Product details
Overview
74AVCH16T245DGV:11 from Nexperia is a 16-bit dual-supply bidirectional voltage-translating transceiver with 3-state outputs, independent VCC(A) and VCC(B) rails (0.8 V–3.6 V), bus-hold circuitry, and IOFF partial power-down protection. It operates across −40 °C to +125 °C and supports up to 380 Mbit/s data rates for 1.8 V–3.3 V translation, enabling inter-voltage domain communication in mixed-supply SoC interfaces.
For engineers reviewing the 74AVCH16T245DGV:11 datasheet, 74AVCH16T245DGV:11 pinout, 74AVCH16T245DGV:11 application, or 74AVCH16T245DGV:11 equivalent, this page delivers verified electrical specs, TSSOP48 package details, direction-control logic behavior, suspend-mode operation, and real-world substitution guidance for high-reliability industrial and automotive interface designs.
Technical Context
The device implements two independent 8-bit transceiver blocks (1A/1B and 2A/2B), each with dedicated DIR and OE controls referenced to their respective supply domains (VCC(A) for A-side signals, VCC(B) for B-side). Direction is determined by DIR level: HIGH enables A→B flow; LOW enables B→A flow.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is at GND, preventing backflow current during partial power-down. Bus-hold circuitry maintains valid logic levels on floating A/B port inputs without external resistors, supporting robust operation in unterminated or hot-swap scenarios.
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 domains |
| Max Data Rate | 380 Mbit/s - achievable for 1.8 V → 3.3 V or 3.3 V → 1.8 V translation under typical conditions |
| Propagation Delay | 2.7 ns min to 10.2 ns max - varies with supply pair and direction; nAn→nBn is faster than reverse path at matched voltages |
| IOFF Leakage | ±1 µA max - ensures safe isolation during power sequencing or suspend mode |
| ESD Rating | HBM >8 kV - meets JESD22-A114F Class 3B for robust handling in manufacturing and field environments |
| Operating Temp | −40 °C to +125 °C - qualified for automotive under-hood and industrial control applications |
| Bus-Hold Current | ±100 µA at 3.0 V - sustains valid logic states on unused I/Os without pull resistors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVCH16T245DGGR | Same functionality and pinout; TI part in identical TSSOP48 package; VCC range 1.2 V–3.6 V (no 0.8 V support) | Limited to ≥1.2 V domains; not suitable for ultra-low-voltage AI accelerators or advanced mobile SoCs | Select when design uses only 1.2 V+ rails and TI supply chain preference applies |
| 74LVC16T245PWJ | Nexperia LVC variant; fixed 1.65 V–3.6 V VCC range; lower ESD (HBM 2 kV); no bus-hold | Requires external pull resistors; unsuitable for floating-bus or hot-swap use cases | Choose for cost-sensitive, non-suspend, non-floating applications where 1.65 V minimum is acceptable |
Compared with SN74AVCH16T245DGGR and 74LVC16T245PWJ, the 74AVCH16T245DGV:11 uniquely supports 0.8 V operation and integrated bus-hold - making it the only option for next-generation low-power embedded systems requiring both ultra-low-voltage compatibility and robust un-driven input handling.

FAQ
What voltage ranges does the 74AVCH16T245DGV:11 support on its VCC(A) and VCC(B) supplies?
The 74AVCH16T245DGV:11 supports independent VCC(A) and VCC(B) supplies from 0.8 V to 3.6 V each. This allows translation between any combination of standard logic voltages including 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V. Operation outside this range violates absolute maximum ratings and may cause permanent damage to the 74AVCH16T245DGV:11.
How does the 74AVCH16T245DGV:11 behave when one supply rail is powered down?
When either VCC(A) or VCC(B) is at GND, the 74AVCH16T245DGV:11 enters suspend mode: all A- and B-side outputs go to high-impedance OFF-state, and IOFF circuitry prevents backflow current. This behavior is guaranteed across −40 °C to +125 °C and is intrinsic to the 74AVCH16T245DGV:11's design - no external control is needed.
Does the 74AVCH16T245DGV:11 require external pull-up or pull-down resistors on its I/O pins?
No. The 74AVCH16T245DGV:11 integrates active bus-hold circuitry on all A- and B-side data I/Os, which maintains valid logic states on floating inputs without external resistors. This feature is always active on the powered-up side and eliminates 16 discrete components - a key differentiator of the 74AVCH16T245DGV:11 versus basic transceivers.
What is the maximum data rate supported by the 74AVCH16T245DGV:11, and under what conditions?
The 74AVCH16T245DGV:11 achieves up to 380 Mbit/s when translating between 1.8 V and 3.3 V (or vice versa) under typical conditions. Lower rates apply for other combinations: 200 Mbit/s for ≥1.1 V ↔ 3.3 V, and 100 Mbit/s for ≥1.1 V ↔ 1.2 V. These values are measured with defined load and transition conditions per the official 74AVCH16T245DGV:11 datasheet.
Is the 74AVCH16T245DGV:11 pin-compatible with other members of the 74AVCH16T245 family?
Yes - the 74AVCH16T245DGV:11 shares identical pinout and function with other TSSOP48 variants like 74AVCH16T245DGG, differing only in tape-and-reel packaging and minor marking. However, it is not pin-compatible with VFBGA56 (74AVCH16T245EV) or HXQFN60 (74AVCH16T245BX) packages due to distinct land patterns and terminal layouts - PCB layout must match the TSSOP48 footprint for the 74AVCH16T245DGV:11.
