Nexperia USA Inc. 74AVC1T45GM,115

Overview

74AVC1T45GM,115 from Nexperia is a single-bit dual-supply voltage level translator/transceiver with 3-state output, enabling bidirectional logic-level translation between independent 0.8 V–3.6 V domains. It features separate VCC(A) and VCC(B) supplies, DIR-controlled direction (A↔B), IOFF partial power-down protection, and operates across –40 °C to +125 °C. Used in mixed-voltage SoC interfaces, FPGA I/O bridging, and low-power sensor hubs.

For engineers reviewing the 74AVC1T45GM,115 datasheet, 74AVC1T45GM,115 pinout, 74AVC1T45GM,115 application, or 74AVC1T45GM,115 equivalent, key selection criteria include dual-rail supply flexibility, sub-10 ns propagation delay at 1.8 V/3.3 V, IOFF-enabled suspend mode, ±1 μA max input leakage at 125 °C, and XSON6 (SOT886) package compatibility with high-density PCB layouts.

Technical Context

The device implements a CMOS-based bidirectional transceiver architecture with direction control referenced solely to VCC(A). Its IOFF circuit actively disables outputs when either VCC(A) or VCC(B) is at GND, preventing backflow current and ensuring bus isolation during partial power-down.

Propagation delay varies with supply pairing: e.g., 7.7 ns (A→B) at VCC(A)=1.8 V / VCC(B)=3.3 V, and 3.4 ns (DIR→B) under same conditions. Enable/disable timing is derived from tdis + tpd combinations per Section 12.4, supporting deterministic bidirectional bus arbitration.

FAQ

What is the minimum valid VCC(A) and VCC(B) voltage for functional operation?

The 74AVC1T45GM,115 is fully specified from 0.8 V to 3.6 V on both VCC(A) and VCC(B) rails. At 0.8 V, it delivers guaranteed VOL ≤ 0.07 V and VOH ≥ 0.69 V with 1.5 mA load, and supports 280 Mbit/s translation to 1.5 V. Operation below 0.8 V is not characterized or recommended.

Can DIR be left floating, or does it require a defined logic level?

DIR must never be left floating. It has no internal pull-up or pull-down; undefined voltage may cause metastability, bus contention, or excessive current draw. External bias (e.g., 10 kΩ to VCC(A) or GND) is mandatory per application requirements - typically pulled HIGH for A→B or LOW for B→A default state.

How does the IOFF feature behave when only VCC(A) is powered?

When VCC(A) = 0 V and VCC(B) = 1.8 V–3.6 V, the IOFF circuit forces both A and B ports into high-impedance OFF-state. Input leakage on B is limited to ±5 μA max, and no back-current flows into the unpowered A port - satisfying IEC 62379-3 partial power-down safety requirements.

Is the XSON6 (SOT886) package compatible with standard reflow profiles?

Yes - the 74AVC1T45GM,115 in SOT886 uses standard SnAgCu (SAC305) reflow profile with peak temperature ≤ 260 °C, T_max = 60 s, and MSL1 rating. The 0.5 mm height and 0.4 mm pitch allow placement on 6-layer HDI PCBs using 6 mil traces and 8 mil vias without thermal shadowing issues.
