MAX4675/MAX4676 19-1747 Rev 0 7/00 3 Single SPST Analog Switches General Description Features The MAX4675/MAX4676 single analog switches feature 3 (max) R ON 3 (max) on-resistance (R ) and 0.7 flatness when ON 0.7 (max) R Flatness ON operating from dual 5V supplies. These switches can handle Rail-to-Rail analog signals. Off-leakage current Dual 2.7V to 5.5V or Single +2.7V to +5.5V is 0.1nA at T = +25C. The MAX4675/MAX4676 are A Supply Range ideal in low-distortion applications and are the pre- Off-Isolation ferred solution over mechanical relays in automated test equipment or applications where current switching -75dB at 1MHz, Dual Supply is required. They are more reliable than mechanical -65dB at 1MHz, Single Supply relays, have low power requirements (<1A), and are -3dB Bandwidth 250MHz available in a space-saving 6-pin SOT23 package. Rail-to-Rail Signal Handling The MAX4675 has a single normally open (NO) switch, and the MAX4676 has a single normally closed (NC) switch. The MAX4675/MAX4676 operate from either a single +2.7V to +5.5V or dual 2.7V to 5.5V supplies, mak- ing them ideal for use in digital card applications and single-ended 75 systems.

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. Note 1: Signals on NO, NC, COM, or IN exceeding V+ or V- will be clamped by internal diodes. Limit forward diode current to maxi- mum current rating. ELECTRICAL CHARACTERISTICSDUAL SUPPLIES (V+ = +5V 10%, V- = -5V 10%, GND = 0, V = +2.4V, V = 0.8V, T = T to T , unless otherwise noted.
