Product details
Overview
NTB0101GF,132 from NXP Semiconductors is a 1-bit dual-supply auto-direction-sensing voltage-level translating transceiver enabling bidirectional translation between 1.2 V–3.6 V (VCC(A)) and 1.65 V–5.5 V (VCC(B)) domains. It features A/B I/O ports referenced to separate supplies, active-HIGH OE control, IOFF partial power-down protection, and operates across −40 °C to +125 °C. Used in mixed-voltage interfaces like 1.8 V MCU to 3.3 V peripheral interconnects.
For engineers reviewing the NTB0101GF,132 datasheet, NTB0101GF,132 pinout, NTB0101GF,132 application, or NTB0101GF,132 equivalent, key selection criteria include guaranteed 40 Mbps data rate at −40 °C to +125 °C, 7.5 pF B-port input/output capacitance, IOFF-enabled backflow current prevention, and compatibility with 1.0 × 1.0 × 0.5 mm XSON6 (SOT891) packaging.
Technical Context
The NTB0101GF,132 implements auto-direction sensing via edge-triggered one-shot circuits that dynamically enable PMOS/NMOS boost transistors during signal transitions-accelerating rise/fall times without external direction control. Its dual-rail architecture isolates A-side (VCC(A)-referenced) and B-side (VCC(B)-referenced) logic domains while maintaining bidirectional signal flow through weak-output drivers capable of being overdriven.
IOFF circuitry actively disables outputs when either supply is at GND, clamping leakage to ±10 µA across −40 °C to +125 °C. Input tolerance up to 5.5 V on both A and B ports allows safe interfacing with higher-voltage systems even when VCC(A) is as low as 1.2 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - supports 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V logic domains |
| VCC(B) Range | 1.65 V to 5.5 V - enables translation to 1.8 V/2.5 V/3.3 V/5.0 V systems |
| Data Rate | Up to 100 Mbps at 3.3 V/5.0 V and 25 °C; 40 Mbps guaranteed over −40 °C to +125 °C |
| Propagation Delay | A→B: 0.8–15.9 ns; B→A: 0.3–17.2 ns - varies with supply voltage and temperature |
| IOFF Leakage | ±10 µA max at −40 °C to +125 °C - prevents damaging backflow during partial power-down |
| ESD Rating | B port: HBM Class 3B >15 kV; A port: HBM Class 2 >2.5 kV - robust system-level ESD immunity |
| Operating Temp | −40 °C to +125 °C - qualified for automotive and industrial under-hood applications |
Pinout & Package
NTB0101GF,132 is housed in a 1.0 × 1.0 × 0.5 mm plastic XSON6 package (SOT891), leadless, with exposed die pad for thermal performance. Pin 1 indicator located on lower-left corner below marking code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply for A-side logic | References A port and OE input; must be ≤ VCC(B) in active operation |
| GND | Common ground reference | Shared return path for both supply domains; required for IOFF and ESD clamp operation |
| A | Bidirectional I/O (A-side) | Signal terminal referenced to VCC(A); accepts inputs up to 5.5 V regardless of VCC(A) |
| B | Bidirectional I/O (B-side) | Signal terminal referenced to VCC(B); supports 5.5 V tolerant inputs and outputs |
| OE | Output enable (active HIGH) | Referenced to VCC(A); LOW forces high-impedance OFF-state on both A and B ports |
| VCC(B) | Supply for B-side logic | References B port; enables translation to 5.0 V systems when VCC(A) = 1.2 V |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates external direction-control signals and simplifies PCB routing in bidirectional buses |
| IOFF partial power-down | Prevents destructive back-current when either VCC(A) or VCC(B) is unpowered |
| 5.5 V-tolerant I/O | Allows safe connection to 5 V systems even when VCC(A) = 1.2 V, avoiding level-shifter cascades |
| Low dynamic power | CPD as low as 0.01 pF in 3-state mode reduces switching noise and system power consumption |
| High-temp reliability | Specified for full functionality at −40 °C to +125 °C, meeting AEC-Q100 stress test requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCUR | Single-channel, auto-direction, 1.65–5.5 V I/O range; no VCC(A)/VCC(B) separation - single supply only | Lacks independent dual-supply rails; unsuitable for asymmetric voltage translation (e.g., 1.2 V ↔ 5.0 V) | Select NTB0101GF,132 when independent A/B supply control and 1.2 V compatibility are required. |
| SN74AVC1T45DBVR | Direction-controlled (DIR pin required); supports 1.2–3.6 V I/O; no IOFF; smaller 1.45 × 1.0 mm XSON6 (SOT886) | Requires external direction signal; no partial power-down protection; lower ESD rating (HBM 2 kV) | Choose NTB0101GF,132 for hands-off bidirectional operation and robust IOFF in hot-swap or sleep-mode systems. |
Compared with TXS0101DCUR and SN74AVC1T45DBVR, NTB0101GF,132 uniquely supports true asymmetric dual-supply translation down to 1.2 V on A-side while delivering IOFF protection and >15 kV HBM on the B port-critical for automotive and industrial mixed-voltage subsystems.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for NTB0101GF,132?
The NTB0101GF,132 requires VCC(A) ≤ VCC(B) during active operation per datasheet Section 12.4. While absolute maximum ratings allow both supplies up to +6.5 V individually, sustained operation with VCC(A) > VCC(B) may cause undefined behavior or accelerated wear. The device tolerates transient VCC(A) ≥ VCC(B) during power-up without damage.
Does NTB0101GF,132 support I²C or 1-Wire bus protocols?
No - NTB0101GF,132 is not recommended for I²C or 1-Wire due to its weak static drive strength (designed for capacitive loads ≤70 pF) and lack of open-drain output structure. Pull-up resistors <50 kΩ cause contention. For I²C, NXP recommends the NTS0101; for 1-Wire, dedicated bidirectional open-drain translators are required.
How does the auto-direction sensing work in NTB0101GF,132 without a DIR pin?
NTB0101GF,132 uses internal edge-detecting one-shot circuits on both A and B ports. When a rising or falling edge occurs, it briefly activates PMOS or NMOS boost transistors to accelerate transitions - enabling automatic direction detection without external control. This architecture relies on weak output drivers that yield to stronger external drivers during reverse-flow events.
What is the disable time (tdis) for NTB0101GF,132 when OE goes LOW?
For NTB0101GF,132, tdis (OE to A/B disable) is 1.0–12.5 ns depending on VCC(B) and temperature. At VCC(B) = 5.0 V and −40 °C to +125 °C, maximum tdis is 12.5 ns (Table 12). With no external load, this is the delay between OE transitioning LOW and A/B outputs entering high-impedance state.
Can NTB0101GF,132 be used with VCC(A) = 1.2 V and VCC(B) = 5.0 V simultaneously?
Yes - NTB0101GF,132 is explicitly rated for VCC(A) = 1.2 V to 3.6 V and VCC(B) = 1.65 V to 5.5 V concurrently. At this combination, it delivers 4.2 ns typical propagation delay (A→B) and 4.4 ns (B→A) at 25 °C, with guaranteed 40 Mbps data rate across −40 °C to +125 °C per Table 11 and Table 12.
