The TXS0104EPWR is a 4bit bidirectional voltage level translator in a TSSOP14 package, designed to bridge signals between different logic voltage domains. This device supports autodirection sensing, allowing signals to pass between two voltage rails without the need for external direction control. The YF04E marking indicates the lot/version for this package variant, and the product is supplied as a 10piece lot. Key benefits Enables reliable interfacing between devices operating at different logic voltages without manual direction control Reduces component count by combining four independent levelshifting channels in a compact package Suitable for compact board layouts thanks to the TSSOP14 form factor Flexible twosupply operation (VCCA and VCCB) for broad compatibility across common logic families Ideal for rapid prototyping and development with mixedvoltage components Key attributes Functionality: 4channel bidirectional voltage level translator with autodirection sensing Compatibility: Interfaces logic signals between two voltage domains (VCCA and VCCB) Package: TSSOP14 Configuration: 4 translation channels readily usable for digital signals Marking/ID: YF04E variant label noted on the device Quantity per package: 10 pieces per lot Applications and use cases Microcontroller to peripheral interfacing: Connect a 3.3V microcontroller to a 5V sensor, EEPROM, or peripheral without voltagelevel mismatches Mixedvoltage digital signal routing: Translate control and data lines between hosts and peripherals operating at different logic voltages in embedded systems Development and prototyping: Simplify board design by using a single fourchannel translator to bridge multiple voltage domains in a compact footprint Notes on use Ensure proper voltages on VCCA and VCCB within the device's operating range and follow standard PCB practices for clean signal integrity Use for general digital signal translation where bidirectional data flow is required and automatic direction sensing is advantageous Suitable for projects requiring a compact, lowpartcount solution to couple devices across voltage domains Package and ordering details Package: TSSOP14 Part: TXS0104EPWR Quantity: 10 pieces per package Marking: YF04E Brand alignment: Texas Instruments TXS0104 family with generalpurpose, bidirectional level translating capabilities This description reflects the product's core features and typical use cases for the TXS0104EPWR in a TSSOP14 package as a 4bit bidirectional voltage level translator, supplied in a 10piece lot.
