Product details
Overview
74AHC1G125GF,132 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 digital interfaces such as I²C pull-up domains, microcontroller GPIO expansion, and FPGA I/O conditioning.
For engineers reviewing the 74AHC1G125GF,132 datasheet, 74AHC1G125GF,132 pinout, 74AHC1G125GF,132 application, or 74AHC1G125GF,132 equivalent, this device is selected for low-power, high-noise-immunity signal buffering where input overvoltage tolerance and precise 3-state control are required in space-constrained industrial and automotive-qualified systems.
Technical Context
This IC implements a single non-inverting buffer with active-low 3-state enable (OE), supporting bidirectional voltage translation via overvoltage-tolerant inputs that accept up to 5.5 V regardless of VCC (2.0–5.5 V). Its symmetrical output impedance ensures matched rise/fall times and balanced propagation delays (tpd ≤ 5.5 ns, tdis ≤ 9.5 ns at 5 V/50 pF).
The logic function follows standard IEEE/IEC truth table: when OE = LOW, Y = A; when OE = HIGH, Y = high-impedance. Input thresholds are CMOS-compatible (VIH ≥ 3.85 V @ VCC = 5.5 V), and static drive strength is ±8 mA at VOH/VOL specifications, enabling direct interfacing with legacy TTL and modern low-voltage logic.
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 systems without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - enables safe interfacing with higher-voltage buses while powered from lower VCC. |
| Propagation Delay | 3.4 ns (typ) at VCC = 5.0 V, CL = 15 pF - ensures timing-critical signal integrity in high-speed digital control paths. |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive 15–50 pF loads across PCB traces and multiple gate inputs. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and extended-range embedded applications. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - robust handling during automated assembly and field service. |
| Power Dissipation | CPD = 9 pF - enables accurate dynamic power estimation (PD = CPD × VCC² × fi) for battery-sensitive designs. |
Pinout & Package
XSON5 plastic thermal-enhanced extremely thin small outline package (SOT8065-1); 5-terminal, no leads; body dimensions 1.1 × 0.85 × 0.5 mm; side-wettable flanks for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | 0 V return path for all internal circuitry and output current sinking. |
| VCC | Positive supply | Primary power rail (2.0–5.5 V); powers internal logic and output stage. |
| Y | Data output | Buffered, 3-state output; driven HIGH/LOW when OE = LOW, high-Z when OE = HIGH. |
| OE | Output enable (active-low) | Asynchronous control input; asserts 3-state mode when HIGH, enables pass-through when LOW. |
| A | Data input | CMOS-level input accepting 0–5.5 V; tolerant of voltages exceeding VCC for mixed-rail translation. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Accepts up to 5.5 V independent of VCC - eliminates external clamping diodes in multi-supply systems. |
| Symmetrical output impedance | Matched rise/fall characteristics ensure minimal signal distortion and reduced EMI in high-frequency switching. |
| Low dynamic power | CPD = 9 pF enables sub-μW dynamic consumption at 1 MHz - critical for always-on sensor interface nodes. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overvoltage events. |
| Thermal-enhanced XSON5 | SOT8065-1 package with side-wettable flanks improves solder joint reliability and thermal dissipation in dense layouts. |
Applications

IC Role / Device Role / Timing Role: Single-buffer fanout device with precise 3-state control synchronized to FPGA clock domain. Use Value: Propagation delay variation < 1 ns (tpd min/max spread) ensures deterministic timing margin for multi-slave SPI chip-select assertion. |
Use Scenario: Interfacing modern 3.3 V microcontrollers with legacy 5 V parallel EEPROMs in industrial HMIs. IC Role / Device Role / Timing Role: CMOS-input buffer translating MCU address/data bits to 5 V EEPROM bus while maintaining noise immunity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHC1G125GW,115 | TSSOP5 package (5-lead, 1.25 mm body width); 0.65 mm lead pitch; no side-wettable flanks. | Less suitable for automated AOI and reflow process control in high-reliability automotive production. | Select when board-level test access or hand-soldering is prioritized over thermal performance and IPC-A-610 compliance. |
| 74AHCT1G125GV,125 | TTL-compatible input thresholds (VIH = 2.0 V @ VCC = 4.5 V); identical XSON5 package and pinout. | Better suited for interfacing with legacy 5 V TTL outputs but lacks overvoltage tolerance beyond VCC. | Choose only when driving from strict 5 V TTL sources and overvoltage translation is not required. |

FAQ
What is the maximum input voltage the 74AHC1G125GF,132 can tolerate when VCC = 3.3 V?
The device supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level. When powered at 3.3 V, the A input safely accepts 5 V signals without damage or clamping, enabling direct connection to 5 V buses in mixed-voltage systems without external protection components.
Does the 74AHC1G125GF,132 support hot insertion or live bus connection?
Yes - its overvoltage-tolerant inputs and high-impedance OFF-state (IOZ ≤ 10 μA) allow safe connection to powered buses. The 3-state output remains isolated until OE is asserted, preventing contention during plug-in or system bring-up sequences in modular backplane or docking applications.
How does the XSON5 (SOT8065-1) package improve thermal performance over TSSOP5?
The SOT8065-1 package features side-wettable flanks and a thermally enhanced die pad structure, achieving lower junction-to-board thermal resistance (RθJB ≈ 120 K/W vs. ~180 K/W for TSSOP5), which sustains full ±8 mA drive capability at +125 °C ambient without derating in compact PCB layouts.
Can the 74AHC1G125GF,132 be used as a level shifter between 1.8 V and 5 V domains?
No - it is not a bidirectional level shifter. While the input tolerates 5 V with VCC = 1.8 V, the output swing is limited to VCC (1.8 V), making it unsuitable for driving 5 V logic. It functions only as a unidirectional buffer with overvoltage-tolerant input, not as a true voltage translator with dual-rail output capability.
