Overview
The Nexperia 74AVCH2T45GS,115 is a dual-bit, dual-supply voltage level translator and transceiver housed in an XSON8 package (SOT1203). It supports bidirectional data translation between ports A and B with independent supply voltages ranging from 0.8 V to 3.6 V. The device features a direction control input (DIR) for transmission routing, IOFF circuitry for partial power-down protection, and active bus hold on data inputs. It operates within a temperature range of -40 °C to +125 °C.
Feature Summary
- Bidirectional level translation between two independent low-voltage domains
- IOFF circuitry prevents damaging backflow current during partial power-down
- Active bus hold maintains valid logic levels on floating or unused inputs
Applications
- Bidirectional logic level-shifting between systems operating at different voltage nodes
- Partial power-down applications requiring isolation of powered-off ports
- Interfacing low-voltage microcontrollers with peripherals at varying supply levels
Procurement Notes
Verify the specific ordering suffix
Selection Notes
Select this component when bidirectional translation between two distinct voltage domains is required. Ensure both VCC(A) and VCC(B) fall within the 0.8 V to 3.6 V range. Confirm that the XSON8 package dimensions meet board space constraints. Verify DIR pin referencing to VCC(A) aligns with system control logic.
Part Context
This part belongs to the 74AVCH series of high-speed CMOS logic devices manufactured by Nexperia. It is specifically designed as a dual-bit translator, contrasting with octal variants like the 74LVT2245 which include termination resistors. The GS suffix denotes the XSON8 package variant, distinguishing it from VSSOP or other XSON versions within the same logical family.
Replacement Considerations
Direct substitutes within the same package include 74AVCH2T45GT and 74AVCH2T45GN. For alternative packages, consider 74AVCH2T45DC (VSSOP8). Verify electrical characteristics and thermal performance match before substitution.
