Product details
Overview
74AHC1G125GW,165 from Nexperia is a single CMOS bus buffer/line driver with 3-state output, designed for voltage-level translation in mixed-voltage systems. It operates from 2.0 V to 5.5 V, features overvoltage-tolerant inputs up to 5.5 V, and delivers symmetrical output impedance with balanced propagation delays (typ. 3.4 ns at 5 V, 15 pF). It is used in low-power I/O expansion and bidirectional bus isolation in industrial microcontroller interfaces.
For engineers reviewing the 74AHC1G125GW,165 datasheet, 74AHC1G125GW,165 pinout, 74AHC1G125GW,165 application, or 74AHC1G125GW,165 equivalent, this device serves as a compact, temperature-stable (–40 °C to +125 °C), low-noise buffer for signal integrity-critical digital interconnects where input tolerance and 3-state control are essential.
Technical Context
This device implements a 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 CMOS input threshold scales with VCC (VIH = 3.85 V min at VCC = 5.5 V), enabling reliable interfacing across 3.3 V and 5 V domains without level shifters.
It supports fast switching with tpd ≤ 7.0 ns (VCC = 5 V, CL = 15 pF), ten ≤ 6.5 ns, and tdis ≤ 8.5 ns under same conditions. Input capacitance is 10 pF max, and ICC remains ≤ 40 μA at VCC = 5.5 V across full temperature range, confirming suitability for battery-sensitive and thermally constrained embedded nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 5.5 V - Enables direct operation from 3.3 V or 5 V rails without regulators. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection of 5 V signals to 3.3 V system buses without external clamping. |
| Propagation Delay | 3.4 ns (typ) at VCC = 5.0 V, CL = 15 pF - Supports >100 MHz data rates in short trace applications. |
| Output Drive | ±8 mA at VCC = 4.5 V - Sufficient to drive 15 pF loads with <0.55 V VOL and >3.7 V VOH at 125 °C. |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood, industrial control, and extended ambient environments. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Reduces need for external ESD protection in board-level I/O design. |
| Power Dissipation | 250 mW max (TSSOP5) - Enables use in space-constrained PCB layouts without forced cooling. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm pitch, 1.3 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable (active-low) | Asserting LOW enables buffer output; HIGH forces Y into high-Z - critical for bus arbitration and shared-line contention control. |
| 2 (A) | Data input | CMOS-compatible input with VIH/VIL scaling to VCC - accepts TTL or CMOS logic levels depending on supply. |
| 3 (GND) | Ground reference | 0 V return path for all internal logic and output current - must be low-impedance to maintain noise immunity. |
| 4 (Y) | Buffered output | Non-inverting, 3-state output with symmetrical rise/fall times - matches load impedance for minimal signal distortion. |
| 5 (VCC) | Supply voltage | Primary power rail (2.0–5.5 V); powers internal logic and output stage - decoupling capacitor required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V to 5.5 V - Eliminates need for separate voltage translators in multi-rail systems like MCU + sensor node designs. |
| Overvoltage-tolerant inputs | 5.5 V absolute max on A/OE pins - permits direct connection to 5 V peripherals while powered from 3.3 V, reducing BOM count. |
| High noise immunity | Typical 40 % VCC noise margin - ensures robust operation in electrically noisy industrial enclosures with motor drives or relays. |
| Low dynamic power | CPD = 9 pF - limits switching power to <1 μW at 1 MHz, supporting always-on low-power monitoring functions. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overvoltage events. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G125GW,165 | TTL-compatible input thresholds (VIH = 2.0 V min at VCC = 4.5 V), otherwise identical pinout and specs. | Better suited for legacy 5 V TTL logic interfacing; less tolerant of sub-2 V noise on input lines. | Select when interfacing with older 5 V TTL peripherals where CMOS input thresholds cause marginal recognition. |
| SN74LVC1G125DBVR | Lower VCC range (1.65–5.5 V), higher drive (±32 mA), but no overvoltage tolerance - max VI = VCC + 0.5 V. | Requires external clamping for 5 V inputs; preferred in high-speed, low-VCC (1.8 V) FPGA I/O banks. | Choose only if operating below 2.0 V or requiring >±8 mA drive; avoid in mixed-voltage translation roles. |
Compared with 74AHCT1G125GW,165, the AHC variant offers superior noise margin in CMOS systems; versus SN74LVC1G125DBVR, it trades raw drive strength for robust 5.5 V input tolerance - making it optimal for voltage-domain bridging without added protection components.

FAQ
What is the maximum input voltage the 74AHC1G125GW,165 can tolerate on its A and OE pins?
The device supports absolute maximum input voltage of 5.5 V on A and OE pins regardless of VCC level - a key feature enabling safe interfacing with 5 V signals while powered from 3.3 V or lower supplies. This overvoltage tolerance is verified per datasheet Table 5 and eliminates need for external clamping diodes in mixed-voltage designs.
Can the 74AHC1G125GW,165 operate reliably at 2.0 V supply and –40 °C ambient?
Yes - the datasheet specifies guaranteed operation from 2.0 V to 5.5 V and –40 °C to +125 °C. At VCC = 2.0 V and –40 °C, VIH remains ≥1.5 V and VOL ≤0.5 V at 4 mA load, ensuring functional compatibility with 1.8 V logic families and cold-environment deployments such as outdoor utility meters.
How does the 3-state enable function behave during power-up or brownout conditions?
OE is active-low and internally pulled down via weak keeper circuitry; during VCC ramp-up, the output remains in high-impedance state until VCC exceeds ~1.0 V, preventing bus glitches. No external pull-up is required on OE - the default HIGH state ensures safe power sequencing in multi-rail systems.
Is the 74AHC1G125GW,165 pin-compatible with other packages in the same family?
No - the GW suffix denotes TSSOP5 (SOT353-1), which has 5 pins in 0.65 mm pitch. The GV (SC-74A/SOT753), GM (XSON6/SOT886), and GZ (XSON5/SOT8065-1) variants differ in pin count (5 vs 6), terminal layout, and footprint - requiring separate PCB land patterns. Only same-suffix variants (e.g., 74AHC1G125GW,125) are drop-in replacements.
