s 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 generation of undesired current owing to indetermination of internal logic, set CE to "H" at powering on and input more than five clock pulses just after operation (CE: H L).

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. 6
