Product details
Overview
NTB0102DP-Q100H from NXP Semiconductors is an automotive-qualified dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and 3-state output control. It supports 2-bit translation between 1.2 V–3.6 V (VCC(A)) and 1.65 V–5.5 V (VCC(B)), enables seamless interfacing between mixed-voltage domains such as 1.8 V microcontrollers and 3.3 V peripherals, and features IOFF circuitry for partial power-down protection.
For engineers reviewing the NTB0102DP-Q100H datasheet, NTB0102DP-Q100H pinout, NTB0102DP-Q100H application, or NTB0102DP-Q100H equivalent, this device is critical for automotive infotainment, ADAS sensor hubs, and body control modules requiring robust, AEC-Q100 Grade 1–compliant level shifting without external direction control logic.
Technical Context
The NTB0102DP-Q100H implements auto-direction sensing via edge-detecting one-shot circuits that dynamically enable PMOS/NMOS drivers during signal transitions-eliminating need for external DIR control. Its I/O cells deliver low-output-impedance drive (40–70 Ω depending on VCCO) while maintaining weak static drive to allow bus contention resolution.
IOFF circuitry ensures safe operation during partial power-down: when either VCC(A) or VCC(B) drops to GND, outputs are disabled to prevent backflow current. The device operates across –40 °C to +125 °C and enforces VCC(A) ≤ VCC(B) in active mode per design specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-side I/Os and OE; sets logic threshold for A-port signals. |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-side I/Os; enables translation to legacy 5 V systems. |
| Propagation Delay (A→B) | 0.8 ns (min) to 15.9 ns (max) - supports data rates up to 100 Mbps at 3.3 V/5.0 V supplies. |
| IOFF Leakage Current | ±2 μA max at –40 °C to +125 °C - prevents damaging backflow during asymmetric power-down. |
| ESD Protection (B port) | HBM Class 3B (>15 kV) - ensures robustness against handling and system-level ESD events in automotive harnesses. |
| Operating Temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin ECUs. |
| Input Capacitance (OE) | 1.0 pF typical - minimizes loading on control lines and preserves timing integrity in high-speed enable paths. |
Pinout & Package
TSSOP8 package (SOT505-2), 3 mm body width, 0.65 mm pitch, lead length 0.5 mm - compatible with standard surface-mount assembly and automotive PCB thickness requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2 | Data I/O (VCC(A)-referenced) | Bidirectional A-side ports; auto-sense direction via internal edge detection; tolerate up to 5.5 V inputs. |
| B1, B2 | Data I/O (VCC(B)-referenced) | Bidirectional B-side ports; drive strength scales with VCC(B); support 5 V-tolerant signaling. |
| OE | Output Enable (active HIGH, VCC(A)-referenced) | Asserting LOW forces all I/Os into high-impedance OFF-state; tdis ≤ 340 ns ensures fast isolation. |
| VCC(A) | Supply A | Power rail for A-side logic and OE input; must be ≤ VCC(B) during active operation. |
| VCC(B) | Supply B | Power rail for B-side logic and drivers; enables translation to higher-voltage domains. |
| GND | Ground Reference | Common return path for both supply domains; required for proper IOFF and ESD clamp operation. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates external DIR control line and associated routing complexity in space-constrained automotive PCBs. |
| IOFF partial power-down | Prevents destructive back-current flow when one supply is powered off-critical for domain-isolated vehicle networks. |
| Asymmetric supply flexibility | Supports 1.2 V ↔ 5.0 V translation (e.g., LPDDR I/O to legacy CAN transceivers) without external biasing. |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from –40 °C to +125 °C-meets stringent thermal reliability for engine bay modules. |
| High-speed dynamic performance | 100 Mbps data rate capability with <0.5 ns output skew ensures timing-critical serial links (e.g., SENT, PSI5) remain synchronized. |

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 |
|---|---|---|---|
| NTS0102DP-Q100 | Open-drain architecture with pull-up resistors; no auto-direction sensing; lower drive strength. | Targeted at I²C/SMBus interfaces only; unsuitable for push-pull buses like SPI or parallel data. | Select when protocol mandates open-drain topology and direction control is managed externally. |
| TXS0102QPWRQ1 | TI device with similar auto-direction and IOFF; wider VCC(A) range (1.65–3.6 V); no 1.2 V support. | Lacks 1.2 V compatibility-cannot interface with sub-1.5 V logic such as LPDDR4 I/O or advanced ASIL-B MCUs. | Choose only if system uses ≥1.65 V A-side supplies and TI ecosystem alignment is prioritized. |
Compared with NTS0102DP-Q100 and TXS0102QPWRQ1, the NTB0102DP-Q100H uniquely supports 1.2 V A-side operation and delivers higher drive strength for push-pull buses-making it the sole option for next-generation low-voltage automotive SoCs interfacing to legacy 5 V subsystems.

FAQ
What is the maximum data rate supported by the NTB0102DP-Q100H?
The NTB0102DP-Q100H supports up to 100 Mbps under recommended operating conditions (VCC(A) = 3.3 V, VCC(B) = 5.0 V, Tamb = –40 °C to +125 °C). This is validated by minimum pulse width (tW) of 10 ns and propagation delay (tpd) as low as 0.8 ns in A→B direction-enabling reliable use in high-speed serial links like SENT and PSI5 within automotive ECUs.
Can NTB0102DP-Q100H translate between 1.2 V and 5.0 V domains?
Yes-the NTB0102DP-Q100H explicitly supports VCC(A) from 1.2 V to 3.6 V and VCC(B) from 1.65 V to 5.5 V. Its inputs tolerate up to 5.5 V regardless of supply, and its auto-direction sensing operates correctly across this full range, making it suitable for interfacing ultra-low-power 1.2 V sensor nodes to 5 V legacy actuators in automotive systems.
Is NTB0102DP-Q100H pin-compatible with other NXP level translators?
No-NTB0102DP-Q100H uses the TSSOP8 (SOT505-2) package with a fixed 8-pin pinout optimized for dual-supply auto-direction operation. It is not pin-compatible with NTS0102DP-Q100 (same package but different pin function mapping) or older NTB0102 variants lacking Q100 qualification. PCB layout must follow the specific pin configuration shown in Figure 2 of the datasheet.
Does NTB0102DP-Q100H require external pull-up resistors on its I/O lines?
No-external pull-up or pull-down resistors are not required and are discouraged. The NTB0102DP-Q100H has weak static drive strength by design to avoid contention; using resistors below 50 kΩ risks output contention and violates the device's operational specification. It is not intended for open-drain buses like I²C-use NTS0102DP-Q100 instead for those applications.
How does the IOFF feature protect the NTB0102DP-Q100H during power sequencing?
The IOFF circuitry in NTB0102DP-Q100H disables all outputs when either VCC(A) or VCC(B) falls to GND, preventing backflow current through the device. This eliminates risk of damage during asymmetric power-up/down sequences-common in automotive domain-isolated architectures-and ensures safe hot-plug operation in modular ECU designs where supplies may ramp independently.
