Product details
Overview
74AVC4T245D-Q100 from Nexperia is a 4-bit dual-supply translating transceiver enabling bidirectional level translation between independent voltage domains (VCC(A) and VCC(B), each 0.8 V to 3.6 V). It functions as two configurable 2-bit transceivers or one 4-bit unit, with direction control (nDIR), output enable (nOE), and IOFF partial power-down support. Used in automotive infotainment domain controllers interfacing 1.2 V FPGA logic with 3.3 V CAN transceivers.
For engineers reviewing the 74AVC4T245D-Q100 datasheet, 74AVC4T245D-Q100 pinout, 74AVC4T245D-Q100 application, or 74AVC4T245D-Q100 equivalent, key selection criteria include asymmetric supply tolerance, suspend-mode isolation at GND-powered rails, JEDEC-compliant voltage translation across six standard logic families, and AEC-Q100 Grade 1 qualification for under-hood operation.
Technical Context
This device implements dual-rail I/O architecture with separate VCC(A) and VCC(B) supplies, where nAn/nDIR/nOE inputs reference VCC(A), and nBn ports reference VCC(B). Direction control is synchronous: HIGH on nDIR enables A→B data flow; LOW enables B→A.
IOFF circuitry actively disables outputs during partial power-down (e.g., VCC(A) = 0 V, VCC(B) = 3.3 V), limiting backflow current to ±5 μA per port. In suspend mode (either supply at GND), all I/O pins enter high-impedance OFF-state regardless of control input states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply range | VCC(A): 0.8 V–3.6 V; VCC(B): 0.8 V–3.6 V - supports translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic nodes |
| Max data rate | 380 Mbit/s (≥1.8 V ↔ 3.3 V) - enables high-speed inter-domain communication in ADAS sensor fusion modules |
| Propagation delay | Min 0.1 ns / Max 14.7 ns (−40 °C to +125 °C) - ensures timing predictability across full automotive temperature range |
| IOFF leakage | ±5 μA per port at VCC = 0 V - prevents bus contention and latch-up during system sleep/wake transitions |
| ESD rating | HBM >8 kV, CDM >1 kV - meets stringent automotive board-level ESD immunity requirements |
| Operating temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine control and transmission ECUs |
Pinout & Package
SO16 plastic small outline package (SOT109-1), 3.9 mm body width, 16-pin configuration with gull-wing leads. Pin 1 index located at top-left corner; Pin 8 and Pin 9 are GND (both must be connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply rail for A-side I/O and control inputs (nAn, nDIR, nOE); sets VIH/VIL thresholds for those signals |
| 2, 3 | 1DIR, 2DIR | Direction control inputs - HIGH enables A→B; LOW enables B→A; referenced to VCC(A) |
| 4, 5, 6, 7 | 1A1, 1A2, 2A1, 2A2 | A-side bidirectional data terminals - connect to low-voltage domain (e.g., 1.2 V microcontroller I/O) |
| 8, 9 | GND | Common ground reference - both pins must be soldered to PCB ground plane for thermal and noise integrity |
| 10, 11, 12, 13 | 2B2, 2B1, 1B2, 1B1 | B-side bidirectional data terminals - connect to higher-voltage domain (e.g., 3.3 V sensor interface) |
| 14, 15 | 2OE, 1OE | Active-LOW output enable - drives all associated ports into high-Z when HIGH; referenced to VCC(A) |
| 16 | VCC(B) | Supply rail for B-side I/O - sets output drive strength and input thresholds for nBn pins |
Key Features
| Feature | Design Value |
|---|---|
| Configurable 2×2 or 1×4 topology | Two independent DIR/OE pairs allow flexible partitioning - e.g., isolate camera link (A→B) while enabling debug UART (B→A) |
| Asymmetric voltage translation | Supports simultaneous 1.2 V ↔ 3.3 V and 1.8 V ↔ 2.5 V translation on same device - eliminates need for multiple discrete translators |
| Suspend-mode isolation | Automatic high-Z on all I/O when either VCC(A) or VCC(B) = 0 V - critical for safe power sequencing in multi-rail automotive systems |
| JEDEC compliance | Validated per JESD8-12 through JESD8-B - guarantees interoperability with industry-standard logic families without external biasing |
| Side-wettable flanks (SO16) | Enables automated optical inspection (AOI) of solder joints - improves manufacturing yield in automotive PCB assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply translating transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC4T245QPWRQ1 | TI variant with identical pinout and specs but different thermal pad layout (exposed pad vs. SO16 solid bottom); slightly higher ICC at 3.3 V/3.3 V (20 μA vs. 16 μA) | Preferred for thermally constrained layouts requiring enhanced heat dissipation via exposed pad | Select if PCB design includes thermal vias under package; verify solder mask clearance for TI's QFN-style pad |
| 74LVC4T245PW-Q100 | Nexperia LVC variant - narrower supply range (1.65 V–3.6 V), no 0.8 V/1.2 V support; lower max speed (240 Mbit/s) | Suitable only for 1.8 V/2.5 V/3.3 V-only systems; lacks IOFF and suspend-mode behavior | Choose only when cost sensitivity outweighs need for ultra-low-voltage compatibility and robust power sequencing |

FAQ
Can 74AVC4T245D-Q100 translate between 0.8 V and 3.6 V simultaneously?
Yes. VCC(A) and VCC(B) operate independently: set VCC(A) = 0.8 V for 0.8 V logic domain and VCC(B) = 3.6 V for 3.3 V domain. The device maintains valid VIH/VIL thresholds and output drive strength across this full range, validated per JESD8-12 and JESD8-B standards.
What happens when only VCC(A) is powered and VCC(B) = 0 V?
The device enters suspend mode: all nBn pins go high-impedance regardless of nDIR/nOE states, and nAn pins remain functional but isolated from B-side. IOFF limits leakage to ±5 μA, preventing backfeed into the unpowered 3.3 V domain - critical for safe power sequencing in automotive gateways.
Is the SO16 package (SOT109-1) compatible with lead-free reflow profiles?
Yes. The 74AVC4T245D-Q100 in SO16 meets JEDEC J-STD-020D moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C. Its side-wettable flanks enable reliable AOI verification of solder joint quality after lead-free assembly.
How does propagation delay vary with supply asymmetry?
Delay is supply-dependent and directional: A→B delay is dominated by VCC(A) and load on B-side; B→A delay depends on VCC(B) and A-side load. At VCC(A) = 1.2 V / VCC(B) = 3.3 V, typical tpd is 6.2 ns (A→B) and 9.0 ns (B→A), per Table 13 - design must account for this asymmetry in timing-critical paths.
