Product details
Overview
74AVC1T45GM-Q100 from Nexperia is a single-bit, dual-supply voltage level translator/transceiver with 3-state output, enabling bidirectional logic-level translation between 0.8 V and 3.6 V domains (e.g., 1.2 V ↔ 3.3 V). It features independent VCC(A) and VCC(B) supplies, DIR-controlled direction, IOFF partial power-down, and AEC-Q100 Grade 1 qualification for automotive use.
For engineers reviewing the 74AVC1T45GM-Q100 datasheet, 74AVC1T45GM-Q100 pinout, 74AVC1T45GM-Q100 application, or 74AVC1T45GM-Q100 equivalent, key selection criteria include bidirectional translation capability, IOFF-enabled suspend mode, 0.8–3.6 V dual-rail flexibility, and automotive-grade thermal (-40 °C to +125 °C) and ESD (HBM >8 kV) performance.
Technical Context
The device implements a direction-controlled, dual-rail CMOS transceiver architecture where DIR selects signal flow between port A (VCC(A)-referenced) and port B (VCC(B)-referenced). Its IOFF circuit actively disables outputs during power-down, blocking backflow current when either supply is at GND.
Propagation delay (tpd) ranges from 0.5 ns to 9.9 ns depending on supply pair and temperature; enable time (ten) is derived as tdis + tpd per direction, supporting deterministic timing in bidirectional bus systems without external OE control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V per rail - enables translation across all common low-voltage nodes (0.8/1.2/1.5/1.8/2.5/3.3 V) |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood automotive applications per AEC-Q100 Grade 1 |
| Max Data Rate | 500 Mbit/s (1.8 V → 3.3 V) - supports high-speed inter-domain communication in ADAS and infotainment |
| IOFF Leakage | ±1 μA max (VCC = 0 V) - prevents damaging back-current during partial power-down |
| ESD Robustness | HBM >8000 V, CDM >1000 V - ensures reliability in manufacturing and field deployment |
| Propagation Delay | 0.5–9.9 ns (A↔B, -40 °C to +125 °C) - enables sub-10 ns timing-critical level shifting |
| Input Thresholds | VIL = 0.3×VCCI, VIH = 0.65–0.7×VCCI - ensures noise-immune switching across supply combinations |
Pinout & Package
XSON6 package (SOT886): plastic extremely thin small outline, no leads, 6 terminals, body size 1.0 × 1.45 × 0.5 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for port A and DIR input - defines logic thresholds for A and DIR pins |
| 2 | GND | Common reference ground - must be connected before any supply per power-up sequence |
| 3 | A | Bidirectional I/O port referenced to VCC(A) - functions as input or output based on DIR state |
| 4 | B | Bidirectional I/O port referenced to VCC(B) - isolated from A rail; tolerates up to 3.6 V regardless of VCC(B) |
| 5 | DIR | Direction control input (VCC(A)-referenced) - HIGH enables A→B, LOW enables B→A |
| 6 | VCC(B) | Supply for port B - independently set from VCC(A), enabling asymmetric voltage translation |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail translation | Independent 0.8–3.6 V supplies on A and B ports - eliminates need for external level-shifting components |
| IOFF partial power-down | Outputs enter high-Z when either VCC is at GND - prevents backfeed and enables hot-swap capability |
| AEC-Q100 Grade 1 | Qualified from -40 °C to +125 °C - meets automotive reliability requirements for engine control and body electronics |
| Low dynamic power | CPD = 1–17 pF (supply-dependent) - minimizes switching power in battery-sensitive applications |
| Bus contention mitigation | No dedicated OE pin but DIR sequencing support (Table 17) - enables controlled bidirectional operation with external protocol coordination |
Applications
| Automotive Body Control Module (BCM) | ADAS Camera Interface |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC1T45DBVR | Commercial grade (-40 °C to +85 °C); no AEC-Q100 qualification; same pinout and electrical specs | Not suitable for under-hood or safety-critical automotive zones | Select only for non-automotive industrial or consumer designs requiring identical functionality at lower cost |
| TXS0101DCKR | Auto-direction sensing (no DIR pin); higher ICC (20 μA typical); 5-V tolerant inputs | Lacks explicit direction control - relies on data-driven bus arbitration | Prefer when system lacks dedicated DIR signaling and requires passive direction detection |
Compared with SN74AVC1T45DBVR, the 74AVC1T45GM-Q100 adds AEC-Q100 Grade 1 qualification and extended +125 °C operation; versus TXS0101DCKR, it provides deterministic DIR-controlled timing and lower static current, critical for safety-critical automotive timing paths.

FAQ
What is the minimum valid voltage difference between VCC(A) and VCC(B)?
No minimum voltage difference is required: VCC(A) and VCC(B) may be equal (e.g., both 1.8 V) or differ by as little as 0.1 V. The device operates correctly across the full 0.8 V–3.6 V range on each rail independently, with no inter-rail dependency beyond functional translation.
Can DIR be driven from a different voltage domain than VCC(A)?
No - DIR is strictly referenced to VCC(A), and its input thresholds (VIH/VIL) scale with VCC(A). Driving DIR from another supply violates the absolute maximum ratings and risks undefined behavior or damage. A level shifter must be used if DIR originates from a non-VCC(A) domain.
How does suspend mode behave when only VCC(A) is powered?
When VCC(A) = nominal voltage and VCC(B) = GND, the B port enters high-impedance OFF-state (Z), while A port remains functional. This allows safe isolation of the B-side bus during partial system power-down, preventing contention or leakage into unpowered circuitry.
Is external pull-up/pull-down required on A or B ports?
Not required for basic operation, but recommended on shared buses to prevent floating states during DIR transitions. The device has no internal bus-hold or weak pull resistors; external termination ensures deterministic logic levels during 3-state intervals and avoids metastability in bidirectional protocols.
