■PIN DESCRIPTION
The values in parentheses are standard.
■PRECAUTIONS ON USE
• Be sure to ground the pins of AVDD, DVDD, DVDDI, VRT, VRB, VR1, VR2, and VR3 via high-frequency capacitor.
Place the high-frequency capacitor as close as possible to the pin.
• To avoid gener ation of undesired current o wing to indetermination of internal logic, set CE to “H” at po w ering
on and input more than five clock pulses just after operation (CE: “H” → “L”).

■RECOMMENDED OPERATING CONDITIONS
WARNING: The recommended operating conditions are required in order to ensure the normal operation of the
semiconductor device. All of the device’s electrical characteristics are warranted when the device is
operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges. Operation
outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented on
the data sheet. Users considering application outside the listed conditions are advised to contact their
FUJITSU representatives beforehand.
