19-1709; Rev 2; 5/03 Fast, Low-Voltage, Dual 4 Ω SPDTCMOS Analog SwitchesMAX4635/MAX4636General DescriptionFeatures The MAX4635/MAX4636 are fast, dual 4Ω single- ♦ Guaranteed On-Resistance pole/double-throw (SPDT) analog switches that operate 4 Ω (max) +5V Supply with supply voltages from +1.8V to +5.5V. High switch- 5.5 Ω (max) +3V Supply ing speeds, 1Ω on-resistance flatness, and low power ♦ Guaranteed Match Between Channels consumption make these devices ideal for audio/video, 0.2 Ω (max) communications, and battery-operated devices. ♦ Guaranteed Flatness Over Signal Range Containing two independently controllable SPDT 1 Ω (max) with +5V Supply switches in 10-pin µMAX and 10-pin 3mm x 3mm thin QFN packages, the MAX4635/MAX4636 use little board ♦ Fast Switching Speeds space, and have low power consumption ensuring min- 14ns (max) Turn-On Time imal impact on your power budget. The analog signal 6ns (max) Turn-Off Time range extends to the supply rails. The MAX4635 has ♦ 1.8V Operation inverted logic compared to the MAX4636. 100 Ω (typ) On-Resistance Over Temperature 56ns (typ) Turn-On Time________________________Applications17ns (typ) Turn-Off Time Battery-Powered Equipment ♦ +1.8V to +5.5V Single-Supply Operation Relay Replacement ♦ Rail-to-Rail® Signal Handling Audio and Video Signal Routing ♦ Low Crosstalk: -67dB at 1MHz ♦ High Off-Isolation: -65dB at 1MHz Low-Voltage Data-Acquisition Systems ♦ THD: 0.1% Sample-and-Hold Circuits Communications Circuits Ordering InformationPIN-TOPPARTTEMP RANGEPACKAGEMARKMAX4635 EUB -40°C to +85°C 10 µMAX — Rail-to-Rail is a registered trademark of Nippon Motorola, Ltd.
