TXB0108: Power-on ramp rate

Takahiro Saito

Part Number: TXB0108

Hi Team,

As shown in Power-Up 3-State (PU3S) Circuits in TI Standard Logic Devices, other TI logic families has the data-sheet-recommended operating conditions for the VCC ramp rate. Does TXB0108 has a recommended Vcc power-on ramp rate?

Regards,

Hi Saito-san,

The TXB0108 does not have the Power-Up 3-State feature or a specification for power-on ramp rate.

In section 10 Power Supply Recommendations of the datasheet, there is a power supply sequencing recommendation including a mention of what to do with the OE pin to ensure the device remains in a high-impedance state during power on.

Thanks Emrys,

I see. I understand that the TXB0108 accepts any power-on ramp rate. If you have recommendation of power on ramp rate , for this device, please let me know.
