Product details
Overview
CBT3306PW-Q100 from Nexperia is an automotive-qualified dual FET bus switch with independent 1A↔1B and 2A↔2B bidirectional signal paths, 5 Ω typical ON resistance at 4.5 V, TTL-compatible inputs, and operation from -40 °C to +85 °C - used for isolated data routing in automotive infotainment and body control modules.
For engineers reviewing the CBT3306PW-Q100 datasheet, CBT3306PW-Q100 pinout, CBT3306PW-Q100 application, or CBT3306PW-Q100 equivalent, key selection criteria include AEC-Q100 Grade 3 qualification, SO8 (SOT96-1) package compatibility, sub-5 ns enable/disable timing, and 5 Ω RON performance under 4.5–5.5 V supply conditions.
Technical Context
This device implements two independent analog bus switches using NMOS FETs with integrated level-shifting circuitry to ensure TTL-compatible input thresholds across the full automotive temperature range. Each channel features separate output-enable (1OE, 2OE) control pins that drive the associated switch into high-impedance OFF-state when HIGH.
Static characteristics are specified at VCC = 4.5–5.5 V, with pass voltage ≥3.6 V at 100 μA load and off-state capacitance ≤6.45 pF per port. Dynamic behavior includes 1.0–5.0 ns enable/disable times and 0.25 ns propagation delay between A/B ports under 50 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable switching in 5 V automotive domains without external regulation |
| ON Resistance | 5 Ω max at VCC = 4.5 V, II = 64 mA - enables low-loss bidirectional signal coupling below 100 mV drop at 20 mA |
| Enable/Disable Time | 1.0–5.0 ns - supports high-speed bus arbitration and hot-swap isolation in CAN/LIN subsystems |
| Input Compatibility | TTL-level (VIL ≤ 0.8 V, VIH ≥ 2.0 V) - interfaces directly with legacy microcontrollers and logic without level shifters |
| ESD Protection | HBM > 2000 V - meets automotive robustness requirements for assembly and field operation |
| Operating Temperature | -40 °C to +85 °C - qualified for passenger compartment and under-hood ECUs per AEC-Q100 Grade 3 |
Pinout & Package
CBT3306PW-Q100 is housed in an SO8 plastic small outline package (SOT96-1), 8-pin, 3.9 mm body width, with gull-wing leads and standard JEDEC MS-012 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable for first switch (1A ↔ 1B); HIGH disables path, LOW enables conduction |
| 2 | 1A | Port A terminal of first switch - bidirectional I/O node connected to MCU GPIO or peripheral bus |
| 3 | 1B | Port B terminal of first switch - bidirectional I/O node routed to sensor interface or display driver |
| 4 | GND | Ground reference for all internal circuitry and signal return path |
| 5 | 2A | Port A terminal of second switch - independent bidirectional path for auxiliary bus segment |
| 6 | 2B | Port B terminal of second switch - isolated signal path for diagnostics or backup communication line |
| 7 | 2OE | Active-low enable for second switch (2A ↔ 2B); independent control from 1OE |
| 8 | VCC | Positive supply input - powers internal level shifters and FET gates; decoupling required at pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 3 qualification | Validated for automotive use with full temperature range (-40 °C to +85 °C) and reliability testing per JESD47 |
| Independent dual-channel control | Separate 1OE and 2OE pins allow asynchronous enabling/disabling of each bus path for flexible power domain management |
| Low 5 Ω ON resistance | Minimizes voltage drop and signal distortion in 5 V digital buses carrying up to 20 mA per channel |
| Latch-up immunity >100 mA | Guarantees robustness against transient current surges during hot-plug or ESD events per JESD78B |
| Sub-5 ns switching latency | Enables real-time bus arbitration in time-critical applications such as LIN gateway arbitration or diagnostic multiplexing |
Applications
| Automotive Infotainment Bus Isolation | Body Control Module Signal Routing |
|---|---|
|
