Product details
Overview
NTB0104BQ,115 from NXP Semiconductors is a 4-bit dual-supply translating transceiver with auto-direction sensing and 3-state outputs, enabling bidirectional voltage level translation between 1.2 V–3.6 V (VCC(A)) and 1.65 V–5.5 V (VCC(B)) domains. It features independent A/B port referencing, IOFF partial power-down protection, and operates across –40 °C to +125 °C for automotive and industrial bus interfacing.
For engineers reviewing the NTB0104BQ,115 datasheet, NTB0104BQ,115 pinout, NTB0104BQ,115 application, or NTB0104BQ,115 equivalent, this device supports high-speed I²C, SPI, and GPIO bridging between mixed-voltage SoCs, microcontrollers, and peripheral ICs - with propagation delays as low as 0.8 ns (B-to-A, VCC(A)=3.3 V, VCC(B)=5.0 V) and data rates up to 100 Mbps under specified conditions.
Technical Context
The NTB0104BQ,115 implements edge-detecting one-shot circuitry on both A and B ports to autonomously enable direction-controlled output drivers without external control signals. Its weak-output architecture allows overdriving during bus contention, while internal PMOS/NMOS acceleration transistors reduce transition times - typical output impedance is 40 Ω at VCCO = 3.3–5.0 V, 50 Ω at 1.8–3.3 V, and 70 Ω at 1.2–1.8 V.
IOFF circuitry disables outputs and blocks damaging backflow current when either VCC(A) or VCC(B) is at GND, supporting hot-swap and partial power-down operation. Input clamping protects against overvoltage (VI up to 6.5 V), and ESD robustness exceeds 15 kV HBM on the B port per JESD22-A114E Class 3B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-port logic and OE input; enables interface with 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V systems |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-port logic; supports 1.8 V/2.5 V/3.3 V/5.0 V domains and legacy 5 V peripherals |
| Propagation Delay (B→A) | 0.8 ns min / 7.9 ns max - ensures sub-nanosecond timing margin for high-speed bidirectional buses like I²C Fast-mode Plus |
| Data Rate | Up to 100 Mbps - validated at VCC(A)=3.3 V, VCC(B)=5.0 V, Tamb=–40 °C to +125 °C |
| IOFF Leakage | ±2 μA max - prevents back-current flow during power sequencing or system sleep states |
| ESD (B Port) | >15 kV HBM - meets stringent industrial and automotive board-level ESD requirements per JESD22-A114E Class 3B |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive, motor control, and industrial PLC applications |
Pinout & Package
DHVQFN14 package (SOT762-1), 2.5 × 3.0 × 0.85 mm, thermal-enhanced no-lead quad flat; exposed die pad electrically isolated (GND not required).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC(A) | Supply for A-side logic and OE input; must be ≤ VCC(B) per spec |
| 2–5 | A1–A4 | Bidirectional I/O referenced to VCC(A); auto-sense direction via edge detection |
| 6, 9 | n.c. | No internal connection; no routing or soldering required |
| 7 | GND | Ground reference; substrate attached but electrically floating unless tied to system GND |
| 8 | OE | Active-HIGH output enable (referenced to VCC(A)); LOW forces all outputs to high-impedance |
| 10–13 | B1–B4 | Bidirectional I/O referenced to VCC(B); drives/receives at B-domain voltage levels |
| 14 | VCC(B) | Supply for B-side logic; supports up to 5.5 V for legacy 5 V interface compatibility |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates external direction-control logic; detects rising/falling edges on A/B ports to enable correct driver path |
| IOFF partial power-down | Blocks back-current when either supply is off - critical for safe hot-plug and multi-rail power sequencing |
| Wide VCC(A)/VCC(B) range | Enables single-device bridging across 1.2 V ↔ 5.0 V - covers all common logic families without discrete level shifters |
| High ESD robustness (B port) | 15 kV HBM rating reduces need for external TVS diodes in noisy industrial environments |
| Low propagation skew | 0.2 ns max output skew between channels - preserves timing integrity in parallel data paths (e.g., 4-bit GPIO banks) |

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 |
|---|---|---|---|
| TXS0104E | 4-bit, auto-direction, VCCA=1.2–3.6 V, VCCB=1.65–5.5 V; lacks IOFF and has higher VOL (0.75 V max @ 20 mA) | Not qualified for –40 °C to +125 °C; limited to commercial temp range (–40 °C to +85 °C) | Prefer NTB0104BQ,115 for extended temperature or safety-critical IOFF requirement |
| SN74AVC4T245 | 4-bit, direction-pin controlled (not auto-sensing); VCCA/VCCB=1.2–3.6 V; no 5 V tolerance on B port | Requires external direction control logic and cannot interface directly to 5 V peripherals | Choose NTB0104BQ,115 when eliminating direction pins and supporting 5 V B-side operation are mandatory |
Compared with TXS0104E and SN74AVC4T245, the NTB0104BQ,115 uniquely combines auto-direction sensing, 5 V-tolerant B-port inputs/outputs, IOFF protection, and full –40 °C to +125 °C qualification - making it the only option for robust, pin-minimized, mixed-voltage bridging in automotive and industrial control systems.

FAQ
What is the maximum allowable voltage on the B-port inputs of NTB0104BQ,115?
The B-port inputs of NTB0104BQ,115 accept voltages up to 5.5 V regardless of VCC(B) level, as confirmed in the Limiting Values table (VI max = +6.5 V absolute, but recommended operating VI max = 5.5 V). This enables direct interfacing with 5 V TTL and CMOS logic without external clamping, provided VCC(B) ≥ 1.65 V.
Does NTB0104BQ,115 require an external direction-control signal?
No. NTB0104BQ,115 uses internal edge-detection circuitry on both A and B ports to automatically sense data flow direction and enable the appropriate driver path. This eliminates the need for an external DIR pin or control logic, reducing PCB complexity and firmware overhead compared to direction-pin-based translators like SN74AVC4T245.
Can NTB0104BQ,115 operate with VCC(A) = 1.2 V and VCC(B) = 5.0 V simultaneously?
Yes. The NTB0104BQ,115 is fully specified for VCC(A) = 1.2 V to 3.6 V and VCC(B) = 1.65 V to 5.5 V concurrently. At these rails, it achieves 100 Mbps data rate and maintains IOFF protection - enabling direct bridging between ultra-low-power 1.2 V sensor nodes and legacy 5 V peripherals.
What is the purpose of the n.c. pins (6 and 9) on the DHVQFN14 package of NTB0104BQ,115?
Pins 6 and 9 on NTB0104BQ,115 are internally not connected. They serve no electrical function and require no routing or soldering. The datasheet explicitly states they are "not connected" and may be left unconnected or grounded for mechanical stability - but grounding does not affect device operation or performance.
How does the IOFF feature of NTB0104BQ,115 protect downstream circuitry during power-down?
When either VCC(A) or VCC(B) drops to GND, the IOFF circuitry in NTB0104BQ,115 disables all outputs and limits leakage current to ±2 μA max. This prevents damaging backflow current from a live rail into a powered-down domain - a critical safeguard during hot-swap events, battery disconnects, or staggered power sequencing in multi-rail systems.
