Product details
Overview
74AHCT1G125GM,115 from Nexperia is a single 3-state bus buffer/line driver with TTL-compatible inputs, 2.0–5.5 V supply range, overvoltage-tolerant inputs (up to 5.5 V), and operation across –40 °C to +125 °C. It functions as a level-translating output-enable-controlled signal pass-through in mixed-voltage digital interfaces such as microcontroller GPIO expansion and legacy peripheral interfacing.
For engineers reviewing the 74AHCT1G125GM,115 datasheet, 74AHCT1G125GM,115 pinout, 74AHCT1G125GM,115 application, or 74AHCT1G125GM,115 equivalent, this device is selected for low-power, high-noise-immunity unidirectional buffering where input voltage translation and precise 3-state control are required in space-constrained industrial and embedded systems.
Technical Context
The 74AHCT1G125GM,115 implements a single-channel non-inverting buffer with active-low 3-state enable logic: when OE is LOW, Y follows A; when OE is HIGH, Y enters high-impedance state. 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 5 V TTL logic families while operating from 4.5–5.5 V supplies.
It features symmetrical output drive (±8 mA at VCC = 4.5 V), balanced propagation delays (tpd = 3.4–5.5 ns typical at CL = 15 pF, VCC = 5.0 V), and overvoltage-tolerant inputs that accept up to 5.5 V regardless of VCC - enabling safe interfacing between 3.3 V controllers and 5 V peripherals without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - supports stable operation in standard 5 V digital systems with margin for rail variation. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures reliable recognition of TTL logic levels at 5 V supply. |
| Output Drive | ±8 mA - sufficient to drive 15 pF loads with <7 ns propagation delay and maintain signal integrity on short PCB traces. |
| Propagation Delay | 3.4 ns (typ, CL = 15 pF, VCC = 5.0 V) - enables use in sub-100 MHz digital control paths with timing margin. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood, industrial PLC, and high-reliability embedded applications. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - robust handling during automated assembly and field service. |
| Power Dissipation | ICC ≤ 40 μA (max, VCC = 5.5 V) - ultra-low static current suitable for always-on monitoring circuits. |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886), 1.0 × 1.45 × 0.5 mm body, no leads, 6 terminals, thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | Data input - accepts TTL-level signals; overvoltage tolerant up to 5.5 V independent of VCC. |
| 2 | OE | Active-low output enable - drives Y into high-Z when HIGH; must be pulled LOW to enable buffer function. |
| 3 | GND | Ground reference - return path for all internal currents; requires low-impedance PCB connection. |
| 4 | n.c. | No connection - terminal is internally unconnected and must remain floating; no PCB trace or soldering. |
| 5 | VCC | Positive supply - powers internal CMOS circuitry; bypass capacitor (100 nF) recommended near pin. |
| 6 | Y | 3-state buffered output - delivers inverted-pass-through signal (Y = A when OE = LOW); high-Z when OE = HIGH. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V, VIL ≤ 0.8 V at 5 V supply - interoperates directly with legacy 74LS, 74F, and microcontroller GPIOs without level-shifting. |
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC - enables safe interface between 3.3 V SoCs and 5 V peripherals (e.g., displays, sensors). |
| Symmetrical output impedance | Matched pull-up/pull-down strength (±8 mA) - minimizes rise/fall time skew and reduces signal distortion on shared buses. |
| High noise immunity | Typical noise margin > 0.7 V at VCC = 5 V - suppresses false triggering from EMI or crosstalk in noisy industrial environments. |
| Low dynamic power | CPD = 11 pF - limits switching power (PD = CPD × VCC² × fi) in high-frequency enable/disable cycling applications. |
Applications
| Industrial Sensor Interface | Microcontroller GPIO Expansion |
|---|---|
