MAX4737/MAX4738/ 4.5 Quad SPST Analog Switches in UCSP MAX4739 General Description Benefits and Features The MAX4737/MAX4738/MAX4739 low-voltage, low on- USB 1.1 Signal Switching resistance (R ), quad single-pole/single throw (SPST) ON 2ns (max) Differential Skew analog switches operate from a single +1.8V to +5.5V -3dB Bandwidth: >300MHz supply. These devices are designed for USB 1.1 and Low 20pF On-Channel Capacitance audio switching applications. Low R ON The MAX4737/MAX4738/MAX4739 feature 4.5 R ON 4.5 (max) (+3V Supply) (max) with 1.2 flatness and 0.4 matching between 3 (max) (+5V Supply) channels. These new switches feature guaranteed operation from +1.8V to +5.5V and are fully specified 0.4 (max) R Match (+3V Supply) ON at 3V and 5V. These switches offer break-before-make 1.2 (max) R Flatness (+3V Supply) ON switching (1ns) with t <80ns and t <40ns at +2.7V. ON OFF <0.5nA Leakage Current at +25C The digital logic inputs are +1.8V logic compatible with a High Off-Isolation: -55dB (10MHz) +2.7V to +3.6V supply. Low Crosstalk: -80dB (10MHz) These switches are packaged in a chip-scale package Low Distortion: 0.03% (UCSP), significantly reducing the required PC board area. The chip occupies only a 2mm x 2mm area and has +1.8V CMOS-Logic Compatible a 4 x 4 bump array with a bump pitch of 0.5mm. These Single-Supply Operation from +1.8V to +5.5V switches are also available in a 14-pin TSSOP and a Rail-to-Rail Signal Handling 16-pin thin QFN (4mm x 4mm) package.

Limit forward-diode current to maxi- mum 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.
