74LVCH2T45GS,115

Translators, Level Shifters Overview

The Nexperia 74LVCH2T45GS,115 is a dual-bit, dual-supply translating transceiver with 3-state outputs. It enables bidirectional level translation between ports A and B using separate supply pins VCC(A) and VCC(B), both supporting voltages from 1.2 V to 5.5 V. The device features a direction control input (DIR) for data flow management and IOFF circuitry for partial power-down applications. It includes active bus hold circuitry to maintain valid logic levels on unused inputs. Packaged in an XSON8 (SOT1203) format, it operates across -40 °C to +125 °C.

Translators, Level Shifters Feature Summary

• Bidirectional voltage level translation between independent dual supplies
• Active bus hold circuitry prevents floating inputs
• IOFF circuitry disables outputs during power-down
• High noise immunity with overvoltage tolerant inputs

Translators, Level Shifters Applications

• Mixed voltage system interconnects
• Portable equipment communication interfaces
• Consumer electronics signal translation

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package variant. Confirm that the GS designation corresponds to the SOT1203 XSON8 footprint dimensions. Ensure compatibility with the target PCB layout before finalizing procurement orders.

Translators, Level Shifters Selection Notes

Select this component when interfacing circuits operating at different voltage nodes within the 1.2 V to 5.5 V range. The LVCH series provides active bus hold functionality, eliminating the need for external pull-up resistors. Verify that the application requires dual-supply architecture rather than single-supply translation.

Translators, Level Shifters Part Context

This part belongs to the Nexperia LVC/LVCH logic family, designed for low-voltage CMOS applications. It serves as a compact solution for bi-directional data transfer in space-constrained designs. The device integrates standard logic functions with specialized level-shifting capabilities for mixed-signal environments.

Translators, Level Shifters Replacement Considerations

The 74LVC2T45GS,115 is functionally similar but lacks active bus hold circuitry. Verify if external pull-up resistors are acceptable if substituting with the non-H variant.
