On-Resistance Flatness at +25°C • Fast Switching: 10ns Max. • +1.5V to +3.6V Single-Supply Operation • TTL/CMOS-Logic Compatible • –25dB Off-Isolation at 100kHz • 1nA Max. Off-Leakage at +25°C • Packaging (Pb-free & Green available): – 5-pin Small Compact SOT-23 (T) – 6-pin TDFN (ZC) Applications • Cellular Phones • Communications Circuits • Battery-Operated Equipment • DSL Modems • Audio and Video Signal Routing • PCMCIA Cards Description PI3A4626 is a single-pole/single-throw (SPST) normally open (NO) analog switch that operates from a single +1.5V to +3.6V supply. The switch has 0.4Ω Max On-Resistance (RON), with 0.1Ω Max RON flatness over the analog signal range when powered from a +3.0V supply. Leakage currents are less than 2nA and fast switch- ing times are less than 10ns. To minimize PC board area use, the device is available in the ultra compact TDFN, and the small compact SOT-23 packages.

The algebraic convention, where most negative value is a minimum and most positive is a maximum, is used in this data sheet. 2. Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing. 3. Guaranteed by design. 4. ΔRON = RON max. - RON min. 5. Flatness is defined as the difference between the maximum and minimum value of On-Resistance measured. V µA 5 PS8714A 06/27/04 5 Page
