Keypad Mulitplexer I/O Device

NLSF2500
Keypad Multiplexer
The NLSF2500 is a keyboard multiplexer fabricated in sub−micron
silicon CMOS Technology. The NLSF2500 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.
