MAX4717/MAX4718 19-2627 Rev 2 9/05 4.5 /20 , 300MHz Bandwidth, Dual SPDT Analog Switches in UCSP General Description Features USB 1.1 Signal Switching Compliant The MAX4717/MAX4718 low-voltage, low on-resistance (TID = 4000231) (R ), dual single-pole/double throw (SPDT) analog ON switches operate from a single +1.8V to +5.5V supply. 2ns (max) Differential Skew These devices are designed for USB 1.1 and audio -3dB Bandwidth: > 300MHz switching applications. Low 15pF On-Channel Capacitance The MAX4717 features two 4.5 R (max) SPDT ON Single-Supply Operation from +1.8V to +5.5V switches with 1.2 flatness and 0.3 matching between 4.5 R (max) Switches (MAX4717/MAX4718) channels. The MAX4718 features one 4.5 R (max) ON ON 0.3 (max) R Match (+3.0V Supply) SPDT switch and one 20 R (max) SPDT switch. The ON ON 1.2 (max) Flatness (+3.0V Supply) 20 switch has a guaranteed matching and flatness of 0.4 and 1.2 , respectively. These switches offer break- 20 R (max) Switch (MAX4718) ON before-make switching (1ns) with t <80ns and t ON OFF 0.4 (max) R Match (+3.0V Supply) ON <40ns at +2.7V. The digital logic inputs are +1.8V logic 1.2 (max) Flatness (+3.0V Supply) compatible with a +2.7V to +3.6V supply. Rail-to-Rail Signal Handling These switches are packaged in a chip-scale package High Off-Isolation: -55dB (10MHz) (UCSP), significantly reducing the required PC board Low Crosstalk: -80dB (10MHz) area. The chip occupies only a 2.0mm 1.50mm area Low Distortion: 0.03% and has a 4 3 bump array with a bump pitch of 0.5mm. These switches are also available in 10-pin MAX and +1.8V CMOS-Logic Compatible 10-pin TDFN packages. < 0.5nA Leakage Current at +25C Applications Ordering Information USB 1.1 Signal Switching Circuits PIN/BUMP- TOP PART TEMP RANGE Battery-Operated Equipment PACKAGE MARK Audio/Video-Signal Routing MAX4717EUB -40C to +85C 10 MAX Headphone Switching MAX4717ETB -40C to +85C 10 TDFN-EP* ACV MAX4717EBC-T -40C to +85C 12 UCSP-12 ABH Low-Voltage Data-Acquisition Systems MAX4718EUB -40C to +85C 10 MAX Sample-and-Hold Circuits MAX4718ETB -40C to +85C 10 TDFN-EP* ACW Cell Phones MAX4718EBC-T -40C to +85C 12 UCSP-12 ABI PDAs *EP = Exposed paddle.

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.
