74LVC2T45GS-Q100X

Translators, Level Shifters Overview

The Nexperia 74LVC2T45GS-Q100X is a dual-bit, dual-supply translating transceiver with 3-state outputs designed for bidirectional level translation. It features two 2-bit input-output ports (nA and nB), a direction control input (DIR), and independent supply pins VCC(A) and VCC(B). Both supplies support voltages from 1.2 V to 5.5 V, enabling translation between low voltage nodes including 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device includes IOFF circuitry for partial power-down applications and active bus hold functionality.

Translators, Level Shifters Feature Summary

• Supports bidirectional data transmission between independent voltage domains ranging from 1.2 V to 5.5 V
• Includes IOFF circuitry to disable outputs and prevent backflow current during partial power-down states
• Features active bus hold circuitry to maintain valid logic levels on unused or floating inputs
• Complies with AEC-Q100 Grade 1 qualification standards for automotive reliability

Translators, Level Shifters Applications

• Automotive electronic systems requiring robust voltage translation
• Mixed-voltage digital interfaces connecting different logic families
• Partial power-down scenarios in battery-operated devices
• Bidirectional data buses operating across varying supply rails

Translators, Level Shifters Procurement Notes

Verify the specific suffix GS indicates the XSON8 package (SOT1203) configuration when ordering. Confirm that the Q100 designation aligns with required automotive grade specifications. Ensure compatibility with the target application's voltage requirements before procurement. Check for any recent product change notifications regarding marking codes or packaging updates.

Translators, Level Shifters Selection Notes

Select this component when designing circuits requiring bidirectional translation between two distinct voltage domains within the 1.2 V to 5.5 V range. It is suitable for applications needing controlled directionality via the DIR pin and high-impedance states. Consider the XSON8 package dimensions if space constraints are critical. Verify that the required propagation delay characteristics meet the system timing specifications under the intended operating temperatures.

Translators, Level Shifters Part Context

This part belongs to the 74LVC/LVCH2T45-Q100 family of dual supply translating transceivers manufactured by Nexperia. It shares functional similarities with other members like the 74LVCH2T45-Q100 but differs in specific electrical characteristics such as bus hold capabilities. The family is designed for automotive and industrial applications requiring reliable voltage level shifting.

Translators, Level Shifters Replacement Considerations

The 74LVCH2T45GS-Q100X serves as a direct functional substitute within the same package and qualification standard. Verify that the bus hold features of the LVCH variant are acceptable for the specific design requirements.
