Product details
Overview
74CBTLV3126PW-Q10J from Nexperia is an automotive-qualified 4-bit CMOS bus switch with independent output enable inputs (1OE–4OE), 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 path isolation for ADAS domain controllers and infotainment serial buses.
For engineers reviewing the 74CBTLV3126PW-Q10J datasheet, 74CBTLV3126PW-Q10J pinout, 74CBTLV3126PW-Q10J application, or 74CBTLV3126PW-Q10J equivalent, key selection criteria include guaranteed sub-0.31 ns propagation delay at 3.6 V, Schmitt-triggered OE inputs tolerant of slow edges, IOFF leakage < ±50 μA during power sequencing, and TSSOP14 package compatibility with AOI-capable SMT lines.
Technical Context
This device implements four independent bilateral analog switches controlled by dedicated OE pins, enabling selective channel gating without affecting adjacent data paths. Each switch exhibits rail-to-rail conduction, supports bidirectional signal flow, and maintains high noise immunity via Schmitt-trigger inputs across the full 2.3–3.6 V supply range.
The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±50 μA and enabling hot-swap and partial power-down operation. Switch resistance varies with input voltage and temperature: 4.0–7.0 Ω (typ) at 3.3 V/25 °C with 64 mA load, rising to ≤11.0 Ω at +125 °C.
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 logic domains without level translation. |
| ON Resistance | 4.0–7.0 Ω (typ) at VCC = 3.3 V - Ensures minimal insertion loss and < 0.22 V drop at 64 mA, preserving signal integrity. |
| Propagation Delay | ≤ 0.31 ns (max) at VCC = 3.6 V - Supports >1 GHz data rates in high-speed parallel bus isolation applications. |
| IOFF Leakage | ±50 μA max at VCC = 0 V - Prevents damaging back-current during power sequencing in multi-rail automotive ECUs. |
| Operating Temperature | –40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and body-control module deployment. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets automotive robustness requirements for assembly and field operation. |
| Switch Capacitance | 14.3 pF (ON), 5.2 pF (OFF) at 3.3 V - Minimizes capacitive loading on source and destination nodes during active/passive states. |
Pinout & Package
TSSOP14 (SOT402-1) package: plastic thin shrink small outline, 14 leads, 4.4 mm body width, side-wettable flanks for automated optical inspection (AOI) of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1OE, 2OE, 3OE, 4OE | Independent output enable inputs - Drive LOW to disable corresponding A↔B switch; Schmitt-triggered for noise immunity. |
| 2, 5, 9, 12 | 1A, 2A, 3A, 4A | Bidirectional data port A - Connects to upstream logic or controller; supports rail-to-rail analog/digital signals. |
| 3, 6, 8, 11 | 1B, 2B, 3B, 4B | Bidirectional data port B - Connects to downstream bus or peripheral; electrically identical to A port. |
| 7 | GND | Ground reference (0 V) - Required for biasing all internal circuitry and ESD protection networks. |
| 14 | VCC | Power supply input - Must be decoupled locally; IOFF functionality requires this pin to be at 0 V for power-down mode. |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-channel OE control | Enables granular bus segmentation - e.g., isolate CAN transceiver TX while keeping RX active in fault-tolerant gateways. |
| IOFF partial power-down | Blocks back-current when VCC = 0 V, allowing safe insertion/removal in live backplanes or modular ECU architectures. |
| Rail-to-rail analog switching | Supports full-swing signals from GND to VCC without clipping - critical for accurate sensor data routing in ADC front-ends. |
| Low 5 Ω ON-resistance | Reduces voltage drop and timing skew across parallel data lines, maintaining setup/hold margins in 100+ MHz memory interfaces. |
| Side-wettable flanks (TSSOP) | Enables automated optical inspection of solder joint quality - essential for zero-defect manufacturing in automotive Tier-1 production. |
Applications
| ADAS Sensor Data Multiplexing | Infotainment Serial Bus Isolation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-bit bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74CBTLV3126BQ-Q100 | DHVQFN14 package (2.5 × 3 mm), no leads, thermal-enhanced; same electrical specs. | Better thermal performance in space-constrained modules; requires different stencil design and reflow profile. | Select for high-power-density designs where board area and junction temperature are critical. |
| SN74CBTLV3126PWR | Industrial-grade (not AEC-Q100 qualified); identical pinout and function; wider VCC range (2.3–3.6 V). | Not suitable for automotive safety-critical systems; lacks AEC-Q100 Grade 1 temperature validation. | Use only in non-automotive industrial or consumer applications requiring cost optimization. |

FAQ
What is the maximum allowable voltage on A/B pins when VCC = 0 V?
The absolute maximum switch voltage rating is VCC + 0.5 V. When VCC = 0 V, the A/B pins must remain within –0.5 V to +0.5 V to avoid violating limiting values. Exceeding this risks permanent damage due to forward-biasing internal ESD diodes, even with IOFF enabled.
Can multiple 74CBTLV3126PW-Q10J devices be cascaded for wider bus widths?
Yes - the device supports cascading via A-to-B or B-to-A connections. Propagation delay adds linearly (e.g., two devices yield ≤0.62 ns max at 3.6 V), and ON-resistance accumulates (e.g., 14 Ω total at 3.3 V). Maintain load capacitance ≤30 pF per stage to preserve signal fidelity.
Is a pull-down resistor required on each OE pin?
Yes - to guarantee high-impedance OFF-state during power-up/down, each OE pin must be pulled to GND. The minimum resistor value depends on the driver's sink capability; Nexperia specifies ≥10 kΩ for standard CMOS drivers, but ≤4.7 kΩ is recommended for robust noise immunity in automotive harness environments.
Does the TSSOP14 package support lead-free reflow profiles?
Yes - the SOT402-1 package is qualified for JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and withstands peak reflow temperatures up to 260 °C. Its side-wettable flanks are compatible with standard lead-free SAC305 profiles, including ramp-to-spike and soak profiles defined in IPC-J-STD-020.
