MAX4655MAX4658 19-1984 Rev 4 6/07 High-Current, 10, SPST, CMOS Analog Switches General Description Features Maxims MAX4655MAX4658 are medium-voltage High Continuous Current Handling CMOS analog switches with low on-resistance of 10 300mA (MAX4655/MAX4656) max, specifically designed to handle large switch cur- 150mA (MAX4657/MAX4658) rents. With a switch capability of up to 400mA peak cur- High Peak Current Handling rent and 300mA continuous current (MAX4655/ 400mA (MAX4655/MAX4656) MAX4656), and up to 300mA peak current and 150mA 300mA (MAX4657/MAX4658) continuous current (MAX4657/MAX4658), these parts 10 (max) On-Resistance (15V supplies) can switch loads as low as 25. They can replace reed relays with a million times the speed and virtually unlim- V Not Required L ited number of lifetime cycles. Normal power consump- 1 (max) R Flatness over Specified Signal ON tion is only 3mW, whether the switch is on or off. These Range parts are TTL/CMOS compatible and will switch any Rail-to-Rail Signal Handling voltage within its power-supply range. +12V Single Supply or 15V Dual Supply These are SPST (single-pole/single-throw) switches. Operation The MAX4655/MAX4657 are normally closed (NC), while the MAX4656/MAX4658 are normally open (NO). Pin Compatible with DG417, DG418 The difference between the MAX4655/MAX4656 and Ordering Information the MAX4657/MAX4658 is in the power dissipation of their packages. Refer to the Absolute Maximum Ratings TOP and the Electrical Characteristics. PART TEMP RANGE PIN-PACKAGE MARK The MAX4655MAX4658 power-supply range is from MAX4655ETA -40C to +85C 8 TDFN-EP* AKT 4.5V to 20V for dual-supply operation and +9V to +40V for single-supply operation. These switches can MAX4655EUA -40C to +85C 8 MAX AAAL operate from any combination of supplies, within a 40V MAX4655ESA -40C to +85C 8 SO V+ to V- range. They conduct equally well in either direc- MAX4656ETA -40C to +85C 8 TDFN-EP* AKU tion and can handle rail-to-rail analog signals. The off- MAX4656EUA -40C to +85C 8 MAX AAAM leakage current is only 1nA max at T = +25C.

Limit forward diode current to max- imum 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.
