Product details

Overview

NXB0106 from Nexperia is a 6-bit dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and 3-state output control. It enables seamless interfacing between 1.2 V–3.6 V (A-side) and 1.65 V–5.5 V (B-side) domains, supports up to 110 Mbps data rate at 3.3 V/5.0 V, and features IOFF circuitry for partial power-down protection. It is used in mixed-voltage system interconnects such as FPGA-to-ASIC or microcontroller-to-peripheral communication.

For engineers reviewing the NXB0106 datasheet, NXB0106 pinout, NXB0106 application, or NXB0106 equivalent, key selection considerations include its auto-direction architecture (no external DIR signal required), asymmetric supply tolerance (VCC(A) ≤ VCC(B)), IOFF-enabled safe power sequencing, and compatibility with 1.2 V, 1.8 V, 3.3 V, and 5.0 V logic families across industrial temperature range (−40 °C to +125 °C).

Technical Context

The NXB0106 implements edge-triggered one-shot circuitry on both A and B ports to dynamically detect data flow direction and enable corresponding output drivers without external control. Its I/O cells use weak static drive (70 Ω typical at 1.2–1.8 V, 50 Ω at 1.8–3.3 V) to allow bus contention resolution during direction transitions.

IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) drops to GND, preventing backflow current and enabling hot-swap capability. Input thresholds are referenced to respective supply rails (VIH = 0.65×VCCI, VIL = 0.35×VCCI), and OE is referenced solely to VCC(A), requiring no level shifting for enable control.

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; must be ≤ VCC(B) during operation
VCC(B) Range	1.65 V to 5.5 V - powers B-side I/Os; supports legacy 5 V and modern low-voltage systems
Data Rate	Up to 110 Mbps - verified at VCC(A)=3.3 V, VCC(B)=5.0 V, −40 °C to +125 °C
Propagation Delay	0.8 ns (min) to 11.9 ns (max) - varies by supply pair and temperature; B→A slightly slower than A→B
IOFF Leakage	±2 μA max (−40 °C to +125 °C) - ensures <1 μA backflow during partial power-down
ESD Robustness	HBM 15 kV on B port, 2.5 kV on A port - protects against handling and board-level ESD events
Operating Temp	−40 °C to +125 °C - qualified for automotive under-hood and industrial control applications

Pinout & Package

TSSOP16 (SOT403-1) package: plastic thin shrink small outline, 16-pin, 4.4 mm body width, 0.65 mm pitch, lead-free and RoHS compliant.

Pin/Terminal	Circuit Role	Design Meaning
A1–A6	A-side bidirectional data I/O	Referenced to VCC(A); accept inputs up to 5.5 V; drive outputs to VCC(A)
B1–B6	B-side bidirectional data I/O	Referenced to VCC(B); tolerate 0–5.5 V; drive outputs to VCC(B)
OE	Output enable (active HIGH)	Referenced to VCC(A); LOW forces all I/Os into high-impedance state
VCC(A)	A-side supply rail	Powers A-port logic, OE input, and internal one-shots; must be ≤ VCC(B)
VCC(B)	B-side supply rail	Powers B-port logic and output drivers; sets B-side VOH/VOL levels
GND	Common reference ground	Single ground connection shared by both sides; required for voltage referencing

Key Features

Feature	Design Value
Auto-direction sensing	Eliminates need for external DIR signal; detects data flow via edge-triggered one-shots on both ports
Dual independent supply rails	VCC(A): 1.2–3.6 V; VCC(B): 1.65–5.5 V - enables translation across 1.2 V ↔ 5.0 V without intermediate regulators
IOFF partial power-down	Disables outputs and limits leakage to ±2 μA when either supply is off - prevents backfeed in hot-plug scenarios
High-speed performance	110 Mbps max data rate with <12 ns propagation delay - suitable for DDR, SPI, and parallel bus interfaces
Robust ESD protection	15 kV HBM on B port, 2.5 kV on A port - exceeds JEDEC JS-001 Class 3B for system-level reliability

Applications

IC Role / Device Role / Timing Role: Dual-rail transceiver enabling direct connection of FPGA I/O to 5 V UART, GPIO, or ADC peripherals.

Use Value: Supports full 110 Mbps throughput at 3.3 V/5.0 V, avoids level-shifter IC proliferation, and guarantees safe power sequencing via IOFF during FPGA configuration reset.

Automotive Body Control Module

Use Scenario: Interfacing 1.8 V microcontroller to 3.3 V CAN transceiver and 5.0 V LIN driver in an under-hood BCM.

IC Role / Device Role / Timing Role: Voltage translator with −40 °C to +125 °C operation; manages bidirectional status/control signals across supply domains.

Use Value: IOFF prevents battery drain during sleep mode; 15 kV B-port ESD withstand protects against load-dump-induced transients on 5 V lines.

Use Scenario: Bridging 1.5 V BMC processor I²C bus to 3.3 V thermal sensor array and 5.0 V fan controller on a server motherboard.

Equivalent & Alternatives

The following parts are listed as comparable options for similar bidirectional voltage translation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TXS0108E	8-bit, 5 V tolerant B-side, but requires external pull-up resistors on B port; no IOFF; max 60 Mbps	Designed for open-drain I²C; unsuitable for push-pull buses due to weak drive strength	Select only if I²C/SMBus is primary interface and 5 V pull-ups are acceptable
NXS0106	Same 6-bit auto-direction architecture, but optimized for open-drain (I²C/1-Wire); includes stronger pull-up drivers	Supports true bidirectional open-drain signaling; lacks high-speed push-pull capability	Prefer for I²C applications; avoid for SPI/parallel where NXB0106's 110 Mbps and push-pull drive are required

Compared with TXS0108E and NXS0106, the NXB0106 uniquely combines high-speed push-pull translation (110 Mbps), IOFF safety, and wide dual-supply flexibility - making it optimal for mixed-voltage parallel or burst-mode serial interfaces where direction control overhead and power sequencing integrity are critical.

FAQ

Can NXB0106 translate between 1.2 V and 5.0 V simultaneously?

Yes. With VCC(A) = 1.2 V and VCC(B) = 5.0 V, the device fully supports bidirectional translation: A-side inputs accept up to 5.5 V (safe for 5 V signals), and B-side outputs swing to 5.0 V. Static characteristics (VOH/VOL, VIH/VIL) are guaranteed across this combination per Table 8, and dynamic performance reaches 40 Mbps at −40 °C to +125 °C.

Is external direction control required for NXB0106?

No. The device uses internal edge-detecting one-shot circuits on both A and B ports to autonomously enable the correct output driver based on signal transition direction. This eliminates the need for a dedicated DIR pin, simplifying PCB layout and reducing FPGA/GPIO resource usage in multi-channel designs.

What happens if VCC(A) exceeds VCC(B) during normal operation?

VCC(A) must not exceed VCC(B) during active operation per datasheet requirement (Section 8, Note [2]). Exceeding this violates absolute maximum ratings and may cause latch-up or accelerated wear. However, during power-up/power-down, transient VCC(A) ≥ VCC(B) is permitted and non-damaging due to built-in power-fail detection and IOFF activation.

Does NXB0106 support I²C or 1-Wire protocols?

No. Its push-pull output architecture and minimum 50 kΩ pull-up/pull-down requirement (Section 11.6) make it incompatible with open-drain buses like I²C or 1-Wire. For those protocols, Nexperia recommends NXS0106 - a functionally similar part with integrated strong pull-up drivers and optimized rise-time control.
