Product details
Overview
74AHCT1G125GW-Q10H from Nexperia is an automotive-qualified single 3-state bus buffer/line driver with TTL-compatible inputs, 2.0–5.5 V supply range, -40 °C to +125 °C operation, and overvoltage-tolerant inputs up to 5.5 V. It serves as a level-translating interface in CAN/LIN subsystems, sensor signal conditioning paths, and microcontroller I/O expansion circuits.
For engineers reviewing the 74AHCT1G125GW-Q10H datasheet, 74AHCT1G125GW-Q10H pinout, 74AHCT1G125GW-Q10H application, or 74AHCT1G125GW-Q10H equivalent, this page delivers verified functional behavior, automotive-grade thermal and ESD specs, TSSOP5 package layout, and direct substitution guidance for AEC-Q100 Grade 1 designs.
Technical Context
This device implements a non-inverting 3-state buffer with active-low output enable (OE), enabling bidirectional bus control in automotive communication interfaces. Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure compatibility with legacy 5 V logic while operating from 4.5–5.5 V supplies.
Propagation delay is specified at 3.4–5.5 ns (typ/max) under 5 V/15 pF conditions, with matched enable/disable timing (ten = 3.9–5.1 ns, tdis = 4.5–6.1 ns). Input overvoltage tolerance to 5.5 V allows safe interfacing between mixed-voltage domains without external clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 5.5 V - supports stable operation across automotive battery transients (e.g., load dump, cold crank). |
| Input Logic Type | TTL-compatible - accepts standard 5 V TTL input levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V), not CMOS thresholds. |
| Output Drive Strength | ±8 mA at VCC = 4.5 V - sufficient to drive 15–50 pF loads typical in CAN/LIN stub lines and MCU GPIO expansion. |
| Propagation Delay (tpd) | 3.4 ns (typ) / 5.5 ns (max) at VCC = 5.0 V, CL = 15 pF - enables sub-100 MHz digital timing margins in body control modules. |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for powertrain, chassis, and ADAS ambient zones per automotive reliability standard. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive board-level ESD robustness requirements without external protection. |
| Input Overvoltage Tolerance | 5.5 V absolute max - permits safe connection to 5 V buses even when VCC is powered down or at 3.3 V. |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives Y high-impedance when low; enables buffer pass-through when high - used for bus arbitration and power-gated I/O control. |
| 2 (A) | Data input | TTL-level input accepting 0–5.5 V swing; tolerant of overvoltage during hot-swap or partial-power conditions. |
| 3 (GND) | Ground reference | 0 V return path for all internal logic and output current; must be low-inductance connection in automotive PCB layouts. |
| 4 (Y) | 3-state buffered output | Non-inverting output with ±8 mA drive; enters high-Z state within 6.1 ns (max) of OE deassertion - prevents bus contention. |
| 5 (VCC) | Positive supply | 4.5–5.5 V nominal supply; decoupling capacitor (100 nF ceramic) required within 5 mm for EMC compliance in vehicle harnesses. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from −40 °C to +125 °C ambient - suitable for engine bay and transmission control units. |
| Overvoltage-tolerant inputs | Withstands 5.5 V input regardless of VCC state - eliminates need for external level shifters when interfacing 5 V sensors to 3.3 V MCUs. |
| Symmetrical output impedance | Matched rise/fall times (tpLH ≈ tpHL) and VOH/VOL balance - reduces signal distortion on stubbed CAN/LIN bus traces. |
| Low dynamic power dissipation | CPD = 11 pF - limits switching current in high-frequency enable/disable cycling common in diagnostic communication protocols. |
| High noise immunity | CMOS process with > 40 % noise margin at VCC = 5 V - resists coupled transients from ignition systems and motor drives. |

FAQ
What is the maximum input voltage the 74AHCT1G125GW-Q10H can tolerate when VCC = 3.3 V?
The device supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level. When VCC = 3.3 V, inputs may safely reach 5.5 V without damage or latch-up, enabling direct interface with 5 V sensors or legacy peripherals without external clamping diodes or level shifters.
Does the 74AHCT1G125GW-Q10H support hot-swap operation?
Yes - its overvoltage-tolerant inputs and guaranteed high-impedance OFF-state (IOZ ≤ 10 μA at VCC = 5.5 V) allow safe insertion into live 5 V buses. The 3-state output remains isolated until OE is asserted, preventing back-driving or bus contention during connector mating.
How does the propagation delay vary across temperature and voltage?
At VCC = 5.0 V and CL = 15 pF, tpd ranges from 3.4 ns (typ) at 25 °C to 7.0 ns (max) at +125 °C ambient. This monotonic increase is characterized per Table 8 and ensures timing predictability in engine control units where junction temperature exceeds 100 °C.
Can the 74AHCT1G125GW-Q10H replace the 74AHC1G125GW-Q100 in existing designs?
No - the 74AHCT1G125GW-Q10H has TTL input thresholds (VIH = 2.0 V min), while the 74AHC1G125GW-Q100 uses CMOS thresholds (VIH = 3.85 V min at VCC = 5.5 V). Swapping requires verification that driving sources meet the respective input voltage requirements to avoid logic misreads.
