Product details
Overview
74AVCH2T45GS,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 protection, and integrated bus hold on all data pins. It supports up to 500 Mbps (1.8 V → 3.3 V) in high-speed interface bridging between mixed-voltage SoCs and peripherals.
For engineers reviewing the 74AVCH2T45GS,115 datasheet, 74AVCH2T45GS,115 pinout, 74AVCH2T45GS,115 application, or 74AVCH2T45GS,115 equivalent, this device is selected for low-voltage bidirectional translation in space-constrained embedded systems where supply independence, suspend-mode robustness, and elimination of external pull resistors are critical design requirements.
Technical Context
The 74AVCH2T45GS operates as a direction-controlled, dual-rail transceiver with independent VCC(A) and VCC(B) supplies (0.8 V–3.6 V each). DIR input-referenced solely to VCC(A)-determines signal flow: HIGH enables A→B translation, LOW enables B→A. Its IOFF circuit disables outputs when either supply is at GND, preventing backflow current during partial power-down.
Active bus hold circuitry maintains valid logic states on floating 1A/2A/1B/2B inputs without external resistors. Propagation delays range from 0.5 ns (3.3 V ↔ 3.3 V) to 9.9 ns (0.8 V ↔ 1.2 V) across temperature (−40 °C to +125 °C) and voltage combinations, with disable/enable times tightly bounded per JEDEC-compliant test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | VCC(A) and VCC(B): 0.8 V to 3.6 V - enables translation across 0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| Max Data Rate | 500 Mbps (1.8 V → 3.3 V) - supports high-speed interconnects like GPIO expansion and low-latency sensor interfaces |
| Propagation Delay | 0.5 ns to 9.9 ns (−40 °C to +125 °C) - ensures timing predictability in real-time control loops and synchronous buses |
| IOFF Leakage | ±5 μA max (VCC = 0 V) - guarantees safe hot-swap and partial power-down operation without damaging back-current |
| Bus Hold Current | ±100 μA (3.0 V), ±45 μA (2.3 V) - actively sustains valid logic levels on unused pins, removing need for 10 kΩ pull resistors |
| ESD Protection | HBM > 8000 V, CDM > 1000 V - meets industrial-grade robustness for handling and board-level ESD events |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and wide-temperature IoT edge nodes |
Pinout & Package
XSON8 package (SOT1203): extremely thin small outline, no leads, 1.35 mm × 1.0 mm × 0.35 mm body, 8-terminal surface-mount footprint optimized for high-density PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 2B | Data I/O port B (bidirectional, referenced to VCC(B)) - connects to 0.8–3.6 V domain B signals |
| 2 | 1B | Data I/O port B (bidirectional, referenced to VCC(B)) - second channel for B-side interface |
| 3 | VCC(B) | Supply for port B - sets logic thresholds and output drive strength for B-side pins |
| 4 | DIR | Direction control input (referenced to VCC(A)) - HIGH = A→B, LOW = B→A; no internal pull |
| 5 | 2A | Data I/O port A (bidirectional, referenced to VCC(A)) - connects to 0.8–3.6 V domain A signals |
| 6 | 1A | Data I/O port A (bidirectional, referenced to VCC(A)) - second channel for A-side interface |
| 7 | VCC(A) | Supply for port A - sets logic thresholds and output drive strength for A-side pins |
| 8 | GND | Common reference ground - must be connected before any supply; required for IOFF and bus hold functionality |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) operate independently from 0.8 V to 3.6 V - eliminates need for level-shifting LDOs or charge pumps |
| IOFF partial power-down | Outputs disable automatically when either VCC drops to GND - prevents back-driving and latch-up in powered-down subsystems |
| Integrated bus hold | Eliminates external pull-up/pull-down resistors on 1A/2A/1B/2B - reduces BOM count and PCB area in GPIO-expansion designs |
| Suspend mode | Both ports enter high-impedance OFF-state if VCC(A) = GND or VCC(B) = GND - ensures clean isolation during sleep or fault recovery |
| JEDEC-compliant voltage standards | Meets JESD8-12 through JESD8-B across full voltage range - guarantees interoperability with JEDEC-defined memory, MCU, and FPGA I/O |

FAQ
What is the minimum recommended supply voltage for reliable bus hold operation?
Bus hold functionality is fully specified from VCC(A) = VCC(B) = 0.8 V. At 0.8 V, IBHL and IBHH are guaranteed ≥ ±26 μA per I/O pin, sufficient to maintain valid logic states against typical PCB leakage and noise. Operation below 0.8 V is not characterized and may result in undefined hold strength or increased susceptibility to noise-induced glitches.
Can DIR be driven from a 3.3 V source when VCC(A) is 1.2 V?
No. DIR is strictly referenced to VCC(A); its VIH min is 0.65 × VCC(A) and VIL max is 0.35 × VCC(A). With VCC(A) = 1.2 V, VIH min = 0.78 V - a 3.3 V signal would exceed the absolute maximum input voltage rating (VCC(A) + 0.5 V = 1.7 V) and risk permanent damage. A level-shifter or resistor divider is required for such cross-rail control.
How does IOFF behave when only VCC(B) is powered?
When VCC(B) = 0 V and VCC(A) = 0.8–3.6 V, the B-port outputs (1B, 2B) enter high-impedance OFF-state with IOFF leakage ≤ ±5 μA. The A-port remains functional, but B-port inputs become invalid. This allows safe isolation of the B-side bus while keeping A-side logic active - critical for modular subsystem power management.
Is the 74AVCH2T45GS,115 compatible with I²C open-drain signaling?
No. The 74AVCH2T45GS,115 is a push-pull transceiver with no built-in open-drain emulation or slew-rate control. Its outputs actively drive HIGH and LOW, which conflicts with I²C bus arbitration. For I²C level shifting, dedicated devices like the NX3P2212 or PCA9306 are required.
