Product Overview
TXS0108E is an 8-bit, non-inverting bidirectional level translator from Texas Instruments in the Signal_Chain category. It provides automatic bidirectional translation without a direction-control input, supporting mixed-voltage interfaces where the A port operates from 1.4 V to 3.6 V and the B port operates from 1.65 V to 5.5 V, with VCCA less than or equal to VCCB.
For interface timing, the device supports up to 110 Mbps in push-pull applications and up to 1.2 Mbps in open-drain applications. The OE input is referenced to VCCA, and driving OE low places all outputs in the high-impedance state. Power supply sequencing is not required because either VCCA or VCCB may ramp first.
The available package set includes PW TSSOP-20, RGY VQFN-20, DGS VSSOP-20, RKS VQFN-20, ZXY UFBGA-20, and NME NFBGA-20 options. Operating free-air temperature is specified from -40°C to 85°C, with ESD ratings including ±2000 V HBM, ±1000 V CDM, and B-port IEC 61000-4-2 contact discharge to ±8000 V.

Procurement Notes
When requesting a quote for TXS0108E, 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 analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What type of device is the TXS0108E?
TXS0108E is an 8-bit non-inverting bidirectional voltage translator from Texas Instruments. It provides automatic bidirectional level translation, so a separate direction-control signal is not required for supported translation use.
What supply ranges does TXS0108E support?
The A-port recommended supply range is 1.4 V to 3.6 V with VCCA less than or equal to VCCB. The B-port recommended supply range is 1.65 V to 5.5 V.
What data rates are specified for TXS0108E?
The maximum data rate is 110 Mbps for push-pull applications. For open-drain applications, the specified maximum data rate is 1.2 Mbps.
How does the OE input control the outputs?
The OE input is referenced to VCCA. When OE is driven low, all outputs are placed in the high-impedance state, supporting controlled disable behavior across the translated ports.
