• The MB86831/832/833 can be used with a 5.0-V or 3.3-V interface.

5.0-V interface: VDD5 = 5.0 V, VDD3 = 3.3 V (two power supplies)

3.3-V interface: VDD5 = VDD3 = 3.3 V (single power supply)

• When the 3.3-V interface is used, all signals input to the MB86830 series must be 3.3 V because the MB86830

series cannot input 5.0-V signals with that interface.

• When the 5.0-V interface is used, the output fully swings at 5.0 V. Although the input is always defined by a

3.3-V power supply, it can also accept 3.3 V or more.

• When the 5.0-V interface is used, the MB86830 series requires two power supplies. Follow the procedures

below to turn on and off these power supplies:

Power-on procedure: VDD3 → VDD5 → signal

Shutdown procedure: Signal → VDD5 → VDD3

• The MB86834/836 requires two power supplies of VDDE (3.3-V system) and VDDI (2.5-V system). Follow the

procedures below to turn on and off these power supplies:

Power-on procedure: VDDI → VDDE→ signal

Shutdown procedure: Signal → VDDE → VDDI

• The MB86835 has two VDD, VDD3 and VDD5. Connect each of them to a 3.3-V power supply.

• The MB86834/835/836 uses only a 3.3-V interface; they cannot accept 5-V signals.

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.
