Product details
Overview
74AVC1T45GW-Q100 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 (e.g., 1.2 V MCU ↔ 3.3 V sensor interface). It features A/B data ports, DIR control referenced to VCC(A), IOFF partial power-down protection, and AEC-Q100 Grade 1 qualification for automotive use.
For engineers reviewing the 74AVC1T45GW-Q100 datasheet, 74AVC1T45GW-Q100 pinout, 74AVC1T45GW-Q100 application, or 74AVC1T45GW-Q100 equivalent, key selection criteria include dual-rail voltage flexibility, suspend-mode behavior during partial power-down, propagation delay asymmetry (A→B vs B→A), and TSSOP6 package thermal derating above 83 °C.
Technical Context
This device implements a direction-controlled bidirectional bus transceiver without dedicated OE, relying on DIR to gate signal flow between A and B ports. Its IOFF circuit actively disables outputs when either VCC(A) or VCC(B) is at GND, preventing backflow current and ensuring high-impedance OFF-state in suspend mode.
Electrical behavior is supply-voltage-dependent: VIH/VIL thresholds scale with VCC(A) for DIR and with respective VCCI for data ports; propagation delays vary significantly with VCC(A)/VCC(B) combinations-e.g., A→B tpd ranges from 0.5 ns (3.3 V → 3.3 V) to 15.5 ns (0.8 V → 0.8 V); dynamic power dissipation capacitance differs by direction (CPD = 1–2 pF A→B vs 9–17 pF B→A).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply range VCC(A) | 0.8 V to 3.6 V - supports direct interface to 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| Supply range VCC(B) | 0.8 V to 3.6 V - enables independent rail translation, e.g., 1.8 V FPGA ↔ 2.5 V ADC |
| Max data rate | 500 Mbit/s - achievable only for 1.8 V–3.3 V translation; drops to 240 Mbit/s for 1.2 V translation |
| Propagation delay (A→B) | 0.5–15.5 ns - highly dependent on VCC pair; critical for timing budget in high-speed bidirectional buses |
| IOFF leakage (VCC = 0 V) | ±1 μA max - ensures safe isolation during system sleep states without external pull-ups |
| ESD rating (HBM) | >8000 V - exceeds JEDEC JS-001 Class 3B, suitable for automotive assembly environments |
| Operating temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and ADAS applications |
Pinout & Package
TSSOP6 (SOT363-2) package: plastic thin shrink small outline, 6-lead, 1.25 mm body width, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply reference for port A and DIR input; defines VIH/VIL thresholds for DIR |
| 2 | GND | Common ground return for both supply domains; must be low-inductance connection |
| 3 | A | Bidirectional I/O port referenced to VCC(A); functions as input or output depending on DIR state |
| 4 | B | Bidirectional I/O port referenced to VCC(B); voltage-tolerant up to 3.6 V regardless of VCC(B) |
| 5 | DIR | Direction control input (active-HIGH = A→B, active-LOW = B→A); referenced to VCC(A) |
| 6 | VCC(B) | Supply reference for port B; determines VOH/VOL levels and load drive capability on B port |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Independent 0.8–3.6 V rails on A and B ports enable interoperability across mixed-voltage SoC subsystems |
| IOFF partial power-down | Automatic high-Z output disable when either VCC is at GND, eliminating need for external isolation switches |
| Suspend mode operation | Both A and B enter high-impedance state if VCC(A) = 0 V or VCC(B) = 0 V - essential for low-power automotive domain shutdown |
| Asymmetric CPD | 1–2 pF (A→B) vs 9–17 pF (B→A) - informs layout decisions to minimize capacitive loading on critical high-speed paths |
| JEDEC-compliant interfaces | Validated against JESD8-12 through JESD8C standards - guarantees compatibility with industry-standard low-voltage logic families |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC1T45DBVR | Industrial grade (−40 °C to +85 °C), no AEC-Q100 qualification; identical pinout and electrical specs except for temp range and qualification | Not suitable for automotive under-hood or safety-critical modules requiring AEC-Q100 Grade 1 | Select only for non-automotive industrial or consumer designs where extended temperature and qualification are unnecessary |
| TXS0101DCKR | Auto-direction sensing (no DIR pin); higher CPD (12–15 pF); lower max speed (100 Mbit/s); different enable timing model | Eliminates DIR control logic but introduces bus-contention risk during direction transitions; unsuitable for deterministic timing-critical links | Prefer only for simple GPIO translation where direction changes infrequently and timing margins are generous |
Compared with SN74AVC1T45DBVR and TXS0101DCKR, the 74AVC1T45GW-Q100 uniquely delivers AEC-Q100 Grade 1 compliance, asymmetric low-Cpd performance for high-speed A→B paths, and deterministic DIR-controlled timing-making it the sole choice for automotive bidirectional serial interfaces requiring guaranteed timing and reliability.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
The datasheet does not specify a maximum differential voltage limit. Both supplies are independently rated from −0.5 V to +4.6 V, and operation is valid for any combination within their 0.8 V–3.6 V recommended range. However, simultaneous application of 3.3 V on one rail and 0.8 V on the other is fully supported and commonly used in practice.
Can the DIR pin be driven by a 3.3 V signal when VCC(A) = 1.2 V?
No. The DIR input is referenced to VCC(A), so its VIH/VIL thresholds scale with VCC(A). At VCC(A) = 1.2 V, VIH(min) = 0.7 × 1.2 V = 0.84 V; a 3.3 V signal would exceed the absolute maximum input voltage of +4.6 V but more critically violates the recommended VI ≤ VCC(A) + 0.3 V limit, risking latch-up or damage.
How does suspend mode behave when only VCC(B) is powered?
When VCC(B) = 0 V and VCC(A) is active, the B port enters high-impedance OFF-state (Z), while the A port remains functional. However, the function table specifies that the entire device enters suspend mode-and both A and B go to Z-only when *either* VCC(A) *or* VCC(B) is at GND. So yes: with VCC(B) = 0 V and VCC(A) > 0 V, both ports are in high-impedance state.
Is there a minimum pulse width requirement for the DIR signal?
Yes. To ensure reliable direction switching, DIR must remain stable for ≥ tdis (DIR→B or DIR→A) before data is applied. From Table 12, worst-case tdis is 9.7 ns at −40 °C to +125 °C. Therefore, DIR pulse width should exceed 10 ns to guarantee clean disable/enable transitions and avoid metastability or bus contention.
