Procurement Notes
When requesting a quote for TXS0108E_Level-Shifter, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For MCU, processor and logic IC sourcing, package, operating voltage, temperature grade, speed or frequency grade, firmware or mask version, lifecycle status and programming requirements should be checked before approval.
FAQ
What type of device is TXS0108E_Level-Shifter?
The extracted datasheet facts identify TXS0108E as an 8-bit non-inverting bidirectional level translator for open-drain and push-pull applications. The CMS product label is TXS0108E_Level-Shifter in the Interface category.
Does this translator need a direction-control signal?
No. The datasheet facts state that no direction-control signal is needed because the device provides automatic bidirectional translation between the A-port and B-port logic domains.
What supply voltages are supported on each port?
The recommended A-port supply range is 1.4 V to 3.6 V with VCCA less than or equal to VCCB. The recommended B-port supply range is 1.65 V to 5.5 V.
What are the maximum data rates for TXS0108E?
The extracted facts list a maximum data rate of 110 Mbps for push-pull operation and 1.2 Mbps for open-drain operation. These ratings are operation-mode dependent.
What happens when OE is driven low?
When OE is low, all outputs are placed in the high-impedance state. The OE input is referenced to VCCA, with high-level and low-level thresholds defined as ratios of VCCA.
