Product details
Overview
74HC2G125DC-Q100 from Nexperia is a dual 3-state CMOS buffer/line driver qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 6.0 V and propagation delay as low as 8 ns at VCC = 6.0 V. It provides bidirectional signal buffering with independent active-low output enables (1OE, 2OE) and input clamp diodes enabling overvoltage-tolerant interfacing in body control modules and infotainment data buses.
For engineers reviewing the 74HC2G125DC-Q100 datasheet, 74HC2G125DC-Q100 pinout, 74HC2G125DC-Q100 application, or 74HC2G125DC-Q100 equivalent, key selection criteria include its VSSOP8 (SOT765-1) footprint, TTL-compatible variant (74HCT2G125DC-Q100), 3-state bus isolation capability, and AEC-Q100-compliant thermal and ESD performance across extended temperature ranges.
Technical Context
This device implements two independent non-inverting buffers, each with an active-low 3-state output enable (1OE, 2OE), allowing selective bus driving or high-impedance isolation. Input clamp diodes support current-limited interfacing to signals exceeding VCC, and logic thresholds are CMOS-level (VIH ≥ 0.7×VCC, VIL ≤ 0.3×VCC) for the HC version.
Dynamic behavior is characterized by matched propagation delays (tpd), enable (ten), and disable (tdis) times under defined load conditions (CL = 50 pF), with transition times (tt) as low as 5 ns at VCC = 6.0 V. Power dissipation capacitance (CPD = 11 pF enabled, 1 pF disabled) enables accurate dynamic power estimation per the provided formula.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters |
| Operating Temperature | -40 °C to +125 °C - qualified for engine bay and powertrain control unit environments |
| Propagation Delay | 8 ns max at VCC = 6.0 V, CL = 50 pF - ensures timing integrity in high-speed digital interconnects |
| Output Drive | ±7.8 mA at VCC = 4.5 V - sufficient to drive standard 50 pF loads with <0.4 V VOL / >3.7 V VOH margins |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive system-level robustness requirements |
| Input Clamp Diodes | Integrated - enables safe interface to voltages up to VCC + 0.5 V using external current-limiting resistors |

Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8 leads, 2.3 mm body width, 0.65 mm lead pitch, pin 1 indicator below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable for first buffer - drives 1Y high-impedance when HIGH |
| 2 | 1A | Data input for first buffer - directly connected to internal CMOS inverter stage |
| 3 | 1Y | Inverting-buffered output for first channel - driven LOW/HIGH or placed in Z-state per 1OE |
| 4 | GND | Ground reference for all I/O and internal circuitry - must be low-impedance connection |
| 5 | 2A | Data input for second buffer - electrically isolated from 1A; shares no internal nodes |
| 6 | 2Y | Inverting-buffered output for second channel - independently controllable via 2OE |
| 7 | 2OE | Active-low enable for second buffer - identical function and timing to 1OE |
| 8 | VCC | Positive supply rail - powers both buffers and enable logic; decoupling capacitor required |
Key Features

| SN74LVC2G125DBVR | Lower VCC range (1.65–5.5 V), higher drive (±24 mA), but only AEC-Q100 Grade 2 (−40 °C to +105 °C) | Suitable for cabin electronics but not under-hood applications requiring +125 °C operation | Use where higher drive or lower voltage operation is needed and Grade 1 temperature is not mandatory |
Compared with 74HC2G125DC-Q100, the 74HCT2G125DC-Q100 offers guaranteed TTL input compatibility at 5 V, while SN74LVC2G125DBVR trades AEC-Q100 Grade 1 compliance for wider voltage flexibility and stronger drive-making the HC variant optimal for new automotive designs prioritizing full temperature coverage and CMOS source compatibility.

FAQ
What is the maximum clock frequency supported by the 74HC2G125DC-Q100?
The 74HC2G125DC-Q100 is not a clocked device-it has no internal clock and operates asynchronously. Its usable data rate depends on propagation delay (8–23 ns) and load capacitance. With CL = 50 pF and VCC = 6.0 V, it reliably handles digital signals up to ~20 MHz for clean edge transitions, assuming proper PCB layout and termination.
Can 74HC2G125DC-Q100 drive a 100 pF load?
Yes, but with degraded timing: the datasheet specifies parameters at CL = 50 pF. At 100 pF, propagation delay increases approximately linearly-expect ~1.8× longer tpd (e.g., ~14 ns instead of 8 ns at VCC = 6.0 V). Output voltage margins remain valid, but ensure layout minimizes stray capacitance to maintain signal integrity.
Is there a pin-compatible LVCMOS alternative with lower supply voltage?
No pin-compatible AEC-Q100 Grade 1 alternative exists below 2.0 V VCC. The SN74LVC2G125DBVR supports 1.65–5.5 V but is only Grade 2 (−40 °C to +105 °C). For Grade 1 + low-voltage operation, redesign with level translators or dual-supply buffers is required-no drop-in replacement exists.
How does the input clamp diode affect interfacing with 12 V sensors?
The integrated clamp diodes allow safe connection to 12 V signals when used with a series current-limiting resistor (e.g., 10 kΩ limits IIK to <1.2 mA at 12 V). This avoids external protection components while ensuring VI stays within −0.5 V to VCC + 0.5 V-critical for reliability in automotive sensor front-ends.
