TXS0108EQDGSRQ1

Overview

The TXS0108EQDGSRQ1 is an automotive-grade, eight-channel bidirectional voltage-level translator manufactured by Texas Instruments. It utilizes CMOS logic and transmission gate input technology to facilitate signal translation between different voltage domains. The device supports data rates of up to 110 Mb/s and features a propagation delay of 745 ns. It operates within a supply voltage range of 1.4 V to 5.5 V and maintains a low operating supply current of 8 uA. Designed for robust performance, it functions across an extended temperature range from -40°C to +125°C. The component is housed in a VSSOP-20 surface-mount package and holds AEC-Q100 qualification for automotive applications.

Feature Summary

• Provides bidirectional voltage level translation for eight independent channels using transmission gate technology.
• Features automatic direction detection to manage signal flow without explicit direction control pins.
• Qualified for automotive environments with AEC-Q100 certification and operation up to 125°C.

Applications

• Interfacing microcontrollers with peripheral devices operating at different voltage levels in automotive systems.
• Connecting I2C or SPI buses where mixed voltage domains exist within electronic control units.
• Level shifting signals between low-voltage processors and higher-voltage sensors or actuators.

Procurement Notes

Verify the specific suffix 'DGSR' corresponds to the VSSOP-20 package and reel packaging configuration as listed in official Texas Instruments documentation. Confirm that the Q1 designation aligns with required automotive reliability standards for your specific application environment. Ensure compatibility with your board's thermal management capabilities given the specified operating temperature range.

Selection Notes

Select this component when eight bidirectional channels are required for voltage translation in space-constrained automotive designs. The VSSOP-20 package offers a compact footprint suitable for dense PCB layouts. Consider the 110 Mb/s data rate capability to ensure it meets the speed requirements of your target bus protocols. Verify that the 1.4 V minimum supply voltage aligns with your system's power rails.

Part Context

This part belongs to the TXS0108E series of voltage-level translators from Texas Instruments. The series is designed for high-speed bidirectional translation between two voltage domains. The TXS0108 variant specifically provides eight channels, making it suitable for parallel data buses or multiple communication lines. The automotive grade ensures reliability under harsh environmental conditions typical in vehicle electronics.

Replacement Considerations

Check for other variants within the TXS0108 family that may offer different package options such as TSSOP or VQFN if pin compatibility is not strictly limited to VSSOP-20. Ensure any substitute maintains the same AEC-Q100 qualification and channel count for direct functional equivalence.
