Product details
Overview
74CBTLV3253BQ-Q10X from Nexperia is an automotive-qualified dual 1-of-4 CMOS bus switch with two independent 4-channel multiplexer/demultiplexer paths, 5 Ω typical ON-resistance at 3.3 V, rail-to-rail signal switching, and IOFF partial power-down protection. It operates from 2.3 V to 3.6 V across -40 °C to +125 °C and is used in high-speed data routing for ADAS sensor interfaces and infotainment baseband signal management.
For engineers reviewing the 74CBTLV3253BQ-Q10X datasheet, 74CBTLV3253BQ-Q10X pinout, 74CBTLV3253BQ-Q10X application, or 74CBTLV3253BQ-Q10X equivalent, key selection criteria include guaranteed low ON-resistance over temperature, AEC-Q100 Grade 1 qualification, Schmitt-trigger control inputs for noise immunity, and DHVQFN16 package compatibility with AOI-enabled automotive PCB assembly.
Technical Context
This device implements two independent bidirectional analog/digital bus switches, each selecting one of four B-port terminals (1B1–1B4 or 2B1–2B4) to connect to its respective A-port (1A or 2A) using shared S0/S1 select lines and separate 1OE/2OE enable controls. All switches exhibit rail-to-rail voltage handling and zero propagation delay in the ON-state.
The IOFF circuit ensures leakage current remains below ±50 μA when VCC = 0 V, enabling safe hot-insertion and partial power-down operation. Schmitt-trigger inputs on S0, S1, 1OE, and 2OE tolerate slow edge rates up to 200 ns/V across the full supply range, eliminating external conditioning in noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3 V to 3.6 V - Enables direct interface with 2.5 V and 3.3 V automotive microcontrollers and sensors without level-shifting. |
| ON Resistance (RON) | Typ. 4.0 Ω at VCC = 3.3 V, ISW = 64 mA - Ensures minimal signal attenuation and <0.25 ns propagation delay for high-fidelity data routing. |
| Operating Temperature | -40 °C to +125 °C - Fully specified for under-hood and infotainment module deployment per AEC-Q100 Grade 1. |
| IOFF Leakage | ±50 μA max at VCC = 0 V - Prevents backflow current during power sequencing, supporting robust system-level power management. |
| Switch Capacitance | CS(ON) = 20.0 pF, CS(OFF) = 5.2 pF - Minimizes crosstalk and maintains >300 MHz -3 dB bandwidth for video and high-speed serial signals. |
| Enable/Disable Time | ten/tdis ≤ 4.4 ns max at VCC = 3.6 V - Supports fast channel reconfiguration in time-critical sensor fusion applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Withstands assembly handling and in-system electrostatic events without latch-up or parametric shift. |
Pinout & Package
DHVQFN16 (SOT763-1) package: 2.5 × 3.5 × 0.85 mm body, side-wettable flanks for automated optical inspection of solder joints, thermally enhanced for automotive reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15 | 1OE, 2OE | Active-LOW output enable inputs - Drive LOW to activate corresponding 4-channel path; HIGH places all switches in high-Z OFF-state. |
| 2, 14 | S1, S0 | Binary select inputs - Encode 00–11 to route 1A↔1Bn or 2A↔2Bn; Schmitt-triggered for noise immunity. |
| 3–6, 10–13 | 1B1–1B4, 2B1–2B4 | B-side bidirectional I/O terminals - Support rail-to-rail analog/digital signals; no direction pin required. |
| 7, 9 | 1A, 2A | A-side bidirectional I/O terminals - Serve as common ports for each 4:1 mux/demux path. |
| 8 | GND | Ground reference - Must be connected to system ground plane; thermal pad (pin 1 index area) may be left floating or tied to GND. |
| 16 | VCC | Supply voltage input - Requires local 100 nF ceramic decoupling; IOFF protection active when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 1-of-4 switching | Enables simultaneous routing of two separate data streams (e.g., camera + radar baseband) without cross-talk or timing skew. |
| 5 Ω typical ON-resistance | Preserves signal integrity for high-speed parallel buses and LVDS-adjacent interfaces with <1% voltage drop at 100 mA. |
| IOFF partial power-down | Allows one section to remain powered while another is off, critical for domain controller power gating strategies. |
| Schmitt-trigger control inputs | Accepts slow-rising signals (≥200 ns/V) from mechanical switches or legacy MCUs without external hysteresis components. |
| DHVQFN16 with side-wettable flanks | Supports automated optical inspection of solder joints - essential for zero-defect automotive manufacturing compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 1-of-4 bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G3157GV-Q100 | Single-channel, 5-pin SC-70 package; RON = 6 Ω typical at 3.3 V; no shared select lines. | Limited to one 2:1 path; lacks dual independent control and 4:1 flexibility. | Select only when space-constrained single-path routing suffices and S0/S1 sharing is unnecessary. |
| SN74CBT3253QPWRQ1 | TSSOP16 package; RON = 7 Ω typical at 3.3 V; no AEC-Q100 Grade 1 rating; IOFF not characterized for automotive temp range. | Not qualified for under-hood use; requires external ESD protection beyond HBM 2000 V. | Acceptable only for cabin-grade infotainment modules where extended temperature and qualification are not mandated. |
Compared with 74CBTLV3253BQ-Q10X, the LVC1G3157 offers smaller footprint but sacrifices dual-path capability and select-line efficiency, while the SN74CBT3253QPWRQ1 trades automotive qualification and lower RON for legacy TI ecosystem compatibility.

FAQ
What is the maximum allowable voltage on the B-port terminals when VCC = 0 V?
The absolute maximum switch voltage rating is VCC + 0.5 V, so with VCC = 0 V, the B-port can tolerate -0.5 V to +0.5 V. Exceeding this range risks damage per Table 4 limiting values. The IOFF circuit holds leakage to ±50 μA within this window, but sustained bias outside ±0.5 V violates absolute maximum ratings and may cause permanent degradation.
Can S0 and S1 be driven directly from a 1.8 V GPIO without level translation?
No. Input voltage thresholds VIH and VIL are referenced to VCC: VIH ≥ 2.0 V (min) at VCC = 3.0–3.6 V, and VIH ≥ 1.7 V at VCC = 2.3–2.7 V. A 1.8 V signal falls below both thresholds and will not reliably register as HIGH. Level translation or a VCC-compatible controller is required.
Is the thermal pad (pin 1 index area) electrically connected to GND internally?
No. Per Figure 4 note (1), the exposed thermal pad has no electrical or mechanical requirement to be soldered. If soldered, it must remain electrically floating or be connected to GND - it is not internally bonded to the die substrate or any internal node.
How does the device behave when 1OE is HIGH and 2OE is LOW?
When 1OE = HIGH, all switches in Path 1 (1A ↔ 1B1–1B4) are forced into high-impedance OFF-state regardless of S0/S1 states. When 2OE = LOW, Path 2 (2A ↔ 2B1–2B4) operates normally: S0/S1 determine which 2Bn connects to 2A. The two paths operate independently - no interaction or contention occurs.
