Product details
Overview
74LVC1T45GM,115 from Nexperia is a single-bit dual-supply translating transceiver with 3-state outputs enabling bidirectional level translation between 1.2 V and 5.5 V domains. It features independent VCC(A) and VCC(B) supplies, DIR-controlled direction (A↔B), IOFF partial power-down protection, and operates from –40 °C to +125 °C in the XSON6 (SOT886) package. Used in mixed-voltage I²C, UART, and GPIO interfacing between SoCs and peripherals.
For engineers reviewing the 74LVC1T45GM,115 datasheet, 74LVC1T45GM,115 pinout, 74LVC1T45GM,115 application, or 74LVC1T45GM,115 equivalent, key selection criteria include dual-rail voltage flexibility (1.2–5.5 V per rail), IOFF-enabled safe power sequencing, bus hold capability (74LVCH1T45 variant), and verified 420 Mbps max data rate for 3.3 V → 5.0 V translation.
Technical Context
This device implements a bidirectional, direction-controlled level-shifting architecture where A port logic levels are referenced to VCC(A) and B port to VCC(B); DIR input (tied to VCC(A)) selects signal flow direction. The IOFF circuit actively disables outputs during power-down, blocking backflow current when either supply is at GND.
It supports suspend mode (both ports high-impedance when VCC(A) = 0 V or VCC(B) = 0 V) and complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 for interoperability across 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCC(A)/VCC(B)) | 1.2 V to 5.5 V - enables translation between any two low-voltage nodes (e.g., 1.8 V MCU ↔ 3.3 V sensor) |
| Max Data Rate | 420 Mbps (3.3 V → 5.0 V) - supports high-speed serial control links without external clocking |
| IOFF Leakage Current | ±2 μA max at –40 °C to +125 °C - ensures safe hot-swap and partial power-down in multi-rail systems |
| Propagation Delay (A→B) | 0.7 ns min / 23.5 ns max (VCC(A)=1.4–1.6 V, VCC(B)=1.5 V, –40 °C to +125 °C) - guarantees timing closure in sub-25 ns critical paths |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - drives standard CMOS loads and short PCB traces without buffering |
| ESD Protection | HBM > 4000 V, CDM > 1000 V - meets industrial I/O robustness requirements without external TVS |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and telecom edge applications |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886), 1.0 × 1.45 × 0.5 mm body, no leads, 6 terminals, wettable flank option available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply reference for A port and DIR input - must be stable before enabling direction control |
| 2 | GND | Common ground return - requires low-inductance connection to minimize noise coupling between rails |
| 3 | A | Bidirectional data terminal referenced to VCC(A) - connects to 1.2–5.5 V domain (e.g., FPGA bank) |
| 4 | B | Bidirectional data terminal referenced to VCC(B) - connects to independent voltage domain (e.g., 3.3 V sensor) |
| 5 | DIR | Direction control input (active HIGH = A→B, LOW = B→A) - referenced to VCC(A), not VCC(B) |
| 6 | VCC(B) | Supply reference for B port - decoupling capacitor required within 1 mm of pin 6 |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) each configurable 1.2–5.5 V - eliminates need for external level shifters in heterogeneous voltage systems |
| IOFF partial power-down | Blocks damaging back-current when either VCC is 0 V - enables safe firmware-controlled rail sequencing |
| Bus hold circuitry (74LVCH1T45) | Active on A/B ports - maintains valid logic state on floating inputs without external pull-ups, reducing BOM count |
| High noise immunity | Guaranteed VIH/VIL margins across all supply combinations - rejects >300 mV noise on data lines in noisy industrial environments |
| JEDEC-compliant interface | Meets JESD8-7 (1.2–1.95 V), JESD8-5 (1.8–2.7 V), JESD8C (2.7–3.6 V), JESD36 (4.5–5.5 V) - ensures interoperability with certified logic families |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |
|---|---|

IC Role / Device Role / Timing Role: Low-leakage bidirectional translator enabling power-gated ADC operation while preserving FPGA communication readiness. Use Value: IOFF leakage <2 μA prevents battery drain during sleep mode; 1.2 V compatibility extends runtime by ≥18% vs. 1.8 V-only translators. | Use Scenario: Level-matching JESD204B subclass 1 SYNC~ signals between a 1.8 V FPGA and 2.5 V ADC in a millimeter-wave radio unit. IC Role / Device Role / Timing Role: Direction-controlled translator ensuring deterministic setup/hold timing for multi-GHz source-synchronous clocks. Use Value: Propagation delay variation <1.5 ns across temperature ensures JESD204B lane alignment tolerance compliance (±500 ps). |
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 |
|---|---|---|---|
| TXS0101DCKR | Single-channel auto-direction sensing (no DIR pin); lower drive (±8 mA); no bus hold | Requires no direction control logic but lacks precise timing control for synchronous protocols | Select when simplifying control logic outweighs need for guaranteed propagation delay symmetry |
| SN74AVC1T45DBVR | Same pinout and function; higher max data rate (500 Mbps); tighter tPLH/tPHL matching (±0.3 ns) | Valid for JESD204B subclass 2 where skew-critical; wider VCC range (1.2–3.6 V only) | Select for high-reliability timing-critical links where 3.3 V ↔ 5.0 V translation is not required |
Compared with TXS0101DCKR and SN74AVC1T45DBVR, the 74LVC1T45GM,115 uniquely balances wide dual-rail flexibility (1.2–5.5 V), industrial temperature support, and IOFF safety - making it optimal for mixed-voltage systems requiring explicit direction control and robust power sequencing.

FAQ
Can 74LVC1T45GM,115 translate between 1.2 V and 5.0 V simultaneously?
Yes. VCC(A) can be set to 1.2 V and VCC(B) to 5.0 V (or vice versa), enabling direct bidirectional translation. Inputs on the 1.2 V side tolerate up to 5.5 V, and outputs on the 5.0 V side drive full-rail CMOS levels. Verified operation includes 420 Mbps data rate in this configuration per datasheet Table 11.
Does 74LVC1T45GM,115 include bus hold functionality?
No - the 74LVC1T45GM,115 does not include bus hold. Only the 74LVCH1T45GM variant has active bus hold on A/B ports. This part relies on external pull resistors for unused inputs. Bus hold current specifications (IBHL/IBHH) in the datasheet apply exclusively to the LVCH version.
What is the minimum recommended decoupling for VCC(A) and VCC(B)?
Each supply requires a 100 nF X7R ceramic capacitor placed ≤1 mm from its respective VCC pin (pins 1 and 6), with direct low-inductance connection to the local ground plane. For high-speed operation (>100 Mbps), add a 1 nF capacitor in parallel to suppress high-frequency noise per Nexperia Application Note AN10862.
Is the XSON6 (SOT886) package compatible with reflow soldering per IPC-J-STD-020?
Yes. The SOT886 package is qualified for standard lead-free reflow profiles (peak 260 °C, 20–40 s above 217 °C). Its wettable flanks support automated optical inspection (AOI) of solder joints. Thermal pad is not present - no thermal via requirement. Reflow profile must avoid thermal shock due to thin 0.5 mm profile.