Use Scenario: Isolating USB or I²C signals between head unit MCU and touch controller during firmware update to prevent bus contention. IC Role / Device Role / Timing Role: Bidirectional analog switch providing galvanic separation while preserving signal integrity and timing alignment. Use Value: Enables safe concurrent updates without disabling entire infotainment subsystem; 5 Ω RON maintains <100 mV drop at 20 mA load. |
Use Scenario: Routing LIN bus signals between central gateway and door module controllers with selective channel enablement. IC Role / Device Role / Timing Role: Dual-channel bus switch acting as programmable signal bridge with independent OE control per LIN subnetwork. Use Value: Supports dynamic topology reconfiguration during sleep/wake transitions; 1.0–5.0 ns enable time aligns with LIN frame timing budgets. |
| Automotive Diagnostic Interface Multiplexing | Instrument Cluster Display Data Switching |
|
Use Scenario: Sharing a single diagnostic UART line among multiple ECUs (engine, transmission, ABS) via time-division access. IC Role / Device Role / Timing Role: Bidirectional signal gate controlled by microcontroller to route UART TX/RX between host and target ECU. Use Value: Eliminates need for discrete multiplexers; TTL-compatible inputs interface directly with UART peripherals without level translation. |
Use Scenario: Switching SPI data lines between main cluster MCU and secondary display driver IC during boot or fail-safe mode. IC Role / Device Role / Timing Role: Low-capacitance (≤6.45 pF off-state) analog switch preserving SPI signal rise/fall times up to 10 MHz. Use Value: Prevents signal reflections and crosstalk during mode transitions; 0.25 ns propagation delay avoids timing skew in display pixel clock domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual bus switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74CBT3306PWR | Commercial-grade (non-AEC-Q100), identical SO8 pinout and RON, but rated only to -40 °C to +85 °C without automotive qualification testing | Lacks AEC-Q100 Grade 3 stress testing and failure analysis reporting required for Tier 1 automotive programs | Select only for non-safety-critical industrial or consumer prototypes where automotive qualification is not mandated |
| TS3USB30E | Single-channel USB 2.0 switch with 6 Ω RON, integrated ESD protection (8 kV HBM), but no independent dual-channel OE control | Optimized for USB data lines only; lacks general-purpose bidirectional routing capability and dual independent enables | Prefer for dedicated USB signal isolation; avoid when independent control of two separate buses is required |
Compared with SN74CBT3306PWR and TS3USB30E, CBT3306PW-Q100 uniquely delivers AEC-Q100-compliant dual-channel isolation with per-channel enable control, making it the only option qualified for production automotive systems requiring both functional safety traceability and flexible bus segmentation.

FAQ
Is CBT3306PW-Q100 pin-compatible with CBT3306D-Q100?
Yes - both share identical SO8 (SOT96-1) package, pin assignment, and electrical specifications. The 'PW' suffix denotes tape-and-reel packaging per JEDEC J-STD-020, while 'D' indicates tube packaging; functionally interchangeable in PCB layout and schematic design.
What is the maximum continuous current per channel?
The absolute maximum output current is ±128 mA per channel, but recommended operating conditions specify ≤64 mA for guaranteed 5 Ω RON performance at VCC = 4.5 V. Sustained operation above 30 mA requires thermal validation per application PCB layout.
Does CBT3306PW-Q100 support level shifting between 3.3 V and 5 V domains?
No - it is not a level shifter. It operates only at its VCC supply voltage (4.5–5.5 V) and passes signals bidirectionally within that domain. Input thresholds are TTL-compatible but do not translate voltages; external level shifters are required for mixed-voltage interfacing.
How is latch-up protection verified for this device?
Latch-up immunity exceeds 100 mA per JESD78B Class II testing, confirmed through direct current injection at all pins while monitoring supply current and functional continuity. Test reports are available under NXP/Nexperia AEC-Q100 qualification documentation.
