Product details
Overview
74AVC2T45DC-Q100 from Nexperia is a dual-bit, dual-supply voltage level translator/transceiver enabling bidirectional logic-level translation between 0.8 V and 3.6 V domains. It features independent VCC(A) and VCC(B) supplies, DIR-controlled data direction (A↔B), 3-state outputs, and IOFF circuitry for partial power-down. Used in automotive infotainment and ADAS domain controllers interfacing mixed-voltage SoCs and peripherals.
For engineers reviewing the 74AVC2T45DC-Q100 datasheet, 74AVC2T45DC-Q100 pinout, 74AVC2T45DC-Q100 application, or 74AVC2T45DC-Q100 equivalent, key selection criteria include bidirectional translation capability across 0.8–3.6 V rails, AEC-Q100 Grade 1 qualification, Suspend mode behavior during rail collapse, and propagation delay ≤9.2 ns at 3.3 V translation.
Technical Context
The device implements a dual-channel, direction-controlled bus transceiver with separate supply references: pins 1A, 2A, and DIR are referenced to VCC(A); pins 1B and 2B to VCC(B). Direction control is synchronous-DIR HIGH enables A→B transmission; DIR LOW enables B→A transmission. No internal OE pin exists, requiring external bus arbitration in bidirectional systems.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing both ports into high-impedance OFF-state. IOFF circuitry ensures sub-μA leakage (<±35 μA max at +125 °C) during partial power-down, preventing damaging backflow current. Input thresholds scale with respective VCC rails per JEDEC standards JESD8-12 through JESD8-B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A): 0.8 V to 3.6 V; VCC(B): 0.8 V to 3.6 V - supports translation between any low-voltage node (0.8/1.2/1.5/1.8/2.5/3.3 V) |
| Max Data Rate | 500 Mbit/s - achievable when translating between 1.8 V and 3.3 V rails |
| Propagation Delay | ≤9.2 ns (A→B @ VCC(A)=3.3 V, VCC(B)=3.3 V) - ensures timing closure in high-speed inter-domain links |
| IOFF Leakage | ≤±35 μA @ +125 °C - guarantees safe partial power-down without backfeed current in automotive subsystems |
| ESD Protection | HBM >8000 V, CDM >1000 V - meets stringent automotive board-level ESD robustness requirements |
| Operating Temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin electronics |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8 leads, body width 2.3 mm, lead pitch 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for A-side I/O and DIR input - sets voltage reference for 1A, 2A, and DIR thresholds |
| 2 | 1A | Data I/O port A channel 1 - bidirectional signal referenced to VCC(A) |
| 3 | 2A | Data I/O port A channel 2 - bidirectional signal referenced to VCC(A) |
| 4 | GND | Common ground reference - must be connected before VCC rails per power-up requirement |
| 5 | DIR | Direction control input - HIGH enables 1A↔1B / 2A↔2B; referenced to VCC(A) |
| 6 | 2B | Data I/O port B channel 2 - bidirectional signal referenced to VCC(B) |
| 7 | 1B | Data I/O port B channel 1 - bidirectional signal referenced to VCC(B) |
| 8 | VCC(B) | Supply for B-side I/O - sets voltage reference for 1B and 2B thresholds |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional Translation | Single DIR pin controls two independent data paths (1A↔1B, 2A↔2B) without external logic |
| IOFF Partial Power-down | Enables safe isolation of powered-down domains while other rail remains active - critical for domain sleep/wake sequencing |
| Suspend Mode | Automatic high-Z on both ports if either VCC(A) or VCC(B) collapses to GND - prevents bus contention during rail faults |
| AEC-Q100 Grade 1 | Qualified for automotive use from −40 °C to +125 °C ambient - validated for engine control, ADAS, and infotainment |
| JEDEC Compliance | Meets JESD8-12 through JESD8-B across 0.8–3.6 V - ensures interoperability with industry-standard logic families |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply voltage level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC2T45RSVR | Non-automotive grade; rated −40 °C to +85 °C only; identical pinout and electrical specs | Lacks AEC-Q100 qualification and extended temperature support - unsuitable for under-hood or safety-critical modules | Select only for non-automotive industrial or consumer designs where cost sensitivity outweighs qualification needs |
| TXS0102DCUR | Auto-direction sensing (no DIR pin); higher typical propagation delay (14 ns); lower max data rate (24 Mbps) | Eliminates direction control logic but cannot guarantee contention-free operation in deterministic bidirectional protocols like SPI | Prefer for simple GPIO translation; avoid where precise DIR-timed handshaking or high-speed serial is required |
Compared with SN74AVC2T45RSVR and TXS0102DCUR, the 74AVC2T45DC-Q100 uniquely delivers AEC-Q100 Grade 1 compliance, 500 Mbit/s capability, and deterministic DIR-controlled timing - making it the sole choice for automotive domain controllers requiring both performance and functional safety assurance.

FAQ
What is the minimum valid VCC(A) and VCC(B) voltage for functional operation?
The device operates across 0.8 V to 3.6 V for both VCC(A) and VCC(B), with guaranteed functionality down to 0.8 V. Below 0.8 V, input thresholds and output drive strength degrade; operation below −0.5 V absolute maximum rating risks permanent damage. The 0.8 V lower limit is validated per JEDEC JESD8-12 and confirmed in static characteristics tables.
How does Suspend mode behave when only VCC(B) is powered?
When VCC(B) = GND and VCC(A) is powered, both 1B and 2B ports enter high-impedance OFF-state immediately, while 1A and 2A remain functional but isolated from B-side. DIR retains its VCC(A)-referenced logic state. This prevents backdrive from A-side into unpowered B-rail - a critical feature for domain power sequencing in automotive gateways.
Can the 74AVC2T45DC-Q100 translate between 3.3 V and 5 V logic levels?
No. Absolute maximum ratings cap VCC(A) and VCC(B) at +4.6 V, but recommended operation is strictly 0.8 V to 3.6 V. Inputs tolerate up to 3.6 V regardless of supply, but output swing is clamped to the active VCC rail. Driving a true 5 V bus requires a different translator family (e.g., TXB series) or external level-shifting circuitry.
Is there a recommended power-up sequence to avoid latch-up or undefined states?
Yes: GND must be applied first, followed by either or both VCC rails. No specific sequencing between VCC(A) and VCC(B) is required. DIR and I/O pins may float until their respective VCC is stable. This sequence is verified per JESD78 latch-up testing (>100 mA) and documented in Section 12.3 of the datasheet.
