Product details
Overview
NXS0102DC-Q100 from Nexperia is an automotive-grade, 2-bit dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and open-drain I/O architecture. It supports simultaneous 1.65–3.6 V (VCC(A)) and 2.3–5.5 V (VCC(B)) operation, enabling translation between 1.8 V, 2.5 V, 3.3 V, and 5.0 V domains. Its IOFF circuitry ensures partial power-down protection, and it operates across –40 °C to +125 °C for under-hood automotive interfaces.
For engineers reviewing the NXS0102DC-Q100 datasheet, NXS0102DC-Q100 pinout, NXS0102DC-Q100 application in I²C or 1-wire bus bridging, or NXS0102DC-Q100 equivalent for AEC-Q100 Grade 1 level-shifting, this device delivers verified 24 Mbps push-pull data rate, <7.5 ns propagation delay (A→B at 3.3 V), and integrated 10 kΩ internal pull-ups per port - critical for robust low-power automotive serial communication.
Technical Context
The NXS0102DC-Q100 implements a switch-type voltage translator using pass-gate NMOS (T3) biased ~1 VTH above VCC(A), enabling seamless bidirectional conduction without external direction control. Its dual one-shot edge accelerators detect input transitions at ~0.5×VCCI and temporarily activate PMOS transistors (T1/T2) to reduce rising-edge transition time.
Internal 10 kΩ pull-up resistors on both A and B ports eliminate external biasing for open-drain protocols like I²C. The IOFF circuit disables outputs and blocks backflow current when either supply is powered down, satisfying partial power-down requirements per JESD78B Class II latch-up (>100 mA) and AEC-Q100 stress testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - powers A-side logic and defines OE input threshold; must be ≤ VCC(B) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply bidirectional level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102QPWRQ1 | TI device uses different auto-direction algorithm; higher ICC(A) (15 μA vs. 0.1 μA typical); no internal pull-ups | Requires external 10 kΩ pull-ups on both sides; less suitable for space-constrained modules where BOM reduction is critical | Select NXS0102DC-Q100 when minimizing external components and achieving ultra-low static current in always-on domains is required. |
| NXB0102DC-Q100 | Nexperia's push-pull optimized variant; lacks auto-direction sensing; requires explicit DIR control signal | Better for unidirectional high-speed links (e.g., SPI); not usable in I²C without added GPIO and firmware logic | Choose NXS0102DC-Q100 for I²C/1-wire where direction ambiguity exists and zero-GPIO translation is mandatory. |
Compared with TXS0102QPWRQ1 and NXB0102DC-Q100, the NXS0102DC-Q100 uniquely combines auto-direction sensing, integrated pull-ups, and sub-1 μA IOFF leakage - making it the only AEC-Q100 Grade 1 solution that eliminates both direction control logic and external biasing in automotive serial bridges.

FAQ
Is NXS0102DC-Q100 compatible with I²C Fast-mode Plus (1 Mbps)?
Yes. With a verified 24 Mbps push-pull data rate and propagation delays ≤7.5 ns at 3.3 V/5.0 V, the NXS0102DC-Q100 fully supports I²C Fast-mode Plus timing budgets. Its auto-direction sensing and open-drain compatibility eliminate bus contention risks, and internal 10 kΩ pull-ups meet standard I²C pull-up requirements without external components.
What happens if VCC(A) exceeds VCC(B) during normal operation?
VCC(A) must never exceed VCC(B) during active operation per datasheet Section 10 - doing so violates absolute maximum ratings and may cause latch-up or permanent damage. However, during power-up sequencing, transient VCC(A) ≥ VCC(B) is permitted and non-damaging due to built-in protection circuitry.
Does the device require external pull-up resistors for I²C operation?
No. Each A-port pin (A1, A2) integrates a 10 kΩ pull-up to VCC(A), and each B-port pin (B1, B2) integrates a 10 kΩ pull-up to VCC(B). These are sufficient for standard-mode and Fast-mode I²C; only Fast-mode Plus or heavy capacitive loads may require supplemental external pull-ups.
How does the IOFF circuit protect during partial power-down?
When either VCC(A) or VCC(B) drops to 0 V, the IOFF circuit actively disables all I/O paths and limits leakage current to ±1 μA maximum. This prevents backflow current from the powered domain into the unpowered domain - a critical requirement for domain-isolated automotive ECUs and validated per JESD78B Class II latch-up testing.
