Product details
Overview
74AVCH2T45GN,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 two I/O ports (1A/2A referenced to VCC(A), 1B/2B to VCC(B)), DIR-controlled directionality, IOFF partial power-down, and active bus hold. Used in mixed-voltage SoC interconnects, such as 1.2 V FPGA ↔ 3.3 V peripheral interfaces.
For engineers reviewing the 74AVCH2T45GN,115 datasheet, 74AVCH2T45GN,115 pinout, 74AVCH2T45GN,115 application, or 74AVCH2T45GN,115 equivalent, key selection criteria include bidirectional translation capability, IOFF-enabled suspend mode, bus hold elimination of external resistors, and guaranteed operation across -40 °C to +125 °C.
Technical Context
The device implements a dual-rail transceiver architecture with independent VCC(A) and VCC(B) supplies, allowing asymmetric voltage translation (e.g., 1.5 V ↔ 2.5 V). DIR input-referenced solely to VCC(A)-controls signal flow direction: HIGH enables A→B, LOW enables B→A.
IOFF circuitry disables outputs when either supply drops to GND, preventing backflow current and ensuring safe partial power-down. Integrated bus hold maintains unused inputs at valid logic levels without external components, reducing BOM count and layout complexity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V per supply-supports translation between all common low-voltage nodes (0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V) |
| Max Data Rate | 500 Mbps (1.8 V → 3.3 V); enables high-speed interface bridging in modern embedded systems |
| Propagation Delay | ≤ 9.5 ns (A→B @ VCC(A)=3.3 V, VCC(B)=3.3 V)-ensures timing compliance in sub-10 ns critical paths |
| IOFF Leakage | ±5 μA max (VCC(A)=0 V or VCC(B)=0 V)-guarantees safe isolation during system sleep states |
| Bus Hold Current | ±100 μA min (at 3.0 V)-actively sustains logic state without pull resistors, saving PCB area and power |
| ESD Rating | HBM >8 kV, CDM >1 kV-meets industrial robustness requirements for handling and board-level stress |
| Operating Temp | -40 °C to +125 °C-qualified for automotive under-hood and industrial control applications |
Pinout & Package
XSON8 package (SOT1116), 1.2 × 1.0 × 0.35 mm, no leads, 8-terminal surface-mount design optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(B) | Supply rail for B-side I/O (1B, 2B); sets input thresholds and output swing for port B |
| 2 | 1B | B-side data I/O terminal; bidirectionally translated based on DIR state and VCC(B) |
| 3 | 2B | B-side data I/O terminal; electrically isolated from A-side except during active translation |
| 4 | DIR | Direction control input referenced to VCC(A); HIGH = A→B, LOW = B→A |
| 5 | 2A | A-side data I/O terminal; referenced to VCC(A); drives or receives signals at A-voltage domain |
| 6 | 1A | A-side data I/O terminal; shares same voltage reference and timing behavior as 2A |
| 7 | VCC(A) | Supply rail for A-side I/O (1A, 2A) and DIR input; defines A-port logic thresholds |
| 8 | GND | Common ground reference for both supply domains and internal logic; mandatory for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply translation | Independent VCC(A) and VCC(B) allow simultaneous operation at different voltages-enables heterogeneous SoC subsystem bridging |
| IOFF partial power-down | Outputs disable automatically if either VCC drops to GND-prevents back-current and supports dynamic power gating |
| Integrated bus hold | Eliminates need for external pull-up/down resistors on floating I/Os-reduces component count and layout area |
| Wide temperature range | Specified from -40 °C to +125 °C-suitable for automotive engine control units and industrial motor drives |
| High noise immunity | Low overshoot/undershoot (<10% of VCC) and strong ESD protection ensure reliable operation in noisy environments |

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 different IOFF threshold (VCC < 0.25 V) and higher max ICC (20 μA vs. 16 μA typical) | Qualified only to +85 °C; lacks bus hold-requires external pull resistors | Select when TI ecosystem integration or specific thermal derating rules apply |
| TXS0102DCUR | TI auto-direction-sensing variant; no DIR pin; higher propagation delay (15 ns typ.) | Unidirectional use cases only; unsuitable for controlled bidirectional protocols like SPI full-duplex | Choose only for simple push-pull GPIO translation where direction is software-managed externally |

FAQ
What is the minimum recommended supply voltage for reliable operation?
The 74AVCH2T45GN,115 is fully specified from 0.8 V to 3.6 V on both VCC(A) and VCC(B). At 0.8 V, it delivers VOH ≥ 0.69 V and VOL ≤ 0.07 V with 1.5 mA load, meeting JEDEC JESD8-12 compliance. Operation below 0.8 V is not characterized and may result in undefined logic thresholds or increased propagation delay.
Can the DIR pin be left unconnected or tied to VCC/GND through a weak resistor?
No-DIR must be actively driven to a valid logic level (HIGH or LOW) referenced to VCC(A). Floating DIR causes indeterminate direction control and potential bus contention. The device has no internal pull-up/pull-down on DIR; external 10 kΩ pull-up/down to VCC(A) is acceptable only if system timing allows static direction setting.
Does the bus hold feature work when one supply is powered down?
Yes-bus hold remains active on both A and B ports as long as its respective supply (VCC(A) or VCC(B)) is ≥ 0.8 V. When either supply drops to GND, that port enters high-impedance suspend mode and bus hold is disabled for that side only; the other port retains bus hold if its supply is active.
How does IOFF behave during power sequencing where VCC(A) ramps before VCC(B)?
IOFF activates only when either VCC(A) or VCC(B) reaches GND-not during ramp-up. During asymmetric power-on (e.g., VCC(A) applied before VCC(B)), the A-side I/Os remain functional while B-side outputs are in high-Z until VCC(B) stabilizes. No damaging current flows, and DIR remains valid once VCC(A) exceeds 0.8 V.
