Other Parts Discussed in Thread: TXB0304
Datasheets shows when VCCA is on and VCCB is off, its IO port disables. Does “disable” mean high-Z? customer concern that is there any leakage when VCCB is off.
What is the difference in TXB0108 and TXB0304?

Hello Peter,
Disable means high-Z. You are correct.
Under partial power down conditions, the outputs are also disabled and put into a high-Impedance state. This feature is referred to as VCC isolation. If VCCB = 0 V, the A-port is disabled. Likewise, if VCCA = 0V, the B-port will be disabled.
Other than the channel count difference, the major differences include the following:
Lower voltage range for the TXB030X devices - down to 0.9V
Higher VCCB voltage range for TXB010X - up to 5.5V
The VCCA must be less than or equal to VCCB in TXB010X, whereas in the TXB030X devices, either the VCCA or VCCB can be a higher voltage.
Hope this helps!
Best,
Michael
