Overview
The Nexperia 74AVC2T45GS,115 is a dual-bit, dual-supply voltage level translator and transceiver housed in an XSON8 package (SOT1203). It supports bidirectional data translation between two independent power domains, VCC(A) and VCC(B), both ranging from 0.8 V to 3.6 V. The device features a direction control input (DIR) to manage transmission flow. Key electrical parameters include a maximum propagation delay of 11.8 ns at 3.3 V, operating temperatures from -40 °C to +125 °C, and ESD protection exceeding 8000 V (HBM) and 1000 V (CDM).
Feature Summary
- Enables bidirectional level translation between any low-voltage nodes within the 0.8 V to 3.6 V range.
- Includes IOFF circuitry for partial power-down applications to prevent damaging backflow currents.
- Features high noise immunity with low overshoot and undershoot specifications.
- Complies with multiple JEDEC standards covering supply voltages from 0.8 V to 3.6 V.
Applications
- Translating signals between mixed voltage systems such as 1.8 V and 3.3 V.
- Connecting memory interfaces requiring different supply rails.
- Bidirectional bus interfacing in embedded systems with varying logic levels.
Procurement Notes
Verify the ordering suffix '115' corresponds to the XSON8 (SOT1203) package variant. Confirm the temperature grade is specified for -40 °C to +125 °C operation. Ensure the datasheet revision matches current design requirements. Check for specific marking codes if visual inspection is required during assembly.
Selection Notes
Select this component when designing circuits that require bidirectional translation between two distinct voltage domains within the 0.8 V to 3.6 V range. It is suitable for applications needing explicit direction control via the DIR pin rather than auto-direction sensing. Consider the XSON8 package for space-constrained PCB layouts requiring leadless terminals.
Part Context
This part belongs to the 74AVC series of advanced CMOS logic devices. It is specifically designed as a dual-transceiver for voltage level shifting. The GS suffix indicates the XSON8 package type, distinguishing it from other variants like DC (VSSOP8) or DP (TSSOP8) which share similar electrical characteristics but differ in physical footprint.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official Nexperia resources for cross-reference information.
