Product details
Overview
74AVC1T45GS-Q100 from Nexperia is a single-bit, dual-supply bidirectional voltage level translator/transceiver with 3-state output, designed for automotive-grade inter-system communication between mismatched logic domains (e.g., 1.2 V MCU ↔ 3.3 V sensor interface). It supports independent VCC(A) and VCC(B) supplies from 0.8 V to 3.6 V, enables direction control via DIR pin, features IOFF circuitry for partial power-down, and operates across −40 °C to +125 °C.
For engineers reviewing the 74AVC1T45GS-Q100 datasheet, 74AVC1T45GS-Q100 pinout, 74AVC1T45GS-Q100 application, or 74AVC1T45GS-Q100 equivalent, key selection criteria include bidirectional translation latency (as low as 2.4 ns at 3.3 V), suspend-mode high-impedance behavior during supply loss, AEC-Q100 Grade 1 qualification, and compatibility with JEDEC standards JESD8-12 through JESD8C.
Technical Context
The device implements a CMOS-based dual-rail transceiver architecture where A port is referenced to VCC(A) and B port to VCC(B), with DIR input tied to VCC(A). Directional data flow is controlled dynamically: DIR = HIGH enables A→B translation; DIR = LOW enables B→A translation. No external pull-ups are required for bus contention avoidance in bidirectional mode when managed per Table 17 timing sequence.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) drops to GND, preventing backflow current and ensuring safe partial power-down. Suspend mode places both A and B ports in high-impedance OFF-state regardless of DIR state, supporting hot-swap and power-gating use cases in automotive domain controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V per rail - enables translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level-shifter ICs. |
| Max Data Rate | 500 Mbit/s (1.8 V → 3.3 V) - supports high-speed serial links like I²C fast-mode plus or GPIO-controlled sensor interfaces. |
| Propagation Delay | 2.4 ns min (VCC(A)=3.3 V, VCC(B)=3.3 V) - ensures sub-nanosecond timing margin for real-time automotive control loops. |
| IOFF Leakage | ±1 μA max (VCC=0 V) - guarantees <100 nW standby power in powered-down subsystems, critical for battery-sensitive modules. |
| ESD Rating | HBM >8 kV, CDM >1 kV - meets automotive system-level ESD robustness requirements per ISO 10605. |
| Operating Temp | −40 °C to +125 °C - qualified for engine bay, ADAS camera, and infotainment head-unit environments. |
| AEC-Q100 Grade | Grade 1 - certified for automotive applications requiring reliability under extended temperature and lifetime stress conditions. |
Pinout & Package
XSON6 package (SOT1202): extremely thin small outline, no leads, 6-terminal surface-mount, body size 1.0 × 1.0 × 0.35 mm, thermal pad optional, pin 1 index located at lower-left corner below marking code "B5".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC(A) | Supply rail for A port and DIR input | Defines logic thresholds for DIR and A I/O; must be stable before signal assertion. |
| 2 GND | Reference ground | Common return path for both rails; requires low-inductance connection to minimize noise coupling. |
| 3 A | Bidirectional data I/O referenced to VCC(A) | Connects to low-voltage domain (e.g., 1.2 V MCU GPIO); supports dynamic drive strength scaling. |
| 4 B | Bidirectional data I/O referenced to VCC(B) | Connects to higher-voltage domain (e.g., 3.3 V CAN transceiver sideband line); tolerant to 3.6 V inputs. |
| 5 DIR | Direction control input | Active-HIGH for A→B, active-LOW for B→A; referenced to VCC(A); no internal pull-up/down. |
| 6 VCC(B) | Supply rail for B port | Independent of VCC(A); enables true dual-voltage operation without shared regulator constraints. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail translation | Enables seamless interoperability between heterogeneous SoCs, MCUs, and peripherals operating at different core voltages. |
| IOFF partial power-down | Prevents damaging back-current when one domain powers down while the other remains active - essential for modular vehicle E/E architectures. |
| Suspend-mode high-Z | Guarantees bus isolation during cold-start or domain reset sequences, eliminating need for external isolation switches. |
| JEDEC-compliant voltage ranges | Validated against JESD8-12 (0.8–1.3 V), JESD8-11 (0.9–1.65 V), JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), and JESD8C (2.7–3.6 V). |
| Low dynamic power dissipation | CPD = 2 pF (A→B) / 17 pF (B→A) at 3.3 V - reduces switching noise and thermal load in dense PCB layouts. |
Applications
| Automotive Body Control Module (BCM) | ADAS Camera Interface |

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 |
|---|---|---|---|
| SN74AVC1T45QDRYRQ1 | TI part; same pinout (X2SON-6), identical VCC range (0.8–3.6 V), but rated only to +105 °C (not Grade 1). | Lacks AEC-Q100 Grade 1 qualification; unsuitable for under-hood or safety-critical EPS/brake modules. | Select only for non-automotive industrial or consumer applications where extended temperature is not required. |
| TXS0101QPWRQ1 | TI auto-grade part (AEC-Q100 Grade 1); uses auto-direction sensing (no DIR pin); max data rate 60 Mbit/s. | Lower speed ceiling limits use in high-bandwidth sensor links; direction detection adds ~10 ns latency vs. explicit DIR control. | Prefer when board space is constrained and direction changes infrequently; avoid for real-time bidirectional protocols like SPI or custom GPIO handshakes. |
Compared with SN74AVC1T45QDRYRQ1 and TXS0101QPWRQ1, the 74AVC1T45GS-Q100 uniquely delivers Grade 1 qualification *plus* 500 Mbit/s performance *plus* deterministic DIR control - making it the only option for high-speed, safety-relevant automotive domain bridging.

FAQ
What is the minimum recommended VCC differential between VCC(A) and VCC(B)?
No minimum differential is specified - the device supports identical or disparate rail voltages (e.g., 1.2 V/1.2 V or 1.2 V/3.3 V). Both supplies must independently meet 0.8 V to 3.6 V, and GND must be common. Operation is guaranteed across all valid combinations per Tables 6 and 7.
Can the DIR pin be left floating in a unidirectional application?
No - DIR must be actively driven HIGH or LOW. Floating DIR causes undefined direction behavior and potential bus contention. For unidirectional use, tie DIR to VCC(A) (for A→B) or GND (for B→A) via a 10 kΩ resistor; no pull-up/down is internal.
Does the 74AVC1T45GS-Q100 support hot insertion when one supply is ramping?
Yes - the IOFF circuitry activates automatically when either VCC(A) or VCC(B) falls below ~0.2 V, forcing outputs into high-impedance state before supply collapse. This prevents back-driving and latch-up during hot-swap events in modular automotive ECUs.
How does suspend mode behave if only VCC(A) is powered and VCC(B) = 0 V?
Both A and B ports enter high-impedance OFF-state regardless of DIR state or input levels. The A port remains input-capable (VI allowed up to 3.6 V), but no output is sourced - ensuring safe isolation of the unpowered B-domain bus.
