Product details
Overview
74AVC4T245PW,118 from Nexperia is a 4-bit dual-supply translating transceiver enabling bidirectional level translation between independent voltage domains (VCC(A) and VCC(B), each 0.8 V–3.6 V). It operates as two 2-bit or one 4-bit transceiver, with direction control (nDIR), output enable (nOE), and IOFF partial power-down support. Used in mixed-voltage SoC interconnects, such as FPGA-to-ASIC data buses requiring 1.2 V ↔ 3.3 V translation.
For engineers reviewing the 74AVC4T245PW,118 datasheet, 74AVC4T245PW,118 pinout, 74AVC4T245PW,118 application, or 74AVC4T245PW,118 equivalent, key selection criteria include configurable voltage translation range, 3-state isolation timing (tdis ≤ 13.7 ns at −40 °C to +125 °C), IOFF-enabled suspend mode, JEDEC-compliant low-voltage operation, and TSSOP16 package thermal performance.
Technical Context
The device implements dual-rail I/O architecture with nAn/nOE/nDIR referenced to VCC(A) and nBn referenced to VCC(B), enabling asymmetric voltage translation (e.g., 1.5 V A-side ↔ 2.5 V B-side). Its logic function table defines transmission direction via nDIR polarity and high-impedance isolation via active-low nOE.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) = GND, preventing backflow current and ensuring bus isolation in suspend mode. Propagation delay varies with supply pairing: tpd(A→B) ranges from 5.9 ns (VCC(A)=2.5 V, VCC(B)=3.3 V) to 14.5 ns (both at 0.8 V), per dynamic characterization tables.
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 - supports translation across JEDEC standards JESD8-12 through JESD8-B. |
| Max Data Rate | 380 Mbit/s - achievable for ≥1.8 V ↔ 3.3 V translation, enabling high-speed inter-die communication. |
| Propagation Delay | tpd(A→B) = 5.9 ns (min) at VCC(A)=2.5 V/VCC(B)=3.3 V - ensures sub-6 ns latency in critical data paths. |
| IOFF Leakage | ±1 μA max (VCC=0 V) - guarantees safe hot-swap and partial power-down without damaging back-current. |
| ESD Rating | HBM >8000 V, CDM >1000 V - meets industrial-grade robustness requirements for board-level handling. |
| Operating Temp | −40 °C to +125 °C - qualified for automotive under-hood and industrial control applications. |
| Package | TSSOP16 (SOT403-1), 4.4 mm body width - surface-mount compatible with standard reflow profiles and IPC-7351B land patterns. |
Pinout & Package
TSSOP16 package (SOT403-1) with 0.65 mm pitch, 16-lead plastic thin shrink small outline, body width 4.4 mm, rated for −40 °C to +125 °C operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for A-side I/O (nAn, nDIR, nOE); sets input thresholds and output drive strength on A port. |
| 2 | 1DIR | Direction control for first 2-bit channel: HIGH enables A→B, LOW enables B→A. |
| 3 | 2DIR | Direction control for second 2-bit channel: independent of 1DIR for flexible partitioning. |
| 4 | 1A1 | Data terminal A1 of first channel - bidirectional I/O referenced to VCC(A). |
| 5 | 1A2 | Data terminal A2 of first channel - paired with 1B1/1B2 for 2-bit translation. |
| 6 | 2A1 | Data terminal A1 of second channel - electrically isolated from first channel. |
| 7 | 2A2 | Data terminal A2 of second channel - supports independent voltage translation setup. |
| 8 | GND | Ground reference for both supply domains; all GND pins must be connected to system 0 V. |
| 9 | GND | Second ground pin - reduces ground bounce in high-speed switching; mandatory connection. |
| 10 | 2B2 | Data terminal B2 of second channel - referenced to VCC(B); output voltage swing follows VCC(B). |
| 11 | 2B1 | Data terminal B1 of second channel - completes 2-bit B-side interface. |
