Product details
Overview
74AVC20T245DGG,118 from Nexperia is a 20-bit dual-supply translating transceiver enabling bidirectional voltage level translation between independent 0.8 V–3.6 V domains. It supports two 10-bit or one 20-bit configuration, features separate VCC(A) and VCC(B), four I/O port groups (1An/1Bn/2An/2Bn), dual direction (nDIR) and output enable (nOE) controls, and operates across –40 °C to +125 °C - used in FPGA-to-ASIC interconnects with mixed-voltage I/O banks.
For engineers reviewing the 74AVC20T245DGG,118 datasheet, 74AVC20T245DGG,118 pinout, 74AVC20T245DGG,118 application, or 74AVC20T245DGG,118 equivalent, key selection criteria include configurable bi-directional translation across 0.8 V/1.2 V/1.5 V/1.8 V/2.5 V/3.3 V nodes, IOFF-enabled partial power-down, suspend-mode high-impedance outputs during supply loss, and JEDEC-compliant operation per JESD8-12 through JESD8-B.
Technical Context
The device implements two independent 10-bit transceiver blocks, each with dedicated nDIR and nOE inputs referenced to VCC(A). Data flow direction is controlled per block: HIGH on nDIR enables A→B transmission; LOW enables B→A. Output enable is active-low and forces all associated ports into high-impedance state.
Suspend mode activates when either VCC(A) or VCC(B) = GND, automatically placing all I/O ports in high-impedance OFF-state regardless of control inputs. The IOFF circuitry ensures leakage current remains ≤ ±1 μA under power-down conditions, preventing damaging backflow currents during hot-swap or staggered power sequencing.
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 between any low-voltage node pair (e.g., 1.2 V FPGA ↔ 3.3 V peripheral) |
| Max Data Rate | 380 Mbit/s (≥1.8 V ↔ 3.3 V) - supports high-speed DDR interface bridging without external clocking |
| Propagation Delay | 2.9 ns–11.9 ns (VCC(A)/VCC(B) = 3.3 V/3.3 V to 1.1 V/1.2 V, –40 °C to +85 °C) - ensures timing closure in sub-ns margin designs |
| IOFF Leakage | ≤ ±1 μA at VCC = 0 V - guarantees safe partial power-down during system sleep or reset sequences |
| ESD Rating | HBM > 8000 V, CDM > 1000 V - meets industrial-grade robustness for board-level handling and field operation |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and telecom infrastructure use |
Pinout & Package
TSSOP56 (SOT364-1) package: 56-pin plastic thin shrink small outline, 6.1 mm body width, 0.5 mm pitch, lead finish matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Referenced to VCC(A); HIGH = 1An/2An → 1Bn/2Bn; LOW = reverse flow |
| 1OE, 2OE | Output enable input (active LOW) | Referenced to VCC(A); asserts high-impedance on respective 10-bit port group |
| 1A1–1A10, 2A1–2A10 | Data I/O (A-side) | Referenced to VCC(A); connect to 0.8 V–3.6 V domain A logic (e.g., FPGA core I/O) |
| 1B1–1B10, 2B1–2B10 | Data I/O (B-side) | Referenced to VCC(B); connect to independent 0.8 V–3.6 V domain B logic (e.g., sensor MCU) |
| VCC(A), VCC(B) | Independent supply rails | Decoupled power domains allow simultaneous operation at different voltages; no shared rail required |
| GND (pins 4,11,18,25,32,39,46,53) | Ground reference | All eight GND pins must be connected to PCB ground plane for signal integrity and thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Enables bidirectional data transfer between mismatched voltage domains without external level-shifting components |
| IOFF partial power-down | Prevents back-current flow when either VCC(A) or VCC(B) is unpowered - critical for hot-plug and power-gating systems |
| Suspend mode | Automatic high-Z on all I/O when either supply drops to GND - eliminates bus contention during brown-out or sequencing faults |
| JEDEC compliance | Validated across five JEDEC standards (JESD8-12 to JESD8-B) - ensures interoperability with legacy and next-gen low-voltage logic families |
| High-speed timing | Sub-3 ns propagation delay at 3.3 V/3.3 V enables use in 300+ MHz data paths without added timing budget overhead |
Applications

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 |
|---|---|---|---|
| SN74AVC20T245RGYR | 64-pin QFN (7 mm × 7 mm); higher thermal performance (θJA = 36 °C/W vs. TSSOP's 60 °C/W); same electrical specs | Better suited for high-density, thermally constrained layouts where PCB real estate is limited and airflow is restricted | Select when board space is premium and junction temperature must stay <105 °C at full 380 Mbit/s load |
| 74LVC20T245DGG,118 | Narrower supply range (1.65 V–3.6 V); no 0.8 V/1.2 V support; lower max speed (240 Mbit/s); identical pinout and footprint | Limited to 1.8 V+ systems; cannot replace in ultra-low-voltage FPGA or battery-powered edge node designs | Choose only for cost-sensitive 3.3 V-only applications where 0.8 V–1.5 V compatibility is unnecessary |
Compared with SN74AVC20T245RGYR, the 74AVC20T245DGG,118 offers identical logic functionality in a lower-cost TSSOP package but requires more PCB area and has higher thermal resistance; versus 74LVC20T245DGG,118, it delivers broader voltage flexibility and 58% higher bandwidth at the expense of slightly higher static current.

FAQ
Can 74AVC20T245DGG,118 translate between 0.8 V and 3.3 V in both directions simultaneously?
Yes. With VCC(A) = 0.8 V and VCC(B) = 3.3 V, the device supports bidirectional translation: 1An/2An inputs accept 0.8 V logic levels and drive 1Bn/2Bn outputs at 3.3 V, while 1Bn/2Bn inputs accept 3.3 V logic and drive 1An/2An outputs at 0.8 V - verified per JESD8-12 and functional table in datasheet Rev. 9.
What happens to outputs when VCC(A) = 0 V and VCC(B) = 3.3 V?
All 1An/2An and 1Bn/2Bn ports enter high-impedance OFF-state automatically due to suspend mode activation - confirmed in Section 6 function table and Section 1 general description. No external pull-ups/downs are needed to prevent bus contention.
Is the TSSOP56 package RoHS and REACH compliant?
Yes. The 74AVC20T245DGG,118 (SOT364-1) package meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin termination and halogen-free molding compound - documented in Nexperia's Material Declaration (DocID: MDD-74AVC20T245).
How does IOFF behavior differ from standard 3-state disable?
IOFF actively disables output buffers and clamps leakage to ≤ ±1 μA even when VCC(A) or VCC(B) = 0 V - unlike standard 3-state which only gates drivers but leaves input structures vulnerable to back-current. This is validated in Table 7 (IOFF parameter) and Section 1.
