Product details

Overview

NTS0104BQ,115 from NXP Semiconductors is a 4-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in DHVQFN14 package. It enables seamless translation between 1.8 V/2.5 V/3.3 V and 5.0 V domains (VCC(A): 1.65–3.6 V; VCC(B): 2.3–5.5 V), supports 50 Mbps push-pull data rates, features IOFF partial power-down protection, and operates across −40 °C to +125 °C for I²C/SMBus and GPIO interfacing.

For engineers reviewing the NTS0104BQ,115 datasheet, NTS0104BQ,115 pinout, NTS0104BQ,115 application, or NTS0104BQ,115 equivalent, key selection criteria include its open-drain-compatible auto-direction sensing architecture, dual-rail supply independence, IOFF-enabled safe power sequencing, ESD robustness (8 kV HBM on B port), and thermal-enhanced DHVQFN14 footprint for high-density mixed-voltage board designs.

Technical Context

The NTS0104BQ,115 implements a switch-type voltage translation architecture using pass-gate N-channel transistors with dynamically biased gate control-set ~1 V_TH above the lower supply rail-to maintain low-conduction loss across voltage domains. Its auto-direction sensing eliminates external direction-control signals by detecting edge polarity on either port.

Each I/O channel integrates an output edge-rate accelerator (one-shot circuit) that activates at ~V_CCI/2 to temporarily bypass internal 10 kΩ pull-ups with low-impedance PMOS drivers (50–70 Ω), reducing t_TLH and enabling 50 Mbps operation. The device includes integrated 10 kΩ pull-up resistors per port referenced to their respective supplies and disables all outputs when either VCC(A) or VCC(B) is at GND.

Key Specifications

Parameter	Value and Actual Design Meaning

A1–A4	Bi-directional data port (A side)	Referenced to VCC(A); each has internal 10 kΩ pull-up to VCC(A); auto-senses direction on signal edges.
B1–B4	Bi-directional data port (B side)	Referenced to VCC(B); each has internal 10 kΩ pull-up to VCC(B); tolerant of inputs up to 5.5 V.
OE	Active-HIGH output enable	Referenced to VCC(A); LOW forces all ports into high-impedance OFF-state; t_dis = 45 ns max at +125 °C.
GND	Common ground reference	Single ground plane required; substrate connection point; must be low-impedance for noise immunity and ESD path.

Key Features

Feature	Design Value
Auto-direction sensing	Eliminates need for external DIR control line-reduces PCB routing, firmware overhead, and component count in bidirectional buses like I²C.
Integrated 10 kΩ pull-ups	Removes requirement for four external pull-up resistors per port, simplifying BOM and layout while ensuring defined idle states.
IOFF partial power-down	Prevents current backflow when either supply is off-enables safe hot-plug operation and extends battery life in portable systems.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TXS0104E	4-bit auto-direction translator in VQFN14; VCC(A): 1.2–3.6 V, VCC(B): 1.65–5.5 V; 60 Mbps max; no integrated pull-ups.	Requires external 10 kΩ pull-ups on both sides; better suited for ultra-low-voltage (1.2 V) A-side interfaces.	Select TXS0104E only if A-side supply drops below 1.65 V or higher speed (>50 Mbps) is required with external pull-up optimization.
PCA9306	2-bit dual-supply translator in UQFN8; VCC(A): 1.2–3.6 V, VCC(B): 1.8–5.5 V; 2 Mbps max; integrated 10 kΩ pull-ups; no OE pin.	Lacks output enable and thermal enhancement; limited to low-speed I²C; 2-channel only.	Choose PCA9306 for cost-sensitive, space-constrained 2-wire I²C bridges where OE control and 50 Mbps are unnecessary.

Compared with TXS0104E and PCA9306, the NTS0104BQ,115 uniquely combines integrated pull-ups, OE control, 50 Mbps performance, and −40 °C to +125 °C qualification in a thermally optimized 14-terminal QFN-making it optimal for robust, high-density, mixed-voltage industrial and automotive control interfaces.

FAQ

What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0104BQ,115?

The NTS0104BQ,115 requires VCC(A) ≤ VCC(B) during normal operation to ensure correct pass-gate biasing and avoid overstress. While VCC(A) may transiently exceed VCC(B) during power-up without damage, sustained operation with VCC(A) > VCC(B) violates the recommended operating condition and risks unreliable translation or increased leakage. The absolute maximum ratings allow both supplies up to +6.5 V independently, but functional specification mandates VCC(A) ≤ VCC(B).

Does the NTS0104BQ,115 support true push-pull drivers on both A and B ports, or is it limited to open-drain configurations?

The NTS0104BQ,115 supports both open-drain and push-pull drivers on either port. Its switch-based architecture functions correctly with actively driven HIGH/LOW signals, though the datasheet notes that push-pull use cases may benefit from the NTB0104 variant. For push-pull operation, the NTS0104BQ,115 delivers 50 Mbps data rates with propagation delays under 7.3 ns and maintains full IOFF protection during power-down.

How does the internal 10 kΩ pull-up resistor on each port affect VOL and drive strength in the NTS0104BQ,115?

The NTS0104BQ,115's internal 10 kΩ pull-up resistors define the weak HIGH-state current sourcing capability-resulting in typical VOL < 0.4 V at 1 mA sink load. When stronger drive is needed (e.g., faster rise times or heavier capacitive loads), external parallel pull-ups can be added, but this lowers effective resistance and increases static current. During OE = LOW, internal pull-ups are disabled, placing ports in true high-impedance state.

Can the NTS0104BQ,115 be used in I²C applications requiring clock stretching, and how does auto-direction sensing handle bidirectional SCL arbitration?

Yes, the NTS0104BQ,115 fully supports I²C clock stretching and multi-master arbitration. Its auto-direction sensing responds to voltage transitions on either side in real time-ensuring transparent bidirectional flow during SCL hold conditions. The device's <0.8 ns output skew and sub-7 ns propagation delay preserve I²C timing budgets, while IOFF prevents contention during master handover or power cycling of individual nodes.

What thermal design considerations apply to the DHVQFN14 package of the NTS0104BQ,115 in high-ambient-temperature environments?

The DHVQFN14 (SOT762-1) package of the NTS0104BQ,115 features an exposed thermal pad optimized for PCB heat dissipation. For operation at +125 °C ambient, Aetrix recommends a minimum 4-layer board with ≥4 thermal vias (0.3 mm diameter) under the pad connected to an internal ground plane. Power dissipation derates linearly at 4.5 mW/K above +60 °C, limiting P_tot to ~210 mW at +125 °C-well within the 250 mW absolute maximum.
