Product details
Overview
74VHC126PW-Q100 from Nexperia is a quad non-inverting 3-state buffer/line driver with CMOS input levels, AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), 5.5 V max supply voltage, and propagation delay as low as 3.3 ns (VCC = 4.5–5.5 V, CL = 15 pF). It serves as a level-shifting and bus-isolation interface in automotive infotainment data buses.
For engineers reviewing the 74VHC126PW-Q100 datasheet, 74VHC126PW-Q100 pinout, 74VHC126PW-Q100 application, or 74VHC126PW-Q100 equivalent, this page delivers verified pin functions, automotive-grade thermal and ESD specs, real-world timing behavior under load, and direct substitution guidance for CAN/LIN subsystem interconnects.
Technical Context
This device implements four independent non-inverting buffers, each with an active-HIGH output enable (nOE) controlling high-impedance (Z) state on the corresponding nY output. All inputs feature Schmitt-trigger action and tolerate voltages up to 7.0 V - exceeding VCC - enabling robust noise immunity in noisy automotive environments.
It operates across two logic families: the 74VHC126 variant accepts CMOS-level inputs (VIH ≥ 3.85 V at VCC = 5.5 V), while its pin-compatible 74VHCT126 sibling supports TTL-level inputs (VIH ≥ 2.0 V). Both share identical 3-state output architecture, propagation delay profiles, and AEC-Q100 qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 2.0 V to 5.5 V - supports 3.3 V and 5 V automotive domains without level shifters. |
| Propagation Delay (tpd) | 3.3 ns typical (VCC = 4.5–5.5 V, CL = 15 pF) - enables reliable 100+ MHz bus signaling with margin. |
| Output Drive | ±8.0 mA (VOH/VOL @ VCC = 4.5 V) - sufficient to drive 50 pF loads across PCB traces and connectors. |
| Input Voltage Tolerance | −0.5 V to +7.0 V - withstands load-dump transients and I/O overvoltage without clamping diode conduction. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive system-level ESD robustness requirements per ISO 10605. |
| Ambient Temp Range | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and ADAS ECU placement. |
| Power Dissipation (Ptot) | 500 mW max (Tamb ≤ 125 °C); derates 7.3 mW/K above 81 °C - matches TSSOP14 thermal profile for sustained operation. |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1), 14-lead, body width 4.4 mm, 0.65 mm pitch, exposed pad optional - optimized for automated optical inspection (AOI) and high-density automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (1OE–4OE) | Output Enable Input | Active-HIGH control per channel; drives respective nY into high-Z when LOW - enables time-multiplexed bus sharing. |
| 2, 5, 9, 12 (1A–4A) | Data Input | CMOS-compatible input with Schmitt-trigger hysteresis (typ. 0.3 V) - rejects <10 ns noise spikes on long harness lines. |
| 3, 6, 8, 11 (1Y–4Y) | Data Output | 3-state buffered output; sinks/sours ±8 mA; VOL ≤ 0.36 V @ 8 mA ensures clean logic LOW under worst-case load. |
| 7 | GND | Ground reference for all I/O and internal circuitry; must be low-inductance connection to minimize ground bounce. |
| 14 | VCC | Primary power supply; decoupling capacitor (100 nF ceramic) required within 5 mm of pin for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with lifetime reliability testing - suitable for powertrain and ADAS ECUs. |
| Input overvoltage tolerance | Accepts up to +7.0 V regardless of VCC - eliminates need for external clamping in 12 V system interfaces. |
| Low dynamic power | CPD = 10 pF - reduces switching current and heat generation in high-frequency bus applications. |
| Matched propagation delays | Typical tPHL/tPLH variation < 0.5 ns across channels - ensures deterministic skew for parallel data paths. |
| Side-wettable flanks (SWF) | Available in DHVQFN variant (BQ); not present in PW - enables AOI of solder joints for zero-defect automotive assembly. |
Applications
| Infotainment Display Interface | Body Control Module (BCM) Signal Routing |
|---|---|
|
