74LVC2T45GS,115

Translators, Level Shifters Overview

The Nexperia 74LVC2T45GS,115 is a dual-bit translating transceiver with three-state outputs designed for bidirectional level translation. It features two 2-bit input-output ports (nA and nB), a direction control input (DIR), and dual 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. Pins nA and DIR reference VCC(A), while nB references VCC(B). The device supports partial power-down applications via IOFF circuitry and operates within an ambient temperature range of -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Supports bidirectional data transmission between independent voltage domains using a single direction control pin.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow currents during partial power-down states.
• Features high noise immunity and robust latch-up performance exceeding 100 mA per JESD 78 Class II standards.

Translators, Level Shifters Applications

• Partial power-down mode operation
• Bidirectional level translation between mixed voltage logic nodes
• Systems requiring isolated power domains with shared data lines

Translators, Level Shifters Procurement Notes

Verify the specific package designation GS corresponds to SOT1203 (XSON8, 1.35x1 mm) when sourcing. Confirm the suffix ,115 matches the required reel or cut tape packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number 935292804115 if utilizing alternative distributor catalogs.

Translators, Level Shifters Selection Notes

Select this component when designing circuits that require translation between widely varying supply voltages on separate ports. The dual-supply architecture allows independent power management for connected subsystems. Verify that the required propagation delay characteristics align with the target system clock speeds across the intended operating temperature range.