Use Scenario: Isolating and buffering analog-to-digital converter (ADC) status lines and control signals in programmable logic controller (PLC) backplanes. IC Role / Device Role / Timing Role: Unidirectional 3-state buffer enabling multiplexed access to multiple ADCs via shared data bus; OE synchronized to controller address decode. Use Value: Prevents bus contention during ADC conversion cycles and extends effective trace length by driving 50 pF loads with <9.5 ns disable time. |
Use Scenario: Expanding limited GPIO count of ARM Cortex-M0+ MCU to drive multiple LED indicators and pushbutton inputs in medical handheld devices. IC Role / Device Role / Timing Role: Level-translating buffer translating 3.3 V MCU outputs to 5 V LED drivers while supporting hot-plug detection via OE-controlled tri-state. Use Value: Eliminates need for discrete MOSFET translators; overvoltage tolerance protects MCU pins from 5 V feedback transients. |
| Legacy Peripheral Interfacing | Test Equipment Signal Routing |
Use Scenario: Connecting modern FPGA-based test boards to legacy 5 V parallel port peripherals (e.g., GPIB adapters, printer interfaces). IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional buffer used in direction-controlled data lanes; OE tied to FPGA control register. Use Value: Ensures TTL-level compatibility and prevents back-driving damage during hot-swap events due to input overvoltage tolerance. |
Use Scenario: Routing calibrated clock and trigger signals between modular instrumentation modules in automated test equipment (ATE) racks. IC Role / Device Role / Timing Role: Low-skew, enable-gated signal repeater isolating source modules from load-dependent delay variations. Use Value: Propagation delay matching (tpd variation <1.5 ns across temperature) maintains sub-nanosecond timing alignment across channels. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G125GV,115 | SC-74A (SOT753) package, 5-pin, no n.c. terminal; identical electrical specs. | Less compact footprint (2.7 × 1.7 mm vs. 1.45 × 1.0 mm); higher thermal resistance (3.8 mW/K derating above 85 °C). | Select when board reworkability or wave-solder compatibility is prioritized over size and thermal performance. |
| SN74LVC1G125DBVR | CMOS-input variant (not TTL); VIH = 1.7 V min at VCC = 3.3 V; lower VCC range (1.65–5.5 V). | Not pin-compatible (SOT-23-5); requires redesign if TTL-level sourcing or strict 5 V operation is mandatory. | Select only when migrating to 3.3 V–only systems and full TTL compatibility is unnecessary. |
Compared with 74AHCT1G125GV,115, the GM version offers 30 % smaller area and superior thermal derating; versus SN74LVC1G125DBVR, it guarantees TTL input compatibility but lacks sub-3 V operation - making it optimal for 5 V legacy integration where size and robustness are critical.

FAQ
Can 74AHCT1G125GM,115 operate with a 3.3 V supply?
No - the 74AHCT1G125 variant is specified only for 4.5 V to 5.5 V supply. Its TTL input thresholds require minimum 4.5 V VCC to guarantee VIH ≥ 2.0 V and VIL ≤ 0.8 V per datasheet Table 6. For 3.3 V operation, use the 74AHC1G125GM,115 (CMOS-input) variant instead.
What is the function of the n.c. pin (pin 4) in the XSON6 package?
Pin 4 is a no-connect terminal - internally unconnected and electrically isolated. It must remain unconnected on the PCB; no trace, solder, or grounding is permitted. This terminal exists solely for mechanical symmetry and package standardization in the SOT886 outline.
How does overvoltage tolerance protect system-level interfaces?
Inputs tolerate up to 5.5 V regardless of VCC, allowing safe connection to 5 V signals even when powered from 3.3 V (e.g., 74AHC1G125GM) or 5 V (74AHCT1G125GM). This eliminates risk of latch-up or damage during power sequencing mismatches or transient overshoots on shared buses.
Is thermal pad exposure required for the XSON6 package?
No - the XSON6 (SOT886) package has no exposed thermal pad. Heat dissipation occurs through the die attach and terminal conduction paths. PCB layout should prioritize low-thermal-resistance copper pours under pins 3 (GND) and 5 (VCC), not under the center body.