Use Scenario: Isolating display data bus between MCU and TFT controller during sleep mode to reduce leakage current. IC Role / Device Role / Timing Role: 3-state buffer enabling bidirectional bus hold-off; enables fast enable/disable (<7 ns ten) synchronized with display power sequencing. Use Value: Eliminates cross-talk between active and idle subsystems; maintains signal integrity with <0.5 ns inter-channel skew. |
Use Scenario: Level-shifting and buffering LIN bus signals between 3.3 V microcontroller and 12 V transceiver. IC Role / Device Role / Timing Role: Non-inverting line driver with TTL-compatible input (74VHCT126 variant); provides noise-immune signal regeneration. Use Value: Schmitt-trigger inputs reject harness-induced noise; ±8 mA drive sustains LIN waveform shape over 20 m cable runs. |
| ADAS Camera Sensor Interface | Electric Power Steering (EPS) Diagnostic Bus |
|
Use Scenario: Buffering parallel pixel clock and data lines from image sensor to SoC in compact camera module. IC Role / Device Role / Timing Role: Quad channel timing-critical buffer; operates at 3.3 V with sub-5 ns tpd to meet MIPI D-PHY timing budgets. Use Value: Low 10 pF input capacitance minimizes loading on high-speed sensor outputs; TSSOP14 footprint fits tight space constraints. |
Use Scenario: Enabling/disabling diagnostic communication path between EPS ECU and service tool via dedicated UART line. IC Role / Device Role / Timing Role: Single-channel 3-state gate controlled by ECU firmware; isolates diagnostic port when not in use. Use Value: High-impedance OFF-state (IOZ ≤ ±0.25 μA) prevents backfeeding into service tool; AEC-Q100 ensures reliability during roadside diagnostics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74VHCT126PW-Q100 | TTL-input compatible (VIH = 2.0 V min); otherwise identical pinout, timing, and packaging. | Required where upstream logic uses 5 V TTL outputs (e.g., legacy microcontrollers, discrete logic). | Select when interfacing with 5 V LSTTL sources; retains same AEC-Q100 qualification and thermal specs. |
| SN74LVC126AQPWRQ1 | Lower VCC range (1.65–3.6 V); 3.3 V-only operation; higher drive (±24 mA); different pinout (SOIC-14 only). | Suitable for 3.3 V-only domains (e.g., domain controllers), but not drop-in for 5 V systems or TSSOP layout. | Choose only if system is strictly 3.3 V and higher drive is needed; requires PCB redesign due to pin mismatch. |
Compared with 74VHC126PW-Q100, the 74VHCT126PW-Q100 offers seamless integration with legacy 5 V TTL logic, while SN74LVC126AQPWRQ1 trades 5 V compatibility for enhanced 3.3 V drive strength - making the original part optimal for mixed-voltage automotive buses requiring robust overvoltage tolerance and pin-for-pin upgrade path.

FAQ
What is the maximum operating frequency supported by the 74VHC126PW-Q100?
The device does not specify a maximum clock frequency directly, but its propagation delay (tpd ≤ 7.0 ns at VCC = 4.5–5.5 V, CL = 50 pF) and enable/disable times (ten/tdis ≤ 9.5 ns) support reliable operation up to ~100 MHz for single-edge data transmission. System-level timing must account for board trace capacitance and load conditions.
Can the 74VHC126PW-Q100 interface directly with 5 V TTL outputs?
No - the 74VHC126PW-Q100 requires CMOS-level inputs (VIH ≥ 3.85 V at VCC = 5.5 V), whereas standard 5 V TTL outputs swing only to ~3.5 V. For TTL compatibility, use the pin-compatible 74VHCT126PW-Q100 variant, which guarantees VIH ≥ 2.0 V and VIL ≤ 0.8 V.
Does this device require external pull-up or pull-down resistors on unused inputs?
Unused inputs should be terminated to VCC or GND - not left floating - to prevent increased ICC and potential oscillation. The Schmitt-trigger inputs reduce sensitivity to slow edges, but static biasing remains mandatory per JEDEC standards and AEC-Q100 reliability requirements.
Is the TSSOP14 package (SOT402-1) lead-free and RoHS compliant?
Yes - the 74VHC126PW-Q100 is manufactured in full compliance with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Nexperia confirms lead-free terminations and halogen-free molding compound; full material declarations are available upon request.