| 12 | 1B2 | Data terminal B2 of first channel - receives/transmits relative to VCC(B) rail. |
| 13 | 1B1 | Data terminal B1 of first channel - forms full 4-bit bidirectional path with A-side pins. |
| 14 | 2OE | Active-low output enable for second channel - drives 2B1/2B2 into high-Z when HIGH. |
| 15 | 1OE | Active-low output enable for first channel - independently isolates 1B1/1B2 from B-bus. |
| 16 | VCC(B) | Supply for B-side I/O (nBn); defines logic thresholds and output levels on B port. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail translation | Independent VCC(A) and VCC(B) supplies allow simultaneous 0.8 V ↔ 3.3 V, 1.2 V ↔ 2.5 V, or other combinations without external level shifters. |
| IOFF suspend mode | Automatically places all I/Os in high-impedance state when either VCC drops to GND - eliminates need for external isolation switches in power-gated subsystems. |
| JEDEC compliance | Meets JESD8-12 (0.8–1.3 V), JESD8-11 (0.9–1.65 V), JESD8-7 (1.2–1.95 V), JESD8-5 (1.8–2.7 V), and JESD8-B (2.7–3.6 V) - simplifies qualification across voltage tiers. |
| High-speed timing | 380 Mbit/s max data rate with tpd down to 5.9 ns and tdis ≤ 13.7 ns over full temperature range - suitable for DDR interface bridging and real-time sensor aggregation. |
| Robust ESD protection | HBM >8 kV and CDM >1 kV - exceeds IEC 61000-4-2 Level 4 requirements, reducing field failure risk in handling and assembly. |

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 |
|---|---|---|---|
| SN74AVC4T245PWR | TSSOP16 package, identical pinout and electrical specs; TI version qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C), not +125 °C. | Limited to automotive cabin applications; lacks extended temperature validation for under-hood use. | Select if AEC-Q100 Grade 2 suffices and TI supply chain preference applies; verify thermal derating above 105 °C. |
| 74LVC4T245PW,118 | Same TSSOP16 footprint but single-supply (VCC only); no dual-rail capability - requires external level-shifting for mixed-voltage interfaces. | Only suitable for same-voltage-domain buffering; cannot replace 74AVC4T245PW,118 in true level-translation roles. | Use only for intra-rail signal conditioning where voltage domains match; not a functional substitute for bidirectional translation. |

FAQ
What is the minimum valid supply voltage for reliable operation of 74AVC4T245PW,118?
The device is fully specified from 0.8 V to 3.6 V on both VCC(A) and VCC(B) rails. At 0.8 V, static parameters including VIH (0.70 × VCC(A)) and VOL (0.07 V) remain guaranteed, and dynamic operation supports up to 150 Mbit/s (1.1 V ↔ 1.2 V). Operation below 0.8 V is outside specification and not characterized.
How does the IOFF feature behave when only VCC(A) is powered and VCC(B) = 0 V?
When VCC(B) = 0 V and VCC(A) is active, the B-side I/Os (1B1, 1B2, 2B1, 2B2) enter high-impedance OFF-state regardless of nDIR or nOE state. The A-side pins remain functional but cannot drive B-side outputs, and IOFF leakage is limited to ±1 μA - preventing backfeed into the unpowered domain.
Can 74AVC4T245PW,118 translate between 3.3 V and 5 V logic domains?
No. Absolute maximum VCC ratings are +4.6 V, but recommended operating range is strictly 0.8 V–3.6 V per rail. Inputs tolerate up to 3.6 V, so 5 V signals would violate VI limits and risk damage. For 3.3 V ↔ 5 V translation, a dedicated 5 V-tolerant transceiver (e.g., 74LVT245) is required.
Is the TSSOP16 package (SOT403-1) RoHS and REACH compliant?
Yes. Nexperia confirms the 74AVC4T245PW,118 in SOT403-1 packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound - documented in Nexperia's official compliance statements PN900000001 and PN900000002.
