Product details
Overview
74AVC16T245EV/G518 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 functions as two independent 8-bit transceivers or one unified 16-bit unit, enabling voltage translation between 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V domains. Used in mixed-voltage memory interfaces and FPGA I/O bridging where dynamic bus direction control and partial power-down are required.
For engineers reviewing the 74AVC16T245EV/G518 datasheet, 74AVC16T245EV/G518 pinout, 74AVC16T245EV/G518 application, or 74AVC16T245EV/G518 equivalent, key selection criteria include configurable voltage translation range, IOFF-enabled suspend mode, maximum data rate (380 Mbit/s at ≥1.8 V→3.3 V), JEDEC compliance across five voltage classes, and TSSOP48 package thermal derating above 109 °C.
Technical Context
The device implements dual-rail I/O architecture with separate input-reference domains: nAn, nDIR, and nOE inputs referenced to VCC(A); nBn inputs referenced to VCC(B). Direction control (nDIR) selects data flow either from A-to-B (HIGH) or B-to-A (LOW), while nOE (active LOW) enables/disables outputs into high-impedance state.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing all nAn and nBn ports into high-impedance OFF-state. The integrated IOFF circuit prevents damaging backflow current during partial power-down, meeting JESD78 Class II latch-up performance (>100 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) / VCC(B) Range | 0.8 V to 3.6 V each - enables translation between any pair of standard low-voltage logic domains (e.g., 1.2 V ↔ 3.3 V). |
| Max Data Rate | 380 Mbit/s - achievable only for ≥1.8 V to 3.3 V translation; supports high-speed DDR memory bus interfacing. |
| IOFF Current | ±5 μA max at -40 °C to +125 °C - ensures safe partial power-down without backfeed in hot-swap or sleep-mode systems. |
| Propagation Delay | 2.7 ns min to 16.4 ns max - varies by supply pair and temperature; worst-case tpd = 16.4 ns at -40 °C to +125 °C, VCC(A)=1.1–1.3 V, VCC(B)=3.3 V. |
| ESD Protection | HBM >8000 V, CDM >1000 V - exceeds JEDEC JS-001/JS-002 requirements for robust board-level handling. |
| Operating Temp | -40 °C to +125 °C - qualified for automotive under-hood and industrial control applications requiring extended thermal margin. |
| Input Voltage Range | 0 V to 3.6 V - allows 3.3 V-tolerant inputs even when VCC(A) or VCC(B) is at 0.8 V, simplifying interface design. |
Pinout & Package
TSSOP48 plastic thin shrink small outline package (SOT362-1), 48 leads, body width 6.1 mm, lead pitch 0.5 mm. Thermal derating: 12.2 mW/K above 109 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH selects A→B data flow; LOW selects B→A - enables per-port bidirectional bus arbitration. |
| 1OE, 2OE | Output enable input | Active-LOW disables both A and B ports on respective 8-bit sections - provides granular 3-state control for multiplexed buses. |
| 1A1–1A8, 2A1–2A8 | Data I/O port A | Referenced to VCC(A); bidirectional with direction set by nDIR - connects to processor/FPGA core logic domain. |
| 1B1–1B8, 2B1–2B8 | Data I/O port B | Referenced to VCC(B); bidirectional with direction set by nDIR - interfaces to memory/peripheral operating at different voltage. |
| VCC(A), VCC(B) | Independent supply rails | Each powers its associated I/O bank and input buffers - eliminates need for external level shifters in mixed-voltage systems. |
| GND (pins 4,10,15,21,28,34,39,45) | Ground reference | All eight GND pins must be connected to system ground - ensures low-impedance return path and minimizes ground bounce in high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail voltage translation | Independent 0.8 V–3.6 V supplies on A and B sides enable interoperability across five JEDEC voltage standards (JESD8-12 through JESD8-B). |
| IOFF partial power-down | Automatically disables outputs and blocks backflow current when either VCC rail is at GND - essential for hot-plug and battery-backed subsystems. |
| Configurable 8/16-bit operation | Two independent nDIR/nOE pairs allow use as two 8-bit transceivers (e.g., separate address/data paths) or one 16-bit unit (e.g., wide parallel bus). |
| High-speed timing | 380 Mbit/s max data rate and sub-3 ns typical propagation delay at 3.3 V support DDR2/DDR3 memory interface speeds. |
| Robust ESD immunity | HBM >8 kV and CDM >1 kV meet stringent IEC 61000-4-2 requirements - reduces field failure risk in manufacturing and end-use environments. |

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 | TI part in TVSOP48 (SOT480-1); identical electrical specs but 0.4 mm lead pitch and 4.4 mm body width. | Requires PCB redesign due to smaller footprint and tighter pitch; thermal derating differs (5.5 mW/K above 60 °C vs. 12.2 mW/K above 109 °C). | Select if existing layout uses TI-compatible TVSOP48 or requires lower profile; verify thermal management at >60 °C. |
| 74LVC16T245PW | Nexperia LVC variant in TSSOP48; narrower VCC range (1.2 V–3.6 V), no 0.8 V support, and no IOFF circuitry. | Cannot operate below 1.2 V or enter true suspend mode; unsuitable for ultra-low-power or partial power-down systems. | Choose only for cost-sensitive 1.2 V+ applications where IOFF and sub-1.2 V operation are unnecessary. |
Compared with SN74AVC16T245DGGR, the 74AVC16T245EV/G518 offers superior thermal headroom above 109 °C and mechanical compatibility with legacy TSSOP48 footprints; versus 74LVC16T245PW, it delivers critical 0.8 V operation and IOFF-enabled safety for battery-backed and automotive systems.

FAQ
What is the minimum valid VCC(A) and VCC(B) voltage for functional operation?
The device operates down to 0.8 V on either rail, with guaranteed functionality across the full -40 °C to +125 °C range. At 0.8 V, static parameters such as VIH/VIL and VOH/VOL remain specified, and IOFF remains active. Below 0.8 V, behavior is not characterized and may result in undefined output states or increased leakage.
How does the IOFF feature behave when only VCC(A) is powered?
When VCC(A) is powered and VCC(B) = GND, the IOFF circuit disables all nBn outputs, clamping them to high-impedance regardless of nDIR/nOE state. Input leakage on nBn pins is limited to ±5 μA max, preventing current backflow into the unpowered VCC(B) domain - a critical safety function in hot-swap systems.
Can 74AVC16T245EV/G518 translate between 0.8 V and 3.3 V bidirectionally at 380 Mbit/s?
No. The 380 Mbit/s maximum data rate applies only to translations where both VCC(A) and VCC(B) are ≥1.8 V (e.g., 1.8 V ↔ 3.3 V). For 0.8 V ↔ 3.3 V, the rated speed is 100 Mbit/s - confirmed in Table 2 of the datasheet - due to reduced noise margins and slower switching at the lowest VCC.
Is the TSSOP48 package RoHS-compliant and lead-free?
Yes. The SOT362-1 package used for 74AVC16T245EV/G518 is lead-free and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No 1907/2006. Nexperia confirms homogeneous material declarations and IMDS reporting for this part number.
