Product Summary
The SF2500EX23 is a keyboard multiplexer fabricated in sub.micron silicon CMOS Technology. The SF2500EX23 is designed to operate over wide operating voltage, with minimum power consumption and very low voltage drop from VCC. The device saves dozens of active and passive components and permits operating voltage far lower than the standard diode scheme. The applications of the SF2500EX23 include Cell Phones, PDAs, MP3 players.
