Product details
Overview
74AVC2T45GF,115 from Nexperia is a dual-bit, dual-supply voltage level translator/transceiver enabling bidirectional logic-level translation between 0.8 V and 3.6 V domains. It features independent VCC(A) and VCC(B) supplies, DIR-controlled data direction (A↔B), and IOFF circuitry for partial power-down protection. Used in mixed-voltage SoC interconnects, such as 1.8 V FPGA ↔ 3.3 V peripheral interfaces.
For engineers reviewing the 74AVC2T45GF,115 datasheet, 74AVC2T45GF,115 pinout, 74AVC2T45GF,115 application, or 74AVC2T45GF,115 equivalent, key selection criteria include dual-supply voltage flexibility (0.8–3.6 V per rail), 500 Mbit/s max data rate at 1.8–3.3 V translation, IOFF-enabled suspend mode, and TSSOP8 package compatibility with high-density PCB layouts.
Technical Context
The device implements a dual-rail CMOS transceiver architecture with separate input/output referencing: pins 1A, 2A, and DIR are referenced to VCC(A); pins 1B and 2B to VCC(B). Direction control is asynchronous and single-pin (DIR), where HIGH enables A→B and LOW enables B→A. No output enable (OE) pin is present, requiring external bus arbitration in bidirectional systems.
Suspend mode activates when either VCC(A) or VCC(B) = GND, forcing both ports into high-impedance OFF-state. The IOFF circuit prevents backflow current during partial power-down, meeting JEDEC JESD78 Class II latch-up immunity (>100 mA) and supporting hot-swap-capable designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply range (VCC(A)/VCC(B)) | 0.8 V to 3.6 V each - enables translation across all common low-voltage nodes (0.8/1.2/1.5/1.8/2.5/3.3 V). |
| Max data rate | 500 Mbit/s - achievable only for 1.8 V → 3.3 V or 3.3 V → 1.8 V translation; lower for sub-1.8 V rails. |
| Propagation delay (A→B) | Typ. 7.7 ns @ VCC(A)=1.8 V, VCC(B)=1.8 V - determines minimum clock period in synchronous level-shifting links. |
| IOFF leakage (VCC=0 V) | ±1 μA max - ensures negligible current flow during partial power-down, critical for battery-backed subsystems. |
| ESD rating (HBM) | >8000 V - exceeds JEDEC JS-001 Class 3B, suitable for handling in non-ESD-protected assembly environments. |
| Operating temperature | −40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control applications. |
| Input voltage tolerance | Up to 3.6 V on all I/O - allows safe interfacing with higher-voltage signals without external clamping. |
Pinout & Package
74AVC2T45GF,115 is supplied in the TSSOP8 (SOT505-2) package: plastic thin shrink small outline, 8 leads, 3 mm body width, 0.65 mm pitch, and exposed pad not present. Pin 1 is marked by a dot or bevelled corner adjacent to marking code "B45".
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply rail for port A and DIR input - defines logic thresholds for 1A, 2A, and DIR. |
| 2 | 1A | Bidirectional data terminal referenced to VCC(A); functions as input or output depending on DIR state. |
| 3 | 2A | Second bidirectional data terminal referenced to VCC(A); electrically isolated from 1A. |
| 4 | GND | Common reference ground for both supply domains and internal ESD structures. |
| 5 | DIR | Direction control input referenced to VCC(A); HIGH = A→B, LOW = B→A. |
| 6 | 2B | Bidirectional data terminal referenced to VCC(B); mirrors behavior of 1B relative to DIR. |
| 7 | 1B | Bidirectional data terminal referenced to VCC(B); active only when DIR enables B→A path. |
| 8 | VCC(B) | Supply rail for port B - defines logic thresholds for 1B and 2B; independent of VCC(A). |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Independent 0.8–3.6 V rails per port enable interoperability between disparate voltage domains without external level-shifters. |
| IOFF partial power-down | Automatically disables outputs and blocks backflow current when either VCC is at GND - eliminates need for external isolation switches. |
| Suspend mode | Guaranteed high-impedance on both ports during asymmetric power loss - prevents bus contention and signal corruption in fault conditions. |
| JEDEC compliance | Validated against JESD8-12 through JESD8-B standards - ensures interoperability with memory, processor, and interface ICs across voltage tiers. |
| Low dynamic power | CPD ≤ 17 pF @ 3.3 V - minimizes switching power in high-frequency data paths, critical for portable and thermally constrained designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC2T245RSWR | TI part uses same dual-supply architecture but specifies only −40 °C to +85 °C; IOFF leakage is ±5 μA (vs. ±1 μA typical for Nexperia). | Not qualified for automotive under-hood use; higher leakage may impact battery life in always-on sensor nodes. | Select when cost sensitivity outweighs extended temperature or ultra-low leakage requirements. |
| 74LVC2T45DP,118 | Nexperia's LVC variant has narrower VCC range (1.65–5.5 V), no IOFF, and slower max speed (420 Mbit/s); lacks suspend mode. | Cannot support 0.8 V or 1.2 V domains; unsuitable for partial power-down systems requiring backflow prevention. | Choose only for legacy 3.3 V ↔ 5 V translation where IOFF and sub-1.65 V operation are unnecessary. |
Compared with SN74AVC2T245RSWR and 74LVC2T45DP,118, the 74AVC2T45GF,115 uniquely combines −40 °C to +125 °C qualification, 0.8 V minimum supply, and sub-1 μA IOFF leakage-making it the sole option for next-gen automotive and industrial edge AI modules demanding robust mixed-voltage interoperability.

FAQ
What is the minimum valid supply voltage for reliable operation on either rail?
The 74AVC2T45GF,115 is fully specified down to 0.8 V on both VCC(A) and VCC(B), with guaranteed functionality including propagation delay, IOFF behavior, and input threshold tracking (VIH/VIL = 0.7×VCC and 0.3×VCC respectively). Operation below 0.8 V is not characterized and may result in undefined logic states or increased leakage.
Can the DIR pin be driven from a different voltage domain than VCC(A)?
No. The DIR input is strictly referenced to VCC(A), as confirmed in Section 6.2 of the datasheet. Driving DIR from a voltage outside the 0 V to VCC(A) range risks violating absolute maximum ratings and may cause latch-up or permanent damage. A level-shifter must be used if DIR originates from a non-VCC(A) domain.
How does suspend mode behave when only VCC(B) is powered?
When VCC(B) = GND and VCC(A) is active, the B-port terminals (1B, 2B) enter high-impedance OFF-state, while A-port terminals (1A, 2A) remain functional but cannot drive B-side loads. This configuration isolates the unpowered domain while preserving A-side logic integrity - a key feature for modular power sequencing in complex systems.
Is external termination required for 500 Mbit/s operation?
Yes. At 500 Mbit/s, signal integrity requires controlled-impedance routing (typically 50 Ω) and point-to-point topology. The device's 4.0 pF I/O capacitance (Table 7) and 7.7 ns propagation delay necessitate proper PCB layout: series resistors near drivers, minimized stub length, and matching load capacitance ≤15 pF as defined in the test circuit (Fig. 5).
