Overview
The TXS0101DRYR is a single-channel bidirectional voltage-level translator with auto-direction-sensing, housed in a DRY (SON-6) package. It supports VCCA from 1.65V to 3.6V and VCCB from 2.3V to 5.5V. Maximum data rates are 24Mbps for push-pull and 2Mbps for open-drain configurations. The device features integrated 10kΩ pullup resistors, Ioff support for partial-power-down modes, and an OE pin for high-impedance control.
Feature Summary
- Auto-direction sensing eliminates the need for external direction-control signals
- Integrated 10kΩ pullup resistors on both ports simplify open-drain circuit designs
- Supports partial-power-down operation via Ioff functionality
- No power-supply sequencing required between VCCA and VCCB rails
Applications
- Handsets
- Smartphones
- Tablets
- Desktop PCs
Procurement Notes
Verify the specific ordering suffix 'DRY' corresponds to the SON-6 package variant when sourcing. Confirm that the intended application operates within the specified voltage ranges of 1.65V to 3.6V on Port A and 2.3V to 5.5V on Port B. Ensure the OE pin is properly biased to enable or disable the translator as required by the system design.
Selection Notes
Select this component for applications requiring bidirectional translation between 1.8V, 2.5V, 3.3V, and 5V logic levels. It is suitable for interfacing open-drain drivers where internal pullups are desired. Consider the DRY package size if board space is limited. Verify that the maximum data rate requirements do not exceed 24Mbps for push-pull or 2Mbps for open-drain setups.
Part Context
This part belongs to the TXS0101 family of voltage translators. It shares functional characteristics with other members like TXS0101DRLR and TXS0101DBV but differs in physical packaging. The DRY suffix specifically denotes the NanoFree SON-6 package, which offers a compact footprint compared to SOT-23 or SC-70 variants.
Replacement Considerations
Direct substitutes include TXS0101DRLR and TXS0101DBV, which offer identical electrical performance but utilize different packages (SOT-5X3-6 and SOT-23-6 respectively). Ensure mechanical fitment is compatible before swapping.
