Product details
Overview
74AHC2G125DP,125 from Nexperia is a dual CMOS buffer/line driver with 3-state outputs, designed for bidirectional bus interfacing and level translation in mixed-voltage systems (2.0 V to 5.5 V). It features overvoltage-tolerant inputs up to 5.5 V, symmetrical output impedance, and operates across -40 °C to +125 °C - enabling use in industrial control backplanes and sensor interface modules.
For engineers reviewing the 74AHC2G125DP,125 datasheet, 74AHC2G125DP,125 pinout, 74AHC2G125DP,125 application, or 74AHC2G125DP,125 equivalent, key selection criteria include 3-state timing (tpd ≤ 5.5 ns at 5 V/15 pF), input voltage compatibility (CMOS-level), thermal robustness, and TSSOP8 package suitability for high-density PCB layouts.
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state enable (1OE, 2OE) controlling output impedance. The logic function follows standard truth table behavior: when nOE = L, nY = nA; when nOE = H, nY = Z (high-impedance).
It supports mixed-voltage translation via overvoltage-tolerant inputs (VI up to 5.5 V regardless of VCC), while maintaining CMOS input thresholds (VIH ≥ 3.85 V at VCC = 5.5 V). Propagation delay and enable/disable times are characterized across full temperature and voltage ranges, with CPD = 9 pF per buffer for dynamic power estimation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - enables direct interface with 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Propagation Delay (tpd) | ≤ 5.5 ns at VCC = 5.0 V, CL = 15 pF - ensures sub-6 ns signal path timing for high-speed digital buses. |
| Enable Time (ten) | ≤ 6.5 ns at VCC = 5.0 V, CL = 15 pF - guarantees fast bus arbitration and low-latency tri-state control. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - allows safe connection to higher-voltage peripherals in mixed-supply systems. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and outdoor edge nodes. |
| Output Drive Strength | ±8 mA at VCC = 4.5 V - sufficient to drive 15–50 pF loads typical in point-to-point or short-bus configurations. |
| Power Dissipation Capacitance | CPD = 9 pF per buffer - enables accurate dynamic power calculation (PD = CPD × VCC² × fi) for thermal design. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 index located on lower left corner below marking code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 (1OE, 2OE) | Active-low output enable | Drives respective output (1Y or 2Y) into high-impedance state when HIGH; enables pass-through when LOW. |
| 2, 5 (1A, 2A) | Data input | CMOS-compatible input accepting voltages up to 5.5 V regardless of VCC; no external pull-up required. |
| 3, 6 (2Y, 1Y) | Data output | Non-inverting buffered output with symmetrical rise/fall times and ±8 mA drive capability. |
| 4 | GND | Reference ground (0 V) for all input/output voltage levels and internal circuitry. |
| 8 | VCC | Primary supply rail (2.0–5.5 V); powers both buffers and enable logic; decoupling capacitor recommended. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Ensures matched rise/fall times (<10% skew) for clean signal integrity on bidirectional data lines. |
| Balanced propagation delays | tpd variation ≤ 1.5 ns between channels supports synchronous multi-signal routing in timing-critical paths. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V inputs at any VCC (2.0–5.5 V), eliminating need for external clamping diodes in mixed-voltage interconnects. |
| High noise immunity | VIH/VIL margins > 1.2 V at VCC = 3.3 V and > 2.0 V at VCC = 5.0 V reduce susceptibility to EMI-induced glitches. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overvoltage events. |
Applications
| Industrial Sensor Interface | Embedded Microcontroller Bus Expansion |
|---|---|
|
Use Scenario: Connecting analog sensor ADCs with 5 V output swing to a 3.3 V microcontroller I/O port. IC Role / Device Role / Timing Role: Level-translating buffer isolating voltage domains while preserving signal timing integrity. Use Value: Eliminates external level shifters; overvoltage-tolerant inputs accept 5 V signals directly at 3.3 V VCC, reducing BOM count and board area. |
Use Scenario: Expanding GPIO count on an ARM Cortex-M4 MCU by adding isolated peripheral control lines. IC Role / Device Role / Timing Role: Dual 3-state buffer enabling time-multiplexed access to shared address/data lines. Use Value: Enables bus sharing between multiple peripherals using OE-controlled isolation; <6 ns tpd maintains system timing budget. |
| Automotive Body Control Module | Test Equipment Signal Conditioning |
|
Use Scenario: Driving LED status indicators and relay drivers from a 3.3 V CAN node MCU in under-dash environments. IC Role / Device Role / Timing Role: Robust buffer providing current gain and ESD-hardened I/O for noisy 12 V vehicle electrical systems. Use Value: -40 °C to +125 °C rating and HBM >2000 V ensure reliable operation in thermally stressed automotive enclosures. |
Use Scenario: Isolating DUT signals from automated test equipment during functional validation of digital subsystems. IC Role / Device Role / Timing Role: Bidirectional line driver buffering test vectors and capturing responses without loading source circuits. Use Value: High-impedance OFF-state (IOZ < 0.25 μA) prevents signal corruption during test mode transitions. |
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 |
|---|---|---|---|
| 74AHCT2G125DP,125 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and packaging. | Better suited for legacy 5 V TTL systems where input thresholds must match older logic families. | Select when interfacing with 5 V TTL sources; avoid if only CMOS-level inputs are present. |
| SN74LVC2G125DPWR | Lower VCC range (1.65–5.5 V), slightly faster tpd (4.2 ns @ 3.3 V), same TSSOP8 footprint. | Enables 1.8 V domain interfacing and offers marginally better speed at lower supply voltages. | Select for 1.8 V–3.3 V systems requiring tighter timing budgets; verify VIH/VIL compatibility. |
Compared with 74AHCT2G125DP,125, the AHC variant provides stricter CMOS input thresholds for noise resilience in mixed-signal environments; compared with SN74LVC2G125DPWR, it trades marginal speed for broader 2.0 V minimum VCC compliance and enhanced latch-up immunity.

FAQ
What is the maximum input voltage the 74AHC2G125DP,125 can tolerate?
The device accepts input voltages up to 5.5 V regardless of VCC setting - a feature explicitly enabled by its overvoltage-tolerant input structure. This allows safe interfacing with 5 V peripherals even when powered from 2.5 V or 3.3 V supplies, without external protection components.
Can the 74AHC2G125DP,125 drive a 50 pF load at 5 MHz while staying within power limits?
Yes: at VCC = 5.0 V and fi = 5 MHz, dynamic power per buffer is PD ≈ CPD × VCC² × fi = 9 pF × 25 V² × 5 MHz = 1.125 mW. Total for both buffers is ~2.25 mW - well below the 250 mW Ptot limit for the TSSOP8 package at +25 °C.
How does the 3-state disable behavior affect bus contention risk?
When either 1OE or 2OE is HIGH, the corresponding output enters high-impedance (Z) state with IOZ ≤ 0.25 μA at VCC = 5.5 V. This effectively removes the output from the bus, preventing contention with other drivers - critical for shared data/address lines in multiplexed architectures.
Is the 74AHC2G125DP,125 qualified for automotive applications?
No - although rated for -40 °C to +125 °C, this part is not AEC-Q100 qualified and lacks automotive-specific stress testing, failure analysis, or PPAP documentation. It may be used in non-safety-critical automotive subsystems at the designer's own risk, but is not approved for ASIL-B or higher functions.
