Product details
Overview
74AHC2G125DP-Q100 from Nexperia is an automotive-qualified dual CMOS buffer/line driver with 3-state outputs, designed for voltage-level translation in mixed-voltage systems (2.0 V to 5.5 V supply), featuring overvoltage-tolerant inputs up to 5.5 V and AEC-Q100 Grade 1 qualification for operation from −40 °C to +125 °C. It serves as a bidirectional signal isolator in CAN/LIN interface subcircuits and body control modules.
For engineers reviewing the 74AHC2G125DP-Q100 datasheet, 74AHC2G125DP-Q100 pinout, 74AHC2G125DP-Q100 application, or 74AHC2G125DP-Q100 equivalent, key selection criteria include 3-state enable timing (ten ≤ 9.5 ns at VCC = 5 V), symmetrical output impedance, balanced propagation delays (tpd ≤ 7.5 ns), and input level compatibility with both CMOS and TTL logic families.
Technical Context
This device implements two independent non-inverting buffers, each controlled by a dedicated active-low 3-state enable input (1OE, 2OE). Its overvoltage-tolerant inputs allow interfacing between 3.3 V logic domains and 5 V buses without external level shifters.
The architecture supports simultaneous high-impedance output states during enable transitions, minimizing bus contention in multiplexed automotive data lines. Propagation delay symmetry (tPLH ≈ tPHL) and matched enable/disable timing (tPZH ≈ tPHZ) ensure deterministic signal integrity in time-critical control paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - enables direct integration into 3.3 V and 5 V automotive subsystems without regulators. |
| Operating Temperature | −40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood and powertrain applications. |
| Propagation Delay | ≤ 7.5 ns at VCC = 5 V, CL = 50 pF - ensures sub-10 ns signal routing for real-time sensor data forwarding. |
| Enable Time (ten) | ≤ 9.5 ns at VCC = 5 V, CL = 50 pF - guarantees fast bus arbitration response in multi-node LIN networks. |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - permits safe connection to higher-voltage peripherals without clamping diodes. |
| Output Drive Strength | ±8 mA at VCC = 4.5 V - sufficient to drive 50 pF loads across 10 cm PCB traces in ECU backplanes. |
| Static Supply Current | ≤ 40 μA at VCC = 5.5 V - supports low-quiescent-power sleep modes in always-on vehicle networks. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.65 mm lead pitch, 0.5 mm lead length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 (1OE, 2OE) | Active-low 3-state enable | Drives corresponding output (1Y or 2Y) into high-impedance when LOW; enables buffer when HIGH. |
| 2, 5 (1A, 2A) | Data input | CMOS-compatible input accepting voltages up to 5.5 V independent of VCC. |
| 3, 6 (2Y, 1Y) | Data output | Non-inverting buffered output with ±8 mA drive capability and 3-state control. |
| 4 | GND | Reference ground for all I/O and supply terminals; must be low-inductance connection in automotive layouts. |
| 8 | VCC | Primary power supply rail; decoupling capacitor (100 nF) required within 5 mm per JEDEC guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V signals regardless of VCC setting, eliminating need for external level translators in mixed-voltage domains. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduced signal distortion on shared buses. |
| Balanced propagation delays | tPLH and tPHL differ by ≤ 0.5 ns at 5 V, critical for maintaining setup/hold timing in synchronous data capture. |
| ESD robustness | HBM > 2000 V and CDM > 1000 V - exceeds automotive ESD immunity requirements for assembly and field operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT2G125DP-Q100 | TTL-compatible inputs (VIL ≤ 0.8 V, VIH ≥ 2.0 V) vs. CMOS inputs (VIL ≤ 1.65 V, VIH ≥ 3.85 V at 5.5 V) | Required where legacy 5 V TTL microcontrollers drive the buffer without pull-ups | Select when interfacing with older 5 V logic families; otherwise prefer AHC version for lower static power |
| SN74LVC2G125DBVR | Wider temperature range (−40 °C to +125 °C) but not AEC-Q100 qualified; lower drive (±24 mA) and faster tpd (3.7 ns) | Suitable for industrial or consumer designs lacking automotive qualification requirements | Use only in non-automotive contexts; lacks AEC-Q100 documentation and stress-test validation |
Compared with 74AHCT2G125DP-Q100, the AHC variant offers superior noise immunity and lower ICC at 3.3 V operation, while SN74LVC2G125DBVR trades automotive reliability for higher speed and drive strength in commercial environments.

FAQ
What is the maximum input voltage the 74AHC2G125DP-Q100 can tolerate?
The device accepts input voltages up to 5.5 V regardless of VCC level, enabling safe interfacing with 5 V peripherals even when powered from 3.3 V. This overvoltage tolerance eliminates external clamping circuits and simplifies mixed-voltage board design in automotive ECUs.
Does this part support hot-swap insertion on live 5 V buses?
Yes - its overvoltage-tolerant inputs and 3-state outputs prevent bus contention during insertion. When 1OE/2OE are held LOW during power-up, outputs remain in high-impedance until VCC stabilizes, avoiding glitches on shared data lines like LIN or SENT.
How does the 74AHC2G125DP-Q100 differ from standard 74AHC2G125 variants?
It features full AEC-Q100 Grade 1 qualification (−40 °C to +125 °C), enhanced ESD protection (HBM > 2000 V), and extended lifetime reliability testing per automotive standards - unlike commercial-grade versions which lack stress validation for under-hood deployment.
Can both buffers operate independently with different enable signals?
Yes - pins 1 (1OE) and 7 (2OE) provide separate active-low controls for each buffer channel. This allows asynchronous gating of two signal paths, such as enabling sensor data transmission while disabling diagnostic LED drivers during sleep mode.
