Description
PI3A2268 is a dual fast single-pole double throw (SPDT)
CMOS switch. It can be used as an analog switch or as a
low-delay bus switch. Specified over a wide operating
power supply voltage, 1.65V to 4.2V, the PI3A2268 has
an On-Resistance of 0.45Ω at +4.2V.
Break-before-make switching prevents both switches
being enabled simultaneously. This eliminates signal
disruption during switching.
Applications
 Cell Phones
 PDAs
 MP3 Players
 Portable Instrumentation
 Computer Peripherals
 Speaker Headset Switching
 Power Routing
 Relay Replacement
 Audio and Video Signal Routing
 PCMCIA Cards
 Modems
