Product details
Overview
74AHC2G125DC-Q100 from Nexperia is an automotive-qualified dual CMOS buffer/line driver with 3-state outputs, controlled by independent active-low enable inputs (1OE, 2OE). It operates from 2.0 V to 5.5 V, features overvoltage-tolerant inputs up to 5.5 V, and delivers symmetrical output impedance and balanced propagation delays (typ. 3.4 ns at 5 V, 15 pF). It is used in automotive body control modules for bidirectional signal isolation between mixed-voltage sub-systems.
For engineers reviewing the 74AHC2G125DC-Q100 datasheet, 74AHC2G125DC-Q100 pinout, 74AHC2G125DC-Q100 application, or 74AHC2G125DC-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (-40 °C to +125 °C), CMOS input compatibility, 3-state bus-driving capability, and VSSOP8 package footprint for space-constrained ECUs.
Technical Context
This device implements two independent non-inverting buffers, each with a dedicated active-low 3-state output enable. Its logic function follows standard truth table behavior: when nOE = LOW, nY mirrors nA; when nOE = HIGH, nY enters high-impedance state. Input thresholds are CMOS-compatible (VIH = 3.85 V min at VCC = 5.5 V), enabling direct interfacing with 3.3 V and 5 V logic domains.
Dynamic performance is characterized across temperature and supply voltage: propagation delay is 3.4–7.5 ns (VCC = 4.5–5.5 V, CL = 15–50 pF), enable/disable times match propagation delays within ±0.5 ns, and power dissipation capacitance is 9 pF per buffer - enabling accurate dynamic power estimation via PD = CPD × VCC² × fi.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - supports single-rail operation across 3.3 V and 5 V systems without level shifters. |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use. |
| Propagation Delay | 3.4 ns (typ.) at VCC = 5.0 V, CL = 15 pF - enables timing-critical signal buffering in CAN/LIN interface paths. |
| Output Drive Strength | ±8 mA at VCC = 4.5 V - sufficient to drive 15 pF loads with <10 ns edge rates in ECU backplane traces. |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - allows safe interfacing with higher-voltage sensors or legacy 5 V peripherals. |
| Power Dissipation Capacitance | 9 pF per buffer - used to calculate dynamic power consumption in high-frequency data routing applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive board-level ESD robustness requirements per ISO 10605. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located on lower left corner below marking code 'A25'.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 | 1OE, 2OE | Active-low output enable inputs - independently disable each buffer's output to prevent bus contention. |
| 2, 5 | 1A, 2A | Data inputs - accept CMOS-level signals; overvoltage tolerant up to 5.5 V. |
| 3, 6 | 1Y, 2Y | Buffered non-inverting outputs - enter high-impedance state when respective OE is HIGH. |
| 4 | GND | Ground reference (0 V) - must be low-impedance connection for noise immunity and stable switching. |
| 8 | VCC | Supply voltage input - decoupling capacitor (100 nF) required within 5 mm for clean power delivery. |
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 up to 5.5 V input signals even when VCC = 2.0 V - eliminates need for external level translators in mixed-voltage domains. |
| Symmetrical output impedance | Ensures matched rise/fall times (<10% skew) critical for maintaining signal integrity in differential or clock-distribution paths. |
| Low dynamic power consumption | CPD = 9 pF enables sub-1 mW dynamic power at 10 MHz with 3.3 V supply - reduces thermal load in dense ECU layouts. |
| High noise immunity | CMOS input hysteresis and >40% noise margin at VCC = 5 V - suppresses false triggering from EMI in engine bay environments. |

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 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and packaging. | Better suited for legacy 5 V TTL logic interfaces; not recommended for pure CMOS systems due to higher static current. | Select when interfacing with older 5 V microcontrollers or discrete transistor logic where VIH ≤ 2.0 V is required. |
| SN74LVC2G125DBVR | Lower VCC range (1.65–5.5 V), higher drive (±24 mA), but only qualified to industrial grade (-40 °C to +85 °C). | Lacks AEC-Q100 qualification; unsuitable for under-hood or safety-critical automotive locations. | Use only in cabin-infotainment or non-safety ECU sections where extended temperature range is not mandated. |

FAQ
What is the maximum input voltage the 74AHC2G125DC-Q100 can tolerate?
The device accepts input voltages up to 5.5 V regardless of supply voltage - a key feature enabling safe interfacing with higher-voltage peripherals in mixed-voltage automotive subsystems. This overvoltage tolerance is specified in Table 5 (Limiting Values) and confirmed across all operating conditions in the datasheet.
Does this part support hot insertion or live bus connection?
No - while the 3-state outputs prevent contention, the device lacks explicit hot-swap protection circuitry such as slew-rate limiting or current limiting on outputs. Live connection may cause transient glitches or latch-up if VCC is not established before applying input signals, per Absolute Maximum Ratings in Section 8.
Can both buffers be enabled simultaneously without affecting performance?
Yes - the two buffers operate fully independently; enabling both 1OE and 2OE simultaneously does not degrade propagation delay, drive strength, or power consumption. Static and dynamic characteristics in Tables 7–8 are measured with both channels active and confirm no interaction between channels.
Is the VSSOP8 (SOT765-1) package compatible with standard TSSOP8 PCB footprints?
No - the VSSOP8 package has a 2.3 mm body width versus 3.0 mm for TSSOP8 (SOT505-2); pad layout, lead pitch (0.5 mm same), and thermal pad presence differ. Using a TSSOP8 footprint will result in solder bridging or insufficient solder joint area. The correct land pattern is defined in Figure 8 of the datasheet.
