TXS0104VBQAR

Translators, Level Shifters Overview

The TXS0104VBQAR is a 4-bit bidirectional voltage translator from Texas Instruments, designed for open-drain and push-pull applications. It operates with VCCA ranging from 1.65V to 3.6V and VCCB from 2.3V to 5.5V, requiring VCCA ≤ VCCB during operation. Maximum data rates reach 24Mbps for push-pull and 2Mbps for open-drain configurations. The device features integrated 10kΩ pullup resistors on all I/O ports and includes an output-enable (OE) pin referenced to VCCA. It supports ESD protection exceeding 2000V HBM on Port A and 5000V HBM on Port B. The component is housed in a 14-pin WQFN package.

Translators, Level Shifters Feature Summary

• Directionless translation architecture eliminates the need for external direction-control signals
• Integrated internal pullup resistors simplify circuit design for open-drain interfaces
• Flexible power-supply sequencing allows independent ramping of VCCA and VCCB rails
• High electrostatic discharge tolerance ensures robustness in sensitive environments

Translators, Level Shifters Applications

• Smartphone systems
• Tablet devices
• Handset electronics
• Desktop PC interfaces

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'BQA' corresponds to the WQFN 14-pin package configuration when ordering. Confirm that the supply voltage constraints are strictly maintained, ensuring VCCA does not exceed VCCB during active operation to prevent device malfunction. Ensure the OE pin is properly biased to ground during power-up sequences to maintain high-impedance states until supplies stabilize.

Translators, Level Shifters Selection Notes

Select this component when interfacing between low-voltage logic domains (1.8V/2.5V/3.3V) and higher voltage nodes (3.3V/5V) without requiring directional control logic. It is particularly suitable for open-drain buses where internal pullups reduce external component count. Consider the WQFN package size if board space is limited, and ensure the application environment meets the specified operating temperature range of -40°C to 85°C.

Translators, Level Shifters Part Context

This part belongs to the TXS0104V family of bi-directional level shifters. The 'BQA' suffix specifically denotes the 14-pin WQFN package variant. The base device provides four channels of voltage translation, distinguishing it from single-channel or eight-channel variants within the broader Texas Instruments translator portfolio.

Translators, Level Shifters Replacement Considerations

Direct substitutes include other parts from the TXS0104V family with different package suffixes such as PW, RUT, RGY, or D, provided the pinout compatibility matches the target PCB footprint.
