Product details
Overview
74AHC125PW-Q100 from Nexperia is an automotive-qualified quad buffer/line driver with 3-state outputs, designed for voltage-level translation in mixed-voltage automotive subsystems. It operates from 2.0 V to 5.5 V, features overvoltage-tolerant inputs up to 5.5 V, supports -40 °C to +125 °C ambient range, and delivers propagation delay as low as 3.0 ns (VCC = 5.0 V, CL = 15 pF). It is used in body control modules for isolating I²C or GPIO signal paths between 3.3 V microcontrollers and 5 V sensor interfaces.
For engineers reviewing the 74AHC125PW-Q100 datasheet, 74AHC125PW-Q100 pinout, 74AHC125PW-Q100 application, or 74AHC125PW-Q100 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification, CMOS input compatibility, 3-state enable timing (ten ≤ 7.0 ns), and TSSOP14 package suitability for space-constrained PCB layouts in ADAS domain controllers and infotainment gateways.
Technical Context
This device implements four independent non-inverting buffers, each with active-low 3-state output enable (nOE) controlling high-impedance output states. Its Schmitt-trigger inputs provide noise immunity against slow-rising signals on shared bus lines, while overvoltage tolerance enables safe interfacing between 3.3 V logic domains and legacy 5 V peripherals without external level shifters.
All four channels share a common supply rail (VCC) and ground (GND), with no internal power sequencing requirements. The logic function follows standard truth table behavior: when nOE = LOW, output Y mirrors input A; when nOE = HIGH, output Y enters high-impedance state regardless of A. Input thresholds are CMOS-compatible (VIH ≥ 3.85 V at VCC = 5.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - Enables direct operation across 3.3 V and 5 V automotive domains without regulators. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood and transmission control unit environments. |
| Propagation Delay | 3.0 ns (typ, VCC = 5.0 V, CL = 15 pF) - Supports >100 MHz data rates in buffered clock distribution paths. |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - Allows safe connection to 5 V buses while powered from 3.3 V rails. |
| Output Drive Strength | ±8.0 mA (VOH/VOL @ VCC = 4.5 V) - Sufficient to drive 15 pF loads with <0.55 V VOL under full load. |
| Quiescent Current | 2.0 μA (typ, VCC = 5.5 V) - Minimizes standby power in always-on vehicle networks like LIN or CAN wake-up circuits. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets automotive board-level ESD robustness requirements per ISO 10605. |
Pinout & Package
TSSOP14 plastic thin shrink small outline package (SOT402-1); 14 leads; body width 4.4 mm; 0.65 mm pitch; exposed pad optional for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (1OE–4OE) | Active-low output enable | Independent control per channel; HIGH forces high-impedance output, enabling bus sharing. |
| 2, 5, 9, 12 (1A–4A) | Data input | CMOS-compatible inputs with Schmitt-trigger action for noise rejection on long traces. |
| 3, 6, 8, 11 (1Y–4Y) | Buffered output | Non-inverting output with 3-state capability; drives capacitive loads up to 50 pF. |
| 7 (GND) | Ground reference | Single ground pin for all four channels; requires low-inductance PCB connection. |
| 14 (VCC) | Supply voltage | Single supply rail powers all logic and output stages; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling and HTOL stress. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals irrespective of VCC setting - eliminates need for external clamping diodes. |
| Low dynamic power dissipation | CPD = 10 pF - reduces switching current in high-frequency GPIO buffering applications. |
| Schmitt-trigger inputs | Hysteresis ≥ 0.5 V (typ) - rejects noise on noisy chassis-ground-referenced signal lines. |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints in TSSOP14 package - improves manufacturing yield. |
Applications
| Body Control Module (BCM) | Advanced Driver Assistance Systems (ADAS) |
|---|---|
|
Use Scenario: Isolating microcontroller GPIOs from 5 V lamp drivers and relay coils in centralized BCM units. IC Role / Device Role / Timing Role: Quad buffer provides galvanic isolation and level translation between 3.3 V MCU and 5 V actuator interface, with 3-state control enabling shared diagnostic bus access. Use Value: Eliminates discrete level-shifter ICs and reduces BOM count by consolidating four independent buffers into one AEC-Q100-compliant package. |
Use Scenario: Buffering camera sensor sync signals and I²C configuration lines in surround-view processing units. IC Role / Device Role / Timing Role: Provides low-skew, low-jitter signal routing between SoC and image sensors while maintaining signal integrity across mixed-voltage domains. Use Value: Propagation delay variation ≤ 1.5 ns between channels ensures precise timing alignment critical for multi-camera frame synchronization. |
| Infotainment Gateway | Electric Power Steering (EPS) |
|
Use Scenario: Managing communication handshaking between head-unit MCU and Bluetooth/Wi-Fi module reset and interrupt lines. IC Role / Device Role / Timing Role: Acts as bidirectional signal conditioner with 3-state outputs allowing shared interrupt line arbitration between multiple peripherals. Use Value: Overvoltage-tolerant inputs prevent latch-up during hot-plug events when modules power up asynchronously. |
Use Scenario: Interfacing torque sensor analog conditioning circuitry with EPS ECU's ADC reference and digital status lines. IC Role / Device Role / Timing Role: Buffers safety-critical status flags (e.g., sensor fault, watchdog timeout) with fail-safe high-impedance default state. Use Value: Latch-up immunity >100 mA ensures resilience against transient faults in high-noise motor-drive environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT125PW-Q100 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and packaging. | Better suited for interfacing with legacy 5 V TTL logic; higher input current draw vs. AHC version. | Select when driving from older 5 V microcontrollers or FPGAs with TTL output levels. |
| SN74LVC125APWRE4 | Lower VCC range (1.65–3.6 V), non-automotive grade, same TSSOP14 footprint but not AEC-Q100 qualified. | Limited to cabin electronics with <85 °C ambient; unsuitable for powertrain or chassis systems. | Use only in cost-sensitive, non-safety-critical interior modules where automotive qualification is waived. |
Compared with 74AHCT125PW-Q100, the 74AHC125PW-Q100 offers lower static current and CMOS input thresholds ideal for modern low-power MCUs; versus SN74LVC125APWRE4, it trades wider voltage range and AEC-Q100 compliance for slightly higher quiescent power.

FAQ
Is the 74AHC125PW-Q100 pin-compatible with standard 74AHC125 variants?
Yes - the 74AHC125PW-Q100 shares identical pinout, electrical characteristics, and functional behavior with non-automotive 74AHC125 TSSOP14 variants. However, it includes enhanced process controls, extended temperature validation (-40 °C to +125 °C), and full AEC-Q100 Grade 1 qualification documentation required for automotive deployment.
Can this device be used to translate between 1.8 V and 3.3 V logic domains?
No - the 74AHC125PW-Q100 requires VCC ≥ 2.0 V and does not support 1.8 V operation. Its inputs are overvoltage tolerant up to 5.5 V but are not designed for sub-2.0 V supply rails. For 1.8 V ↔ 3.3 V translation, consider dedicated level translators such as TXB0104 or NTS0104.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 50 pF load capacitance with guaranteed timing (tpd ≤ 9.5 ns at VCC = 5.0 V). Driving >50 pF may increase propagation delay and output rise/fall times beyond specification; for heavier loads, add series termination or use a dedicated line driver with higher drive strength.
Does the TSSOP14 package require soldering the exposed thermal pad?
No - the TSSOP14 (SOT402-1) package for 74AHC125PW-Q100 does not include an exposed thermal pad. Only the DHVQFN14 (SOT762-1) variant features a thermal pad; the TSSOP version relies on lead-frame conduction and PCB copper area for thermal management.
