Product details
Overview
74LVC1T45GN,132 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 data direction (A↔B), IOFF-enabled partial power-down, and operates from −40 °C to +125 °C in the ultra-compact XSON6 (SOT1115) package.
For engineers reviewing the 74LVC1T45GN,132 datasheet, 74LVC1T45GN,132 pinout, 74LVC1T45GN,132 application, or 74LVC1T45GN,132 equivalent, this device is selected for low-voltage I/O bridging in mixed-rail SoC interfaces, FPGA-to-ASIC voltage domain isolation, and battery-powered sensor hub interconnects where leakage control and suspend-mode integrity are critical.
Technical Context
The 74LVC1T45GN implements a dual-rail CMOS transceiver architecture with separate input-referenced logic domains: A port and DIR are referenced to VCC(A); B port is referenced to VCC(B). Direction control is synchronous and non-latched - DIR HIGH enables A→B transmission; DIR LOW enables B→A transmission.
Its IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is at GND, forcing both ports into high-impedance OFF-state to prevent backflow current. The 74LVCH1T45 variant adds active bus hold on A/B ports; the 74LVC1T45GN does not include bus hold, confirmed by absence in static characteristics tables and footnote [4] specifying "non bus hold parts only".
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 5.5 V - supports direct interface to 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic domains |
| VCC(B) Range | 1.2 V to 5.5 V - independent supply allows asymmetric rail translation (e.g., 1.8 V ↔ 3.3 V) |
| Max Data Rate | 420 Mbps (3.3 V → 5.0 V) - defines maximum usable frequency for high-speed digital bridging |
| IOFF Leakage | ±2 μA max at −40 °C to +125 °C - ensures safe hot-insertion and power sequencing in multi-rail systems |
| Propagation Delay | 1.4 ns to 48.6 ns (A↔B, DIR-controlled) - delay varies with VCC pair and temperature; worst-case tPZH = 48.6 ns at 1.5 V/−40 °C |
| Supply Current | 16 μA max ICC (A+B) - ultra-low static power enables always-on bridge operation in energy-constrained designs |
| ESD Rating | HBM >4000 V, CDM >1000 V - meets industrial-grade robustness requirements without external protection |
Pinout & Package
The 74LVC1T45GN is housed in an XSON6 package (SOT1115): 0.9 mm × 1.0 mm × 0.35 mm body, no leads, 6 terminals, wettable flank option available. Pin 1 indicator is located on lower left corner below marking code "V5".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for port A and DIR input - all A-side logic thresholds and drive strength scale with this rail |
| 2 | GND | Common reference for both domains - required for signal return and IOFF functionality |
| 3 | A | Bidirectional data terminal referenced to VCC(A) - functions as input or output depending on DIR state |
| 4 | B | Bidirectional data terminal referenced to VCC(B) - isolated voltage domain enables level translation |
| 5 | DIR | Direction control input referenced to VCC(A) - HIGH = A→B, LOW = B→A; edge-triggered behavior not supported |
| 6 | VCC(B) | Supply for port B - independent of VCC(A), enabling true dual-voltage operation |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent supply rails | VCC(A) and VCC(B) each support 1.2 V–5.5 V - eliminates need for external level shifters in mixed-voltage PCBs |
| IOFF partial power-down | Outputs disable automatically if either VCC drops to GND - prevents back-current damage during power sequencing or hot-swap |
| 3-state output control | DIR-driven bidirectional enable/disable - no separate OE pin required; simplifies control logic |
| Wide temperature range | Specified from −40 °C to +125 °C - qualified for automotive under-hood, industrial motor control, and telecom infrastructure |
| Ultra-small footprint | SOT1115 (0.9 × 1.0 mm) - saves board space in portable, wearable, and dense module designs |
Applications
| Industrial PLC I/O Module | FPGA-to-Microcontroller Interface |

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 |
|---|---|---|---|
| SN74LVC1T45DCKR | TI part in SC-70-6 package; identical functional spec but different pinout (VCC(A)/GND/A/B/DIR/VCC(B) vs. 74LVC1T45GN's VCC(A)/GND/A/B/DIR/VCC(B) order differs in physical layout) | SC-70-6 (2.0 × 1.25 mm) is 2.2× larger than SOT1115; lacks wettable flanks for automated optical inspection | Select when board layout accommodates larger footprint and TI supply chain preference applies |
| 74LVCH1T45GN,132 | Same Nexperia XSON6 package and pinout, but includes active bus hold on A/B ports (IBHL/IBHH up to ±100 μA); higher ICC (max 8 μA vs. 16 μA) | Bus hold eliminates need for external pull-ups on floating I/Os - beneficial in systems with unconnected test points or intermittent connections | Select when unused or intermittently connected data lines require deterministic logic levels without external resistors |
Compared with SN74LVC1T45DCKR, the 74LVC1T45GN offers 55 % smaller footprint and wettable flanks for solder joint inspection; compared with 74LVCH1T45GN, it trades bus hold capability for lower static current and reduced input capacitance - critical for high-speed, low-power sensor interfaces.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
VCC(A) and VCC(B) may differ by up to 4.3 V (e.g., 1.2 V and 5.5 V simultaneously), as both rails are independently rated from −0.5 V to +6.5 V per absolute maximum ratings. No internal clamping exists between supplies, so external decoupling must be applied per rail.
Does the 74LVC1T45GN support hot-swap or live insertion?
Yes - its IOFF circuitry ensures outputs enter high-impedance state when either VCC(A) or VCC(B) is at GND, preventing back-current flow during live insertion. This is validated per JESD78 Class II latch-up testing (>100 mA) and specified for partial power-down operation.
Can DIR be driven from a different voltage domain than VCC(A)?
No - DIR is strictly referenced to VCC(A); applying voltage outside 0 V to VCC(A) violates absolute maximum ratings and risks damage. Level-shifting DIR requires a dedicated buffer referenced to VCC(A), such as a 74LVC1G17.
Is there a version with integrated ESD protection beyond HBM 4000 V?
No - the 74LVC1T45GN provides HBM >4000 V and CDM >1000 V per JEDEC JS-001/JS-002, meeting standard industrial ESD requirements. For enhanced protection (e.g., IEC 61000-4-2), external TVS diodes on A/B lines are recommended.
