ELM7SH126xA is bus buffer with 3-STATE output, which is suitable for battery-operated devices because of

its low voltage and ultra high speed operation. The low power consumption contributes to longer battery life,

which allows long time operation of devices. The internal circuit which provides high noise immunity and stable

output is composed of 3 stages, including buffered output.

• Cell phones

• Digital cameras

• Portable electrical appliances like PDA, etc.

• Computers and peripherals

• Digital electrical appliances like LCD TV sets, DVD recorders/players, STB, etc.

• Modification inside print board, adjustment of timing, solution to noise

• Power voltage change from 5V to 3V
