MAX4721/MAX4722/MAX4723 19-2632 Rev 0 10/02 4.5 Dual SPST Analog Switches in UCSP General Description Features USB 1.1 Signal Switching The MAX4721/MAX4722/MAX4723 low-voltage, low on- resistance (R ), dual single-pole/single throw (SPST) ON <2ns 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 15pF On-Channel Capacitance audio switching applications. Low R (max) Switches ON The MAX4721/MAX4722/MAX4723 feature 4.5 R ON 4.5 (max) (+3V Supply) (max) with 1.2 flatness and 0.3 matching between 3 (max) (+5V Supply) channels. These new switches feature guaranteed operation from +1.8V to +5.5V and are fully specified at 0.3 (max) R Match (+3V Supply) ON 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 ON OFF <0.5nA Leakage Current at T = +25C A +2.7V. The digital logic inputs are +1.8V logic compati- High Off-Isolation: -55dB (10MHz) ble with a +2.7V to +3.6V supply. Low Crosstalk: -80dB (10MHz) These switches are packaged in a chip-scale package (UCSP), significantly reducing the required PC board Low Distortion: 0.03% area. The chip occupies only a 1.52mm 1.52mm area +1.8V CMOS-Logic Compatible and has a 3 3 bump array with a bump pitch of Single-Supply Operation from +1.8V to +5.5V 0.5mm. These switches are also available in an 8-pin Rail-to-Rail Signal Handling MAX package.

Limit forward-diode current to maxi- mum 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.
