Product details
Overview
74AVCH16T245BX,518 from Nexperia is a 16-bit dual-supply translating transceiver with bidirectional level-shifting, 3-state outputs, and independent VCC(A)/VCC(B) rails (0.8 V–3.6 V). It operates as two 8-bit or one 16-bit transceiver, supports voltage translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V domains, and features bus-hold circuitry and IOFF for partial power-down in mixed-voltage SoC interconnects.
For engineers reviewing the 74AVCH16T245BX,518 datasheet, 74AVCH16T245BX,518 pinout, 74AVCH16T245BX,518 application, or 74AVCH16T245BX,518 equivalent, this device is selected for low-voltage bidirectional data bridging in DDR memory interfaces, FPGA-to-ASIC I/O expansion, and multi-rail industrial controllers where signal integrity, suspend-mode isolation, and elimination of external pull resistors are critical.
Technical Context
The device implements two independent 8-bit transceiver blocks (Port A/B), each with dedicated DIR and OE controls referenced to VCC(A). Direction control is asynchronous: nDIR HIGH enables A→B transmission; LOW enables B→A. Output enable (nOE, active LOW) places both sides in high-impedance state.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing all A/B outputs to high-impedance while preserving bus-hold on the powered side. IOFF circuitry disables outputs during power-down to prevent backflow current, and bus-hold sustains unused inputs at valid logic levels without external resistors.
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 - enables translation across six standard logic families without level-shifters. |
| Max Data Rate | 380 Mbit/s (≥1.8 V ↔ 3.3 V) - supports high-speed DDR I/O buffering in memory subsystems. |
| Propagation Delay | 2.7 ns–11.8 ns (VCC(A)/VCC(B) = 3.3 V/3.3 V, -40 °C to +125 °C) - ensures timing closure in sub-5 ns clock domains. |
| Bus-Hold Current | ±24 μA to ±500 μA (VCC = 1.2 V–3.6 V) - actively holds floating inputs, eliminating need for 10 kΩ pull-up/down resistors. |
| IOFF Leakage | ±5 μA max (VCC = 0 V, opposite rail powered) - prevents damaging back-current during hot-swap or staggered power sequencing. |
| ESD Protection | HBM > 8000 V, CDM > 1000 V - meets industrial-grade robustness requirements for board-level handling and field operation. |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and telecom infrastructure applications. |
Pinout & Package
TSSOP48 (SOT362-1) package: 48-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm pitch, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Referenced to VCC(A); HIGH selects A→B data flow, LOW selects B→A - enables dynamic bidirectional routing per port pair. |
| 1OE, 2OE | Output enable (active LOW) | Referenced to VCC(A); HIGH forces all associated A/B pins into high-impedance - supports time-multiplexed bus sharing. |
| 1A1–1A8, 2A1–2A8 | Data I/O (Port A) | Referenced to VCC(A); bidirectional signals tied to A-side logic domain - connects to FPGA core I/O or microcontroller GPIO banks. |
| 1B1–1B8, 2B1–2B8 | Data I/O (Port B) | Referenced to VCC(B); bidirectional signals tied to B-side logic domain - interfaces with memory, sensor, or legacy peripheral voltage rails. |
| VCC(A), VCC(B) | Independent supply rails | Decoupled power inputs allow simultaneous operation at different voltages - eliminates need for external voltage translators. |
| GND (pins 4,10,15,21,28,34,39,45) | Ground reference | Eight dedicated ground pins minimize ground bounce and improve noise immunity in high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Independent VCC(A)/VCC(B) rails support any combination of 0.8 V–3.6 V logic domains - reduces BOM count vs discrete level shifters. |
| Active bus-hold | Eliminates external pull resistors on all 32 I/O pins - saves PCB area, reduces assembly cost, and improves signal reliability on unterminated stubs. |
| IOFF partial power-down | Outputs disable safely when either supply is off - enables hot-plug capability and prevents latch-up in mixed-power systems. |
| Suspend mode | Automatic high-impedance output state when VCC(A) = GND or VCC(B) = GND - ensures clean isolation during power sequencing or fault conditions. |
| JEDEC compliance | Meets JESD8-12 through JESD8-B standards - guarantees interoperability with industry-standard 0.8 V–3.6 V logic families. |

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 |
|---|---|---|---|
| SN74AVCH16T245DGGR | Same function and pinout; TI version rated only to +85 °C (vs +125 °C); higher ICC at 3.3 V (185 μA vs 125 μA). | Limited to commercial/industrial ambient; unsuitable for under-hood automotive or high-temp industrial enclosures. | Select when temperature range ≤ +85 °C and TI supply chain preference applies. |
| 74LVC16T245PW,118 | Nexperia LVC variant; single 1.65 V–3.6 V supply; no VCC(B) independence; lacks bus-hold and IOFF. | Only supports uni-supply translation; requires external pull resistors and cannot isolate powered-down domains. | Select only for cost-sensitive, single-rail designs where suspend mode and bus-hold are unnecessary. |

FAQ
What voltage combinations are supported between VCC(A) and VCC(B)?
The 74AVCH16T245BX,518 supports any pairing of VCC(A) and VCC(B) within 0.8 V–3.6 V, including asymmetric configurations like 1.2 V ↔ 3.3 V or 1.8 V ↔ 2.5 V. JEDEC compliance covers JESD8-12 through JESD8-B standards, ensuring interoperability across all common logic families without derating.
How does bus-hold eliminate external pull resistors?
Integrated bus-hold circuitry sources or sinks up to ±500 μA (at 3.6 V) to maintain valid logic levels on unused or floating inputs. This replaces typical 10 kΩ pull-up/down resistors, reducing PCB footprint, assembly cost, and potential noise coupling from resistor networks.
Can the device operate with only one supply powered?
Yes - when either VCC(A) or VCC(B) is at GND, the device enters suspend mode: all outputs go high-impedance, but bus-hold remains active on the powered side. IOFF further blocks leakage current, enabling safe hot-swap and staggered power sequencing in modular systems.
What is the maximum guaranteed data rate at 1.5 V ↔ 2.5 V translation?
At 1.5 V ↔ 2.5 V translation, the device supports up to 200 Mbit/s, verified across -40 °C to +125 °C. This is confirmed by dynamic characterization tables (Table 12 and 13) showing tpd ≤ 5.9 ns (max) and tdis/ten ≤ 11.6 ns (max) under worst-case conditions.
