Product details
Overview
74CBTLV3125PW-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 within automotive infotainment and ADAS domain controllers.
For engineers reviewing the 74CBTLV3125PW-Q10J datasheet, 74CBTLV3125PW-Q10J pinout, 74CBTLV3125PW-Q10J application, or 74CBTLV3125PW-Q10J equivalent, key selection criteria include guaranteed sub-0.31 ns propagation delay, Schmitt-trigger control inputs for noise immunity, IOFF-enabled hot-swap capability, and TSSOP14 package compatibility with AOI-verified solder joints.
Technical Context
This device implements four independent bilateral analog switches, each controlled by a dedicated OE input. Each switch exhibits rail-to-rail conduction with no level-shifting-signals from 0 V to VCC pass unattenuated when enabled.
The IOFF circuit actively disables all switches and limits leakage to ±50 μA when VCC = 0 V, enabling safe back-drive prevention during partial power-down. Schmitt-trigger inputs on all OE pins ensure robust operation with slow-rising/falling control signals across the full 2.3–3.6 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.3 V to 3.6 V - supports dual-voltage system interfacing (e.g., 2.5 V logic driving 3.3 V subsystems) |
| ON resistance | Typ. 4.0 Ω at VCC = 3.3 V, ISW = 64 mA - enables <10 mV drop at 100 mA, preserving signal integrity |
| Propagation delay | Typ. 0.20 ns at VCC = 3.3 V - suitable for >1 GHz data paths without timing budget impact |
| IOFF leakage | ±50 μA max at VCC = 0 V - prevents damaging back-current during hot-insertion or power sequencing |
| Operating temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| ESD rating | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events in production environments |
| Enable/disable time | Typ. 2.4 ns enable / 2.9 ns disable at VCC = 3.3 V - ensures precise timing control in synchronous bus gating |
Pinout & Package
TSSOP14 (SOT402-1) package: plastic thin shrink small outline, 14-lead, 4.4 mm body width, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1OE, 2OE, 3OE, 4OE | Independent active-low enable inputs - each controls one switch pair; HIGH forces high-impedance OFF-state |
| 2, 5, 9, 12 | 1A, 2A, 3A, 4A | Bidirectional data port A - connects to upstream logic or controller; rail-to-rail compatible |
| 3, 6, 8, 11 | 1B, 2B, 3B, 4B | Bidirectional data port B - connects to downstream load or bus segment; identical electrical behavior to A |
| 7 | GND | Ground reference - must be connected to system 0 V; decoupling capacitor recommended near pin |
| 14 | VCC | Positive supply - requires local 100 nF ceramic decoupling; tie OE pins to VCC via pull-up for power-up safety |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-channel enable | Four separate OE inputs allow selective activation of individual data paths without affecting others |
| Rail-to-rail analog switching | Supports DC-coupled signals from 0 V to VCC - eliminates level-shifter requirement in mixed-voltage buses |
| IOFF partial power-down | Switches automatically enter high-Z state with <±50 μA leakage when VCC = 0 V - enables live insertion/removal |
| Schmitt-trigger OE inputs | Hysteresis ≥0.3 V across full VCC range - rejects noise on control lines without external filtering |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40 °C to +125 °C ambient - meets reliability and lifetime requirements for Tier-1 systems |
Applications
| Automotive Infotainment Bus Isolation | ADAS Sensor Data Multiplexing |
|---|---|
Use Scenario: Isolating LVDS or parallel video data paths between head unit SoC and display module during sleep/wake transitions. IC Role / Device Role / Timing Role: Bidirectional analog switch enabling/disabling high-speed pixel data lanes while maintaining signal fidelity. Use Value: Prevents signal contention and ground bounce during power-state changes; sub-0.3 ns delay avoids skew-induced image artifacts. |
Use Scenario: Time-shared routing of camera sensor outputs (e.g., rear-view + surround-view) to a single image processor input. IC Role / Device Role / Timing Role: Low-latency multiplexer selecting between multiple MIPI CSI-2 source streams without clock domain crossing. Use Value: 5 Ω RON preserves rise/fall times for 100+ MHz pixel clocks; IOFF blocks backfeed when inactive sensors are powered down. |
| Body Control Module Signal Gating | Automotive Gateway CAN/LIN Interface Buffering |
Use Scenario: Enabling/disabling diagnostic communication lines (e.g., UDS over UART) between gateway MCU and submodules only during active sessions. IC Role / Device Role / Timing Role: Controlled signal gate preventing leakage current and electromagnetic interference on idle lines. Use Value: Schmitt-trigger OE inputs tolerate noisy chassis-ground-referenced control signals; ±1 μA leakage maintains low-power sleep current budgets. |
Use Scenario: Isolating LIN transceiver I/O from main microcontroller during firmware updates to prevent bus corruption. IC Role / Device Role / Timing Role: High-impedance barrier inserted between MCU GPIO and LIN PHY during reprogramming sequences. Use Value: IOFF ensures zero current flow into powered-down MCU pins; 3.6 V max VCC supports direct connection to 3.3 V LIN PHY supplies. |
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 |
|---|---|---|---|
| 74CBTLV3125BQ-Q100 | DHVQFN14 package (2.5 × 3 mm), no leads, thermal-enhanced; same electrical specs | Better thermal performance and smaller footprint - preferred for space-constrained ADAS ECUs | Select when PCB real estate or junction temperature margin is critical; requires reflow profile adjustment for QFN |
| SN74CBT3125QPWRQ1 | Texas Instruments part; 5.5 V max VCC, higher RON (7 Ω typ), non-AEC-Q100 but PPAP-capable | Broader supply range allows legacy 5 V subsystem integration; lacks IOFF and Schmitt triggers | Choose only if interfacing with 5 V logic; requires external pull-ups and power sequencing design to replace IOFF functionality |
Compared with 74CBTLV3125BQ-Q100, the PW-Q10J offers easier optical inspection and standard TSSOP rework; versus SN74CBT3125QPWRQ1, it delivers lower RON, guaranteed IOFF, and superior noise immunity-critical for modern automotive signal integrity.

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 may tolerate –0.5 V to +0.5 V. Exceeding this risks latch-up or permanent damage, as confirmed in Table 4 (Limiting Values). IOFF protection does not extend beyond these absolute ratings.
Can 1OE–4OE be tied together and driven by a single controller output?
Yes-OE inputs are electrically independent but share identical logic thresholds and drive strength. Connecting them simplifies control at the cost of losing per-channel gating. Ensure the combined capacitive load remains within the driver's fan-out capability; total input capacitance is 4 × 0.9 pF = 3.6 pF.
Is external pull-up required on OE pins during power-up?
Yes. To guarantee high-impedance OFF-state at power-on, each OE must be pulled HIGH via resistor to VCC. The minimum value depends on the driver's sink current; Nexperia recommends ≥10 kΩ for typical microcontroller GPIOs, per Section 1 General Description.
Does the device support hot-swap in live-backplane applications?
Yes-IOFF circuitry ensures all switches enter high-Z state with ≤±50 μA leakage when VCC = 0 V, preventing back-current flow into unpowered sections. This enables safe insertion into powered backplanes, provided A/B pin voltages stay within –0.5 V to VCC + 0.5 V limits.
