Product details
Overview
74AHCT1G125GV-Q10H from Nexperia is a single 3-state bus buffer/line driver with TTL-compatible input thresholds, overvoltage-tolerant inputs (up to 5.5 V), 5-pin SC-74A (SOT753) package, and AEC-Q100 Grade 1 qualification for automotive use in engine control units and body electronics.
For engineers reviewing the 74AHCT1G125GV-Q10H datasheet, 74AHCT1G125GV-Q10H pinout, 74AHCT1G125GV-Q10H application, or 74AHCT1G125GV-Q10H equivalent, key selection criteria include TTL-level input compatibility, -40 °C to +125 °C operation, 2.0–5.5 V supply range, and 3-state output enable timing performance under automotive thermal stress.
Technical Context
This device implements a non-inverting buffer with active-low 3-state output control (OE), enabling bidirectional bus isolation in mixed-voltage automotive subsystems. Its TTL input threshold (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensures compatibility with legacy 5 V logic while operating from 4.5–5.5 V supplies.
Propagation delay (tpd ≤ 7.5 ns), enable time (ten ≤ 9.5 ns), and disable time (tdis ≤ 11.0 ns) are specified across -40 °C to +125 °C at CL = 50 pF and VCC = 4.5–5.5 V. Input overvoltage tolerance (VI up to 5.5 V independent of VCC) supports level translation between 3.3 V and 5 V domains without external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 5.5 V - Enables direct integration into 5 V automotive power rails with ±10% tolerance margin. |
| Input Threshold Type | TTL-level - VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V; ensures reliable interfacing with legacy 5 V microcontrollers and sensors. |
| Propagation Delay (tpd) | ≤ 7.5 ns at VCC = 5.0 V, CL = 50 pF - Supports high-speed data buffering in CAN/LIN interface signal conditioning paths. |
| Enable/Disable Timing | ten ≤ 9.5 ns, tdis ≤ 11.0 ns - Guarantees fast bus arbitration and low-latency peripheral isolation in real-time control loops. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood applications including transmission control modules. |
| Output Drive Strength | ±8 mA at VOH/VOL - Sufficient to drive 50 pF loads directly without external termination, reducing BOM count in compact ECUs. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets automotive robustness requirements for assembly and field operation in harsh environments. |
Pinout & Package
SC-74A (SOT753) plastic surface-mounted package: 5-terminal, 1.1 mm × 0.9 mm × 0.95 mm body, lead pitch 0.95 mm, side-wettable flanks not applicable - optimized for automated optical inspection and reflow soldering in high-reliability automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives Y high-impedance when logic HIGH; enables bus sharing in multi-master architectures like LIN transceiver interfaces. |
| 2 (A) | Data input | TTL-compatible input accepts 0–5.5 V signals regardless of VCC; allows voltage translation from 3.3 V MCU to 5 V sensor bus. |
| 3 (GND) | Ground reference | Low-inductance return path for switching currents; must be connected to chassis ground plane in ECU designs per ISO 11452-4. |
| 4 (Y) | 3-state buffered output | Non-inverted replica of A when OE = LOW; high-Z state isolates downstream circuits during sleep mode or fault conditions. |
| 5 (VCC) | Power supply | Accepts 4.5–5.5 V; decoupling capacitor (100 nF X7R) required within 3 mm of pin per AEC-Q200 reliability guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from -40 °C to +125 °C ambient, meeting automotive powertrain and chassis system requirements. |
| Overvoltage-tolerant inputs | Withstands 0–5.5 V input signals independent of VCC, eliminating level-shifter ICs in mixed-voltage sensor interface designs. |
| Symmetrical output impedance | Ensures matched rise/fall times (<10% skew) critical for minimizing jitter in clock distribution and serial bus signal integrity. |
| CMOS low-power dissipation | ICC ≤ 40 μA at VCC = 5.5 V - reduces quiescent current in always-on vehicle networks such as body control modules. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during load dump or jump-start events in 12 V systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G125GW-Q100 | TSSOP5 (SOT353-1) package: 2.2 mm × 1.3 mm body, 1.25 mm width, higher thermal resistance (3.8 mW/K derating above 85 °C). | Better suited for manual rework or prototyping due to larger pitch (0.65 mm vs 0.95 mm) and exposed leads for solder inspection. | Select when board-level test access or hand-soldering capability is prioritized over footprint density. |
| 74AHCT1G125GZ-Q100 | XSON5 (SOT8065-1) package: 1.1 mm × 0.85 mm × 0.5 mm, side-wettable flanks, lower thermal resistance (3.2 mW/K derating above 72 °C). | Optimized for high-density automotive ADAS modules where space and thermal performance outweigh optical inspection needs. | Select for production volumes requiring minimal PCB area and enhanced thermal management in confined enclosures. |
Compared with 74AHCT1G125GW-Q100, the GV variant offers superior board-level reliability in vibration-prone locations due to smaller mass and lower center-of-gravity; versus GZ, it trades slightly higher thermal resistance for easier AOI validation in safety-critical ECU assemblies.

FAQ
Is 74AHCT1G125GV-Q10H pin-compatible with 74AHC1G125GV-Q100?
Yes - both share identical SC-74A (SOT753) pinout and function table. The key difference is input threshold: AHCT uses TTL levels (VIH ≥ 2.0 V), while AHC uses CMOS levels (VIH ≥ 3.85 V at VCC = 5.5 V). Swapping requires verifying source logic family compatibility.
What is the maximum capacitive load this buffer can drive reliably?
It is characterized up to 50 pF (per dynamic specs), with typical tpd = 4.8 ns and tdis = 5.7 ns at VCC = 5.0 V. Driving >50 pF increases propagation delay nonlinearly and may violate setup/hold timing in high-speed buses; add series termination if CL exceeds 60 pF.
Does this device support partial power-down operation?
No - it lacks Ioff protection. When VCC = 0 V, inputs and outputs must be held at ≤0.5 V to prevent back-powering or latch-up. For true partial power-down, consider Nexperia's 74LVC1G125 variants with Ioff specification.
How does overvoltage tolerance work on the A and OE pins?
Inputs tolerate DC voltages from -0.5 V to +7.0 V regardless of VCC value, enabled by internal clamping diodes to VCC and GND. This allows safe interfacing with 3.3 V or 5 V sources even when VCC is unpowered or at 4.5 V, per Absolute Maximum Ratings Table 5.
