Product details
Overview
74AHC1G125GM,115 from Nexperia is a single CMOS bus buffer/line driver with 3-state output, overvoltage-tolerant inputs (up to 5.5 V), wide supply range (2.0–5.5 V), propagation delay as low as 3.4 ns at 5 V/15 pF, and operation from −40 °C to +125 °C. It serves as a level-translating unidirectional buffer in mixed-voltage I/O interfaces on compact PCBs.
For engineers reviewing the 74AHC1G125GM,115 datasheet, 74AHC1G125GM,115 pinout, 74AHC1G125GM,115 application, or 74AHC1G125GM,115 equivalent, this device is selected for low-power, space-constrained digital signal routing where input voltage translation, fast enable/disable timing, and thermal robustness in industrial environments are critical.
Technical Context
This device implements a single non-inverting buffer with active-low 3-state output control (OE). Its CMOS input structure accepts logic levels compatible with both 3.3 V and 5 V systems, while overvoltage tolerance enables safe interfacing with higher-voltage buses without external clamping.
The XSON6 (SOT886) package features six terminals - including two power pins (VCC, GND), one data input (A), one data output (Y), one output-enable (OE), and one no-connect (n.c.) - enabling high-density placement and efficient thermal dissipation in thermally demanding applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.0 V to 5.5 V - supports direct integration into 3.3 V and 5 V logic domains without level shifters. |
| Input voltage tolerance | Up to 5.5 V - allows use as bidirectional voltage translator between 1.8 V/3.3 V controllers and 5 V peripherals. |
| Propagation delay (A→Y) | 3.4 ns (typ) at VCC = 5.0 V, CL = 15 pF - ensures sub-5 ns signal path timing for high-speed control lines. |
| Enable/disable time (OE→Y) | 3.6 ns (typ enable), 4.1 ns (typ disable) at VCC = 5.0 V, CL = 15 pF - minimizes bus contention during state transitions. |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood, industrial PLC, and motor drive control environments. |
| Output drive strength | ±8 mA at VCC = 4.5 V - sufficient to drive 15 pF loads across standard PCB traces without added buffering. |
| Power dissipation capacitance | 9 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi) in battery-sensitive designs. |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886); no leads; 6 terminals; body dimensions 1.0 mm × 1.45 mm × 0.5 mm; thermal pad not present; side-wettable flanks not included.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A (data input) | CMOS-compatible unidirectional input accepting 0–5.5 V; tolerant of overvoltage during hot-swap or mixed-rail operation. |
| 2 | OE (output enable) | Active-low 3-state control; pulls Y to high-impedance when HIGH; synchronizes bus release with system control signals. |
| 3 | GND | Reference ground for all internal circuitry and I/O; must be connected to system ground plane for noise immunity and ESD discharge path. |
| 4 | n.c. | No internal connection; left floating per design; no external tie required; improves layout flexibility in dense routing. |
| 5 | VCC | Primary supply rail; decoupling capacitor (100 nF ceramic) recommended within 3 mm for stable switching performance. |
| 6 | Y (data output) | Buffered, non-inverting output with symmetrical rise/fall times; drives capacitive loads up to 50 pF with <9.5 ns max delay. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Withstands 5.5 V regardless of VCC (2.0–5.5 V), eliminating need for external clamping diodes in mixed-voltage interconnects. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times (<10% skew), reducing signal integrity risk on shared buses. |
| Low dynamic power | CPD = 9 pF enables <10 μW/MHz dynamic power at 3.3 V - critical for always-on sensor interface and low-duty-cycle control nodes. |
| High noise immunity | Typical VIH/VIL margins >0.7 V at 3.3 V supply - rejects board-level coupling noise in electrically noisy industrial enclosures. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overvoltage events in motor drive gate drivers. |
Applications
| Industrial Sensor Interface | PLC I/O Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G125GM,115 | TTL-compatible input thresholds (VIH = 2.0 V min at 4.5–5.5 V); identical pinout, package, and timing. | Better suited for legacy 5 V TTL systems where input noise margin must match older logic families. | Select when interfacing with 74LS or 74F series outputs; avoid if driving from modern low-VOL CMOS sources. |
| SN74LVC1G125DBVR | Lower VCC range (1.65–5.5 V); higher drive (±32 mA); different pinout (SOT-23-5); no overvoltage tolerance. | Preferred for ultra-low-voltage (1.8 V) microcontrollers but requires external protection for 5 V bus exposure. | Choose for 1.8 V core logic domains; reject if overvoltage resilience or pin compatibility with existing XSON6 layouts is required. |
Compared with 74AHCT1G125GM,115, the AHC variant offers superior noise immunity in mixed-signal environments; versus SN74LVC1G125DBVR, it trades higher drive strength for guaranteed 5.5 V input tolerance and drop-in XSON6 compatibility in space-constrained industrial designs.

FAQ
What is the maximum input voltage the 74AHC1G125GM,115 can tolerate when VCC = 3.3 V?
The device supports input voltages up to 5.5 V regardless of VCC level, as confirmed in Section 2 (Features and benefits) and Table 5 (Limiting values). This overvoltage tolerance enables safe interfacing with 5 V buses while powered from 3.3 V, eliminating external protection components in mixed-rail designs.
Does the n.c. pin on the SOT886 package require grounding or leaving floating?
Pin 4 is explicitly designated "n.c." (not connected) in Table 3 (Pin description) and carries no internal bond wire or circuit connection. It must remain unconnected - neither grounded nor tied to any voltage - to avoid unintended parasitic coupling or mechanical stress on the die attach.
Can the 74AHC1G125GM,115 drive a 50 pF load within its specified propagation delay?
Yes: Table 8 (Dynamic characteristics) specifies tpd ≤ 11.5 ns (max) at VCC = 3.0–3.6 V and CL = 50 pF, and ≤ 9.5 ns (max) at VCC = 4.5–5.5 V and CL = 50 pF. These values include test conditions matching real-world PCB trace and receiver input capacitance.
Is the XSON6 package (SOT886) lead-free and RoHS compliant?
Yes: Nexperia confirms RoHS compliance and lead-free construction for all 74AHC1G125 variants, including SOT886, per their public product compliance documentation and the "Legal information" section of the datasheet (Rev. 15.1, page 14), which references adherence to EU Directive 2011/65/EU.
