Product details
Overview
NTB0104BQ-Q100 from NXP Semiconductors is an automotive-qualified 4-bit dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and 3-state outputs. It enables seamless interfacing between 1.2 V–3.6 V (A-side) and 1.65 V–5.5 V (B-side) domains, supports ±2 mA input drive, features IOFF partial power-down protection, and operates across −40 °C to +125 °C for engine control and ADAS sensor interfaces.
For engineers reviewing the NTB0104BQ-Q100 datasheet, NTB0104BQ-Q100 pinout, NTB0104BQ-Q100 application, or NTB0104BQ-Q100 equivalent, key selection criteria include its asymmetric supply range compatibility, A/B port ESD robustness (15 kV HBM on B-port), propagation delay ≤7.7 ns (A→B at 3.3 V/5.0 V), and DHVQFN14 thermal-enhanced package suitability for space-constrained automotive PCBs.
Technical Context
The NTB0104BQ-Q100 implements auto-direction sensing via edge-triggered one-shot circuits that dynamically enable PMOS/NMOS boost transistors during signal transitions-eliminating external direction control. Its I/O architecture maintains defined static output levels while allowing external drivers to overdrive outputs during bus contention, with typical output impedance of 40 Ω at VCC(B) = 3.3–5.0 V.
IOFF circuitry ensures safe partial power-down by disabling outputs and blocking backflow current when either VCC(A) or VCC(B) is at GND. The device requires no power-up sequencing: VCC(A) may ramp before or after VCC(B), and OE must be pulled low via resistor during power transitions to guarantee high-impedance state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCC(A)) | 1.2 V to 3.6 V - supports interface with ultra-low-voltage logic (1.2 V/1.5 V/1.8 V) without level-shifter biasing complexity |
| Supply Range (VCC(B)) | 1.65 V to 5.5 V - enables direct connection to legacy 3.3 V and 5.0 V microcontrollers or sensors |
| Propagation Delay (A→B) | ≤7.7 ns at VCC(A)=3.3 V, VCC(B)=5.0 V - ensures <10 ns timing margin for 80 Mbps data rates in CAN FD or LIN gateway applications |
| ESD Robustness (B-port) | 15 kV HBM - protects against electrostatic discharge in exposed automotive harness interfaces |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood engine control units and radar modules |
| IOFF Leakage Current | ±10 µA max at −40 °C to +125 °C - prevents damaging backflow during partial power-down in battery management systems |
| Input Drive Requirement | ±2 mA minimum - mandates compatible driver strength to reliably trigger auto-direction detection |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 mm × 3.0 mm × 0.85 mm body, thermally enhanced, leadless, with exposed die pad (non-soldered or floating/GND-connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | A-side supply reference | Power domain for An pins and OE; sets input threshold (VIH/VIL ≈ 0.65/0.35×VCC(A)) and defines A-port output swing |
| A1–A4 | A-side bidirectional I/O | 4-bit data path referenced to VCC(A); auto-senses direction based on edge transitions; tolerates inputs up to 5.5 V |
| OE | Output enable (active HIGH) | Referenced to VCC(A); LOW forces all ports into high-impedance OFF-state; pull-down required during power-up |
| GND | Ground reference | Common return for both supply domains; critical for noise immunity and ESD current path integrity |
| B1–B4 | B-side bidirectional I/O | 4-bit data path referenced to VCC(B); handles higher-voltage domains; 15 kV HBM ESD rating |
| VCC(B) | B-side supply reference | Power domain for Bn pins; sets B-port output swing and determines output impedance (40 Ω at 5.0 V) |

FAQ
What is the maximum data rate supported by the NTB0104BQ-Q100?
The NTB0104BQ-Q100 supports up to 100 Mbps data rate at VCC(A) = 3.3 V and VCC(B) = 5.0 V within −40 °C to +125 °C, verified by fdata testing in Table 12. This enables reliable use in high-speed LIN gateway bursts and SPI-based sensor interfaces where timing margins must accommodate worst-case propagation skew (≤0.5 ns) and transition times (≤4.7 ns on B-port).
Can NTB0104BQ-Q100 translate between 1.2 V and 5.0 V domains?
Yes, NTB0104BQ-Q100 explicitly supports VCC(A) = 1.2 V to 3.6 V and VCC(B) = 1.65 V to 5.5 V per Table 6, making 1.2 V ↔ 5.0 V translation fully valid. The device maintains specified VOH/VOL (e.g., VOH ≥ VCCO − 0.4 V) and propagation delay (≤12.9 ns A→B at 1.2 V/5.0 V, −40 °C to +125 °C) across this full range.
Is external direction control required for NTB0104BQ-Q100 operation?
No, NTB0104BQ-Q100 uses internal edge-detecting one-shot circuits to automatically sense data flow direction-no DIR pin or external logic is needed. As described in Section 13.2, rising/falling edges on A or B ports trigger transient PMOS/NMOS boost transistors, enabling true bidirectional operation with zero configuration overhead.
How does the IOFF feature protect the NTB0104BQ-Q100 during partial power-down?
The IOFF circuitry disables all outputs and blocks damaging backflow current when either VCC(A) or VCC(B) is at GND, as confirmed in Section 1. The power-off leakage current remains ≤±10 µA (Table 9) across −40 °C to +125 °C, ensuring safe operation during battery disconnect events or module sleep modes in automotive body controllers.
What is the recommended pull-down resistor value for OE on NTB0104BQ-Q100?
Per Section 13.5, OE must be tied to GND through a pull-down resistor during power-up/down to ensure high-impedance state. The minimum value depends on the driver's current-sourcing capability; for a typical 2 mA driver, R ≤ 1.7 kΩ (VCC(A)/2 mA) ensures OE remains below VIL (≤0.35×VCC(A)). Values between 1 kΩ and 10 kΩ are commonly used in automotive designs.
