Product details
Overview
74AVC16T245EV/G,51 from Nexperia is a 16-bit dual-supply translating transceiver with bidirectional level-shifting, 3-state outputs, and independent VCC(A) and VCC(B) rails (0.8 V to 3.6 V). It functions as two independent 8-bit transceivers or one unified 16-bit unit, enabling voltage translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V domains. Used in mixed-voltage SoC interconnects, memory expansion buses, and FPGA I/O bridging where signal integrity and power-aware isolation are critical.
For engineers reviewing the 74AVC16T245EV/G,51 datasheet, 74AVC16T245EV/G,51 pinout, 74AVC16T245EV/G,51 application, or 74AVC16T245EV/G,51 equivalent, key selection criteria include configurable direction control per port pair, IOFF-enabled partial power-down, JEDEC-compliant voltage translation across six logic families, and guaranteed operation from −40 °C to +125 °C.
Technical Context
The device implements two independent 8-bit transceiver blocks (Port A and Port B), each with dedicated nDIR (direction) and nOE (output enable) inputs referenced to VCC(A). Data paths support bidirectional flow: HIGH on nDIR routes nAn → nBn; LOW routes nBn → nAn. All I/O pins tolerate up to 3.6 V regardless of supply voltage.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing all nAn and nBn pins into high-impedance OFF-state. The integrated IOFF circuit disables outputs during power-down, preventing damaging backflow current and meeting JESD78 Class II latch-up robustness (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 0.8 V to 3.6 V - Enables interface to 0.8 V core logic while maintaining compatibility with legacy 1.8 V/3.3 V peripherals. |
| VCC(B) Range | 0.8 V to 3.6 V - Allows asymmetric rail configuration (e.g., VCC(A) = 1.2 V, VCC(B) = 3.3 V) for heterogeneous system integration. |
| Max Data Rate | 380 Mbit/s - Achievable when translating ≥1.8 V to 3.3 V, supporting high-speed DDR memory bus extensions and PCIe sideband signaling. |
| Propagation Delay | 2.7 ns (min) to 16.4 ns (max) - Measured across full temp/voltage range; enables timing-critical inter-chip communication in real-time controllers. |
| IOFF Leakage | ±5 μA max at −40 °C to +125 °C - Ensures safe hot-swap capability and prevents bus contention during partial system power-down. |
| ESD Protection | HBM >8000 V, CDM >1000 V - Meets industrial-grade handling requirements without external protection components. |
| Operating Temp | −40 °C to +125 °C - Qualified for under-hood automotive ECUs, industrial PLC backplanes, and telecom line cards. |
Pinout & Package
TSSOP48 package (SOT362-1), 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm lead pitch. RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH selects nAn→nBn; LOW selects nBn→nAn - Enables dynamic data path reversal without firmware intervention. |
| 1OE, 2OE | Output enable input | Active-LOW enables 3-state output drivers - Allows bus sharing among multiple transceivers on same net. |
| 1A1–1A8, 2A1–2A8 | Port A data I/O | I/O pins referenced to VCC(A); accept 0–3.6 V inputs - Interfaces directly with low-voltage cores without level-shifter buffers. |
| 1B1–1B8, 2B1–2B8 | Port B data I/O | I/O pins referenced to VCC(B); tolerate 0–3.6 V - Supports connection to higher-voltage peripherals (e.g., 3.3 V sensors, 2.5 V memories). |
| VCC(A), VCC(B) | Independent supply rails | Separate power domains isolate noise and enable independent power sequencing - Critical for mixed-signal SoC partitioning. |
| GND (pins 4,10,15,21,28,34,39,45) | Ground reference | Eight dedicated ground pins minimize ground bounce and ensure stable reference for both ports - Required for signal integrity at >200 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable voltage translation | Supports 0.8 V ↔ 1.2 V, 1.5 V ↔ 2.5 V, 1.8 V ↔ 3.3 V, and 12 other combinations - Eliminates need for discrete level shifters in multi-rail systems. |
| IOFF partial power-down | Outputs disable automatically when either VCC rail drops to GND - Prevents back-driving and enables safe hot-plug of daughterboards or modules. |
| Dual 8-bit port architecture | Two independent nDIR/nOE pairs allow simultaneous bidirectional transfers across separate data channels - Optimizes bandwidth in memory-mapped I/O and dual-bus arbitration. |

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 |
|---|---|---|---|
| SN74AVC16T245DGGR | TI part in same TSSOP48 package; identical pinout but different IOFF threshold (VCC < 0.25 V vs. Nexperia's GND-level detection) and slightly higher ICC at 3.3 V. | Valid for commercial-temp (−40 °C to +85 °C) designs only; not qualified for extended temperature automotive or industrial use. | Select when cost sensitivity outweighs extended temp qualification and IOFF precision. |
| 74LVC16T245PW,118 | Nexperia LVC variant; single 1.65–3.6 V supply, no VCC(B) rail - lacks true dual-supply translation capability below 1.65 V. | Only supports 1.8 V ↔ 3.3 V and 2.5 V ↔ 3.3 V translation; cannot interface 0.8 V/1.2 V logic domains. | Choose only if system uses uniform ≥1.65 V supplies and does not require sub-1.65 V interoperability. |

FAQ
What is the minimum operating voltage for VCC(A) and VCC(B) simultaneously?
The device operates with both VCC(A) and VCC(B) as low as 0.8 V concurrently. This enables full functionality in ultra-low-power subsystems such as battery-backed real-time clocks or sensor hubs where core logic runs at 0.8 V and peripherals at 1.2 V. No derating or reduced performance occurs at this minimum.
How does the IOFF feature behave when only VCC(A) is powered?
When VCC(A) is active and VCC(B) = GND, the IOFF circuit forces all Port B (nBn) pins into high-impedance state while Port A remains functional. This allows safe isolation of the B-side bus without disrupting A-side communication - essential for hot-swap I/O modules and modular compute blades.
Can 1DIR and 2DIR be tied together for unified 16-bit operation?
Yes - connecting 1DIR and 2DIR enables synchronized 16-bit bidirectional data transfer. However, doing so forfeits independent control of the two 8-bit lanes. For applications requiring byte-lane arbitration (e.g., DDR address/command vs. data buses), keeping them separate preserves timing flexibility and avoids contention.
Is the 74AVC16T245EV/G,51 pin-compatible with older 74ALVC16T245 variants?
No - although functionally similar, the 74AVC16T245EV/G,51 uses updated internal ESD structures and tighter VIH/VIL thresholds optimized for 0.8 V operation. Pinout matches the 74AVC16T245 family (e.g., DGG/DGV packages) but is not backward compatible with ALVC-series layouts due to revised power pin placement and GND distribution.
