Product details
Overview
74AVC16T245DGV,112 from Nexperia is a 16-bit dual-supply translating transceiver with bidirectional level translation, 3-state outputs, and independent VCC(A) and VCC(B) rails (0.8 V to 3.6 V). It supports two 8-bit or one 16-bit data path, features per-port direction (nDIR) and output enable (nOE), and implements IOFF for partial power-down. It enables voltage translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V domains in high-density memory and processor interconnects.
For engineers reviewing the 74AVC16T245DGV,112 datasheet, 74AVC16T245DGV,112 pinout, 74AVC16T245DGV,112 application, or 74AVC16T245DGV,112 equivalent, key selection criteria include configurable dual-rail operation, suspend-mode behavior when either supply is at GND, JEDEC-compliant voltage translation across six logic families, and guaranteed timing performance over –40 °C to +125 °C.
Technical Context
The device operates as two independent 8-bit transceivers (Port A: nA1–nA8; Port B: nB1–nB8), each with dedicated nDIR and nOE controls. Direction control is asynchronous: HIGH on nDIR routes data from nAn to nBn; LOW routes from nBn to nAn. Output enable is active-low: HIGH on nOE forces both ports into high-impedance OFF-state.
Suspend mode activates when either VCC(A) or VCC(B) = GND, placing all I/O pins (nAn, nBn) in high-impedance state regardless of nDIR/nOE. The IOFF circuit disables outputs during power-down, blocking damaging backflow current and meeting JESD78 Class II latch-up immunity (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 0.8 V to 3.6 V - powers nAn, nDIR, nOE inputs and defines their logic thresholds |
| VCC(B) Range | 0.8 V to 3.6 V - powers nBn inputs and defines their logic thresholds |
| Max Data Rate | 380 Mbit/s - achievable only for ≥1.8 V ↔ 3.3 V translation; lower rates apply for sub-1.8 V interfaces |
| Propagation Delay | 2.7 ns to 11.8 ns - varies by supply pair and direction; worst-case (nAn→nBn, VCC(A)=3.3 V/VCC(B)=1.2 V) is 8.0 ns @ –40 °C to +85 °C |
| IOFF Leakage | ±5 μA max - ensures safe bus isolation during partial power-down without external pull-ups |
| Operating Temp | –40 °C to +125 °C - qualified for automotive under-hood and industrial control applications |
| ESD Rating | HBM >8000 V, CDM >1000 V - robust handling in automated assembly and field-replaceable modules |
Pinout & Package
74AVC16T245DGV,112 uses the TVSOP48 package (SOT480-1): 48-pin plastic thin shrink small outline, 4.4 mm body width, 0.4 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Asynchronous control: HIGH selects nAn → nBn; LOW selects nBn → nAn per port |
| 1OE, 2OE | Output enable input (active LOW) | Drives both nAn and nBn ports into high-impedance when HIGH |
| nA1–nA8, nB1–nB8 | Bidirectional data I/O | Each pair forms a translation channel; referenced to VCC(A) and VCC(B) respectively |
| VCC(A), VCC(B) | Independent supply rails | VCC(A) powers nAn/nDIR/nOE logic; VCC(B) powers nBn logic; enables mixed-voltage interconnect |
| GND (pins 4,10,15,21,28,34,39,45) | Ground reference | All eight GND pins must be connected to system ground for signal integrity and thermal dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail voltage translation | Supports simultaneous 0.8 V ↔ 3.3 V, 1.2 V ↔ 1.8 V, and other combinations without external level shifters |
| IOFF partial power-down | Prevents back-current flow when either VCC rail is powered off - critical for hot-swap and low-power sleep states |
| Suspend mode | Automatically places all I/O in high-Z if VCC(A) = GND or VCC(B) = GND - eliminates need for external isolation logic |
| JEDEC compliance | Meets JESD8-12 through JESD8-B standards - ensures interoperability across 0.8 V to 3.6 V logic families |
| High-speed timing | Sub-3 ns propagation delay in optimal 3.3 V ↔ 2.5 V configurations - suitable for DDR memory interface buffering |
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 |
|---|---|---|---|
| SN74AVC16T245DGGR | Same functionality and pinout; TSSOP48 (SOT362-1) package, 6.1 mm body width vs. TVSOP48's 4.4 mm | Higher thermal resistance (12.2 mW/K derating above 109 °C vs. 5.5 mW/K above 60 °C); less suitable for ultra-dense layouts | Select when board space allows larger footprint and higher power dissipation tolerance is needed |
| 74LVC16T245DGV,118 | Single-supply (1.65 V–3.6 V), no VCC(B) independence; lacks suspend mode and IOFF | Cannot translate below 1.65 V; unsuitable for 0.8 V/1.2 V interfaces or partial power-down systems | Select only for cost-sensitive 1.8 V/3.3 V-only designs where dual-rail flexibility is unnecessary |
Compared with SN74AVC16T245DGGR, the 74AVC16T245DGV,112 offers superior board density and lower thermal derating threshold; compared with 74LVC16T245DGV,118, it delivers true sub-1 V compatibility and hardware-enforced power-down safety - making it the sole choice for mixed-voltage, hot-swap, or automotive-grade designs.

FAQ
What is the minimum valid VCC(A)–VCC(B) voltage differential for reliable operation?
The device requires both VCC(A) and VCC(B) to be within 0.8 V to 3.6 V, but no minimum differential is specified. Operation is valid even at identical voltages (e.g., 1.8 V on both rails), and translation works across any combination in that range - including 0.8 V ↔ 3.3 V. The function table confirms correct behavior down to 0.8 V on either rail.
How does suspend mode behave when only VCC(A) is powered and VCC(B) = GND?
When VCC(B) = GND (regardless of VCC(A) value), the device enters suspend mode: all nBn pins go high-impedance, and nAn pins also enter high-Z - even if nOE is LOW and nDIR is asserted. This prevents back-driving of the unpowered B-side bus and is hardware-enforced, requiring no software intervention.
Can 74AVC16T245DGV,112 drive standard 50 Ω transmission lines directly?
No. Its outputs are designed for CMOS loading (CL ≤ 15 pF typical), not 50 Ω termination. Driving 50 Ω lines would exceed its ±50 mA output current rating and distort signal edges. Use external series resistors (e.g., 33 Ω) or dedicated line drivers for controlled-impedance routing.
Is the 74AVC16T245DGV,112 pin-compatible with older 74ALVC or 74LVT series transceivers?
No. While functionally similar, pin assignments differ significantly - especially for VCC and GND distribution. The 74AVC16T245DGV,112 uses eight GND pins and dual VCC pins placed across the package, unlike legacy variants. PCB layout and schematic symbols must be updated to match the SOT480-1 pinout.
