Product details
Overview
74AVC16T245DGG,118 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 supports voltage translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V domains, operates from −40 °C to +125 °C, and delivers up to 380 Mbit/s data rate for ≥1.8 V ↔ 3.3 V interfaces in high-speed memory or FPGA I/O bridging applications.
For engineers reviewing the 74AVC16T245DGG,118 datasheet, 74AVC16T245DGG,118 pinout, 74AVC16T245DGG,118 application, or 74AVC16T245DGG,118 equivalent, this device is selected for low-voltage mixed-domain bus interfacing where partial power-down (IOFF), suspend-mode isolation, and JEDEC-compliant voltage translation across two independent 8-bit channels are required.
Technical Context
The device implements two independent 8-bit transceiver sections (nA/nB ports), each with dedicated direction (nDIR) and output enable (nOE) controls referenced to VCC(A). Data flow is bidirectional: HIGH on nDIR routes nAn → nBn; LOW routes nBn → nAn. Both ports support simultaneous operation at different supply voltages.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing all I/Os into high-impedance OFF-state. IOFF circuitry prevents backflow current during partial power-down, meeting JESD78 Class II latch-up immunity (>100 mA) and enabling hot-swap compatibility in multi-rail systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) / VCC(B) Range | 0.8 V to 3.6 V independently - enables translation between any pair of common logic voltages (e.g., 1.2 V FPGA ↔ 3.3 V peripheral) |
| Max Data Rate | 380 Mbit/s (≥1.8 V ↔ 3.3 V) - supports DDR2/DDR3 memory interface clocking and high-speed serial bus bridging |
| Propagation Delay | 2.7 ns min to 16.4 ns max (−40 °C to +125 °C) - ensures timing closure in sub-ns critical control paths |
| IOFF Leakage | ±5 μA max at −40 °C to +125 °C - guarantees safe isolation during rail sequencing or standby |
| ESD Protection | HBM >8000 V, CDM >1000 V - meets industrial-grade robustness requirements without external protection |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and telecom infrastructure use |
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, and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH selects nAn→nBn; LOW selects nBn→nAn - enables dynamic bus arbitration per 8-bit segment |
| 1OE, 2OE | Output enable input | Active-LOW disables both A and B ports simultaneously - provides synchronized tri-state control for bus sharing |
| 1A1–1A8, 2A1–2A8 | A-side I/O terminals | Referenced to VCC(A); tolerate inputs up to 3.6 V - allows direct connection to higher-voltage legacy peripherals |
| 1B1–1B8, 2B1–2B8 | B-side I/O terminals | Referenced to VCC(B); support independent voltage domain - isolates noise and ground bounce between subsystems |
| VCC(A), VCC(B) | Supply rails | Decoupled power inputs - require separate local bypass capacitors to suppress cross-rail coupling |
| GND (pins 4,10,15,21,28,34,39,45) | Ground reference | Eight dedicated GND pins - minimize ground impedance and improve signal integrity in high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit transceivers | Enables split-bus architecture: one section for address/data, another for control/status signals |
| Configurable voltage translation | Supports 16 distinct voltage-pair combinations (e.g., 1.5 V ↔ 2.5 V) without external level shifters |
| IOFF partial power-down | Prevents damaging back-current when VCC(A) or VCC(B) is unpowered - essential for hot-plug and rail-sequencing designs |
| Suspend mode | Automatic high-Z state when either supply drops to GND - eliminates need for external power-good monitoring |
| JEDEC compliance | Meets JESD8-12 through JESD8-B standards - ensures interoperability with certified 0.8 V to 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 |
|---|---|---|---|
| SN74AVC16T245DGGR | Same functionality, TSSOP48 package, but rated only to +85 °C and lacks −40 °C to +125 °C qualification | Not suitable for automotive or extended-temperature industrial deployments | Select only for commercial-grade applications where ambient temperature stays below 85 °C |
| 74LVC16T245PW,118 | Single-supply (1.2 V to 3.6 V), no independent VCC(A)/VCC(B); max data rate 200 Mbit/s | Lacks true bidirectional mixed-voltage translation - requires external biasing for asymmetric domains | Choose only when both sides operate at identical voltage and lower speed suffices |

FAQ
What is the minimum recommended load capacitance for stable 380 Mbit/s operation?
The device achieves its maximum 380 Mbit/s data rate with CL ≤ 15 pF and VI transition rates ≤ 1.0 ns/V, per test conditions in Table 15. Operation above 15 pF increases propagation delay nonlinearly, reducing usable bandwidth; layout must minimize trace capacitance and avoid stubs.
Can VCC(A) and VCC(B) be powered in any sequence during startup?
Yes - IOFF and suspend mode ensure safe operation regardless of power-up order. If VCC(A) ramps before VCC(B), the A-side I/Os remain high-Z until VCC(B) stabilizes, preventing contention or back-driving. No external sequencing circuitry is required.
Does the device support hot-swap insertion while system power is active?
Yes - the IOFF circuitry limits off-state leakage to ±5 μA max at +125 °C, and HBM ESD rating exceeds 8000 V, enabling safe insertion into live backplanes or modular I/O carriers without disrupting upstream logic.
How does the 74AVC16T245DGG,118 handle ground potential differences between A and B domains?
It does not compensate for ground offset - the device assumes GND is common across both domains. Ground differential > ±0.3 V may cause timing skew or increased jitter; external isolation (e.g., digital isolators) is required if domains have independent ground planes.
