low-Voltage, Dual SPDT Analog Switches in UCSP General Description Benefits and Features The MAX4684/MAX4685 low on-resistance (R ), low- 12-Bump, 0.5mm-Pitch UCSP ON voltage, dual single-pole/double-throw (SPDT) analog NC Switch R ON switches operate from a single +1.8V to +5.5V supply. 0.5 max (+2.7V Supply) (MAX4684) The MAX4684 features a 0.5 (max) R for its NC 0.8 max (+2.7V Supply) (MAX4685) ON switch and a 0.8 (max) R for its NO switch at a +2.7V ON NO Switch R ON supply. The MAX4685 features a 0.8 max on-resistance 0.8 max (+2.7V Supply) for both NO and NC switches at a +2.7V supply. R Match Between Channels ON 0.06 (max) Both parts feature break-before-make switching action (2ns) with t = 50ns and t = 40ns at +3V. The digital R Flatness Over Signal Range ON OFF ON 0.15 (max) logic inputs are 1.8V logic-compatible with a +2.7V to +3.3V supply. +1.8V to +5.5V Single-Supply Operation Rail-to-Rail Signal Handling The MAX4684/MAX4685 are packaged in the chipscale 1.8V Logic Compatibility package (UCSP), significantly reducing the required PC Low Crosstalk: -68dB (100kHz) board area. The chip occupies only a 2.0mm x 1.50mm High Off-Isolation: -64dB (100kHz) area. The 4 x 3 array of solder bumps are spaced with a 0.5mm bump pitch.

Limit forward-diode current to maximum current rating. Note 2: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device can be exposed to during board level solder attach and rework. This limit permits only the use of the solder profiles recom- mended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and Convection reflow. Preheating is required. Hand or wave soldering is not allowed. 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.
