Product details
Overview
74AHCT2G125DP-Q10H from Nexperia is an automotive-qualified dual 3-state buffer/line driver with TTL-compatible inputs, operating from 4.5 V to 5.5 V supply, featuring symmetrical output impedance, balanced propagation delays (≤7.5 ns @ VCC=5 V, CL=50 pF), and overvoltage-tolerant inputs up to 5.5 V - used for bidirectional bus interfacing in engine control units and ADAS sensor hubs.
For engineers reviewing the 74AHCT2G125DP-Q10H datasheet, 74AHCT2G125DP-Q10H pinout, 74AHCT2G125DP-Q10H application, or 74AHCT2G125DP-Q10H equivalent, key selection criteria include TTL-level input compatibility, AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), TSSOP8 package thermal performance, and 3-state enable timing (ten ≤ 8.5 ns, tdis ≤ 10.0 ns).
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state output enable (1OE, 2OE). Input logic thresholds are fixed at VIH = 2.0 V min and VIL = 0.8 V max (TTL-compatible), enabling direct interface with legacy 5 V microcontrollers without level-shifting.
Propagation delay (tpd) and enable/disable timing are tightly matched between channels (Δtpd < 0.5 ns typical), supporting synchronized data routing in CAN/LIN transceiver interface circuits and automotive display serial buses where skew-sensitive signal integrity is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation across automotive battery rail variations including cold-crank (≥4.5 V) and load-dump (≤5.5 V) conditions. |
| Input Logic Type | TTL-compatible - accepts standard 5 V microcontroller outputs without external pull-ups or level translators. |
| Propagation Delay | ≤7.5 ns @ VCC = 5 V, CL = 50 pF - enables reliable 100+ MHz data throughput in high-speed sensor data aggregation paths. |
| Enable Time (ten) | ≤8.5 ns @ VCC = 5 V, CL = 50 pF - supports rapid bus arbitration cycles in multiplexed communication backplanes. |
| Disable Time (tdis) | ≤10.0 ns @ VCC = 5 V, CL = 50 pF - prevents bus contention during hot-swap or dynamic channel switching in modular ECUs. |
| Output Drive | ±8 mA @ VCC = 5 V - sufficient to drive 50 pF loads over 10 cm PCB traces without signal degradation. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for powertrain and chassis applications per automotive reliability requirements. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.65 mm pitch, 0.5 mm lead length - optimized for automated SMT assembly and thermal dissipation in dense automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 | 1OE, 2OE | Active-low 3-state enable inputs - asserted LOW to enable respective buffer output; HIGH places output in high-impedance state for bus sharing. |
| 2, 5 | 1A, 2A | Data inputs - TTL-level compatible; overvoltage tolerant to 5.5 V, allowing safe interfacing with mixed-voltage subsystems. |
| 3, 6 | 1Y, 2Y | Buffered non-inverting outputs - deliver rail-to-rail CMOS swing with symmetrical rise/fall times for minimal jitter in clock/data distribution. |
| 4 | GND | Ground reference - dedicated low-inductance return path; must be connected to solid ground plane to maintain noise immunity. |
| 8 | VCC | Power supply - decoupling capacitor (100 nF X7R) required within 3 mm of this pin to suppress switching noise and ensure stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| TTL input compatibility | VIH ≥ 2.0 V, VIL ≤ 0.8 V - eliminates need for external level shifters when interfacing with legacy 5 V MCU GPIOs. |
| Overvoltage-tolerant inputs | Withstand 5.5 V regardless of VCC - enables safe connection to higher-voltage domains (e.g., 5 V sensor lines) without clamping diodes. |
| Symmetrical output impedance | Matched pull-up/pull-down strength - ensures equal rise/fall times (<1 ns skew) critical for clean signal edges in high-speed buses. |
| Balanced propagation delays | Channel-to-channel tpd mismatch < 0.5 ns - maintains timing alignment across dual-buffered signals in time-critical control loops. |
| Low ICC quiescent current | ≤40 μA @ VCC = 5.5 V - reduces standby power in always-on automotive modules such as telematics wake-up receivers. |
Applications
| Engine Control Unit (ECU) Bus Interface | ADAS Camera Sensor Hub |

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 |
|---|---|---|---|
| 74AHCT2G125DC-Q100 | VSSOP8 package (2.3 mm width), lower thermal resistance (4.9 mW/K derating above 99 °C), identical electrical specs. | Better suited for ultra-dense layouts where board space is constrained, but requires tighter placement tolerance during reflow. | Select when footprint area is prioritized over thermal margin and hand-soldering serviceability. |
| SN74LVC2G125QDCURQ1 | Wider VCC range (1.65–5.5 V), CMOS input thresholds, lower ICC (≤10 μA), same AEC-Q100 Grade 1 rating. | Enables single-supply operation with 3.3 V MCUs; not TTL-compatible - requires redesign if interfacing with 5 V logic. | Select only when migrating to 3.3 V systems and full TTL compatibility is not required. |
Compared with 74AHCT2G125DP-Q10H, the DC variant offers smaller footprint at the cost of reduced thermal headroom, while the TI part enables lower-voltage operation but sacrifices direct 5 V TTL interoperability - choice depends strictly on layout density constraints and system voltage architecture.

FAQ
Is 74AHCT2G125DP-Q10H pin-compatible with 74AHC2G125DP-Q100?
Yes - both share identical TSSOP8 (SOT505-2) pinout and mechanical footprint. However, input thresholds differ: AHCT uses TTL levels (VIH ≥ 2.0 V), while AHC uses CMOS levels (VIH ≥ 0.7×VCC). Interchange requires verification of source driver compatibility.
What is the maximum capacitive load this device can drive reliably?
It is characterized up to 50 pF load capacitance with guaranteed timing (tpd ≤ 7.5 ns, ten ≤ 8.5 ns at VCC = 5 V). Driving >50 pF may increase propagation delay and degrade edge monotonicity; use series termination or buffer staging for heavier loads.
Does this device require external pull-up resistors on OE pins?
No - OE inputs are active-low CMOS/TTL compatible with standard logic levels. When left unconnected, internal leakage ensures default HIGH state (outputs disabled); however, for deterministic behavior in noisy environments, tie OE to VCC via 10 kΩ resistor.
Can 74AHCT2G125DP-Q10H operate at 3.3 V supply?
No - the AHCT version is specified only for 4.5 V to 5.5 V operation. At 3.3 V, VIH threshold (2.0 V) exceeds 60% of VCC, risking unreliable HIGH recognition. Use 74LVC2G125 variants for 3.3 V systems.
