MAX4635/MAX4636 19-1709 Rev 2 5/03 Fast, Low-Voltage, Dual 4 SPDT CMOS Analog Switches General Description Features The MAX4635/MAX4636 are fast, dual 4 single- Guaranteed On-Resistance pole/double-throw (SPDT) analog switches that operate 4 (max) +5V Supply with supply voltages from +1.8V to +5.5V. High switch- 5.5 (max) +3V Supply ing speeds, 1 on-resistance flatness, and low power Guaranteed Match Between Channels consumption make these devices ideal for audio/video, 0.2 (max) communications, and battery-operated devices. Guaranteed Flatness Over Signal Range Containing two independently controllable SPDT 1 (max) with +5V Supply switches in 10-pin MAX and 10-pin 3mm x 3mm thin Fast Switching Speeds QFN packages, the MAX4635/MAX4636 use little board 14ns (max) Turn-On Time space, and have low power consumption ensuring min- 6ns (max) Turn-Off Time imal impact on your power budget. The analog signal range extends to the supply rails. The MAX4635 has 1.8V Operation inverted logic compared to the MAX4636. 100 (typ) On-Resistance Over Temperature 56ns (typ) Turn-On Time Applications 17ns (typ) Turn-Off Time Battery-Powered Equipment +1.8V to +5.5V Single-Supply Operation Rail-to-Rail Signal Handling Relay Replacement Low Crosstalk: -67dB at 1MHz Audio and Video Signal Routing High Off-Isolation: -65dB at 1MHz Low-Voltage Data-Acquisition Systems THD: 0.1% Sample-and-Hold Circuits Communications Circuits Ordering Information PIN- TOP PART TEMP RANGE PACKAGE MARK MAX4635EUB -40C to +85C 10 MAX Rail-to-Rail is a registered trademark of Nippon Motorola, Ltd.

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.
