Product details
Overview
74AHC1G126GM,132 from Nexperia is a single CMOS bus buffer/line driver with 3-state output and overvoltage-tolerant inputs (up to 5.5 V), enabling voltage-level translation in mixed-supply systems. It operates from 2.0 V to 5.5 V, supports -40 °C to +125 °C ambient range, and delivers propagation delay as low as 3.4 ns (VCC = 5.0 V, CL = 15 pF). Used in industrial I/O expansion and low-power microcontroller peripheral interfacing.
For engineers reviewing the 74AHC1G126GM,132 datasheet, 74AHC1G126GM,132 pinout, 74AHC1G126GM,132 application, or 74AHC1G126GM,132 equivalent, key selection criteria include 3-state control timing (enable/disable < 9.5 ns), input overvoltage tolerance for level-shifting, symmetrical output drive (±8 mA), wide supply range compatibility, and XSON6 package suitability for space-constrained PCB layouts.
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 structure accepts TTL-compatible thresholds only in the AHCT variant - this part (74AHC1G126) uses pure CMOS input levels (VIH ≥ 3.85 V at VCC = 5.5 V).
Designed for signal integrity in dense digital interfaces, it features balanced tPLH/tPHL propagation delays (< 0.5 ns skew), symmetrical output impedance, and low dynamic power dissipation (CPD = 9 pF). Input clamping diodes and ESD protection (HBM > 2000 V, CDM > 1000 V) support robust operation in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - enables direct interface with 3.3 V and 5 V logic domains without level shifters. |
| Input Overvoltage Tolerance | Up to 5.5 V - allows safe connection of 5 V signals to 3.3 V or 2.5 V powered systems. |
| Propagation Delay (A→Y) | 3.4 ns typical (VCC = 5.0 V, CL = 15 pF) - supports >100 MHz data rates in short trace applications. |
| Output Drive Strength | ±8 mA (VOH/VOL @ VCC = 4.5 V) - sufficient to drive 15 pF loads with < 0.55 V VOL and > 3.7 V VOH across temperature. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor controllers. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - exceeds JEDEC JS-001/JS-002 Class 2/C3 for board-level handling robustness. |
| 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), 1.0 mm × 1.45 mm × 0.5 mm body, no leads, 6 terminals, side-wettable flanks not present (distinct from GZ variant), rated for reflow per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data input | Non-inverting input signal path; CMOS-compatible threshold; tolerant to 5.5 V regardless of VCC. |
| OE | Output enable (active LOW) | Asynchronous 3-state control; drives Y to high-Z when HIGH; no internal pull-up/pull-down. |
| GND | Ground reference | Primary return path for all I/O and supply currents; must be low-inductance connection. |
| n.c. | No connect | Terminal 5 is unconnected internally; must remain floating or grounded per layout best practice - not used for thermal relief. |
| VCC | Positive supply | Single supply rail powering both input and output stages; bypassing with 100 nF ceramic near pin required. |
| Y | 3-state buffered output | Inverting logic not applied - Y = A when OE = LOW; high-Z when OE = HIGH; capable of sourcing/sinking ±8 mA. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Enables matched rise/fall times (tPLH ≈ tPHL), reducing signal distortion on bidirectional buses. |
| Balanced propagation delays | Max skew < 0.5 ns between rising/falling edges ensures clean timing margins in synchronous interfaces. |
| Wide supply voltage range | 2.0–5.5 V operation eliminates need for external regulators when interfacing legacy 5 V and modern 3.3 V subsystems. |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs while powered from 2.0 V - enables true level translation without external components. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overvoltage events. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

IC Role / Device Role / Timing Role: Low-power bus repeater extending trace length while maintaining signal integrity at 400 kHz I²C speeds. Use Value: 2.0 V minimum VCC supports energy harvesting power rails; XSON6 footprint saves >60% board area vs. TSSOP5 alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G126GM,132 | TTL-input thresholds (VIH = 2.0 V min), identical output specs and package. | Required where driving from legacy 5 V TTL logic; incompatible with pure CMOS 2.5 V sources. | Select only if interfacing 5 V TTL outputs; otherwise 74AHC1G126GM offers broader voltage compatibility. |
| SN74LVC1G126DBVR | Lower VCC range (1.65–5.5 V), higher drive (±32 mA), different pinout (SOT-23-5), no overvoltage tolerance. | Suitable for ultra-low-voltage SoC I/O expansion but requires external clamping for 5 V signal ingress. | Choose when 1.8 V operation or stronger drive is mandatory; avoid where 5 V signal translation is needed. |
Compared with 74AHCT1G126GM,132, this AHC variant provides superior mixed-voltage flexibility; versus SN74LVC1G126DBVR, it trades higher drive strength for essential overvoltage safety in heterogeneous signal environments.

FAQ
What is the maximum clock/data rate supported by 74AHC1G126GM,132?
The device does not specify a maximum clock frequency, but its propagation delay (3.4 ns typical at 5 V, 15 pF) and enable/disable times (< 9.5 ns) support reliable operation with data edges up to ~100 MHz in point-to-point configurations. System-level timing depends on trace capacitance, termination, and load - actual usable rate must be validated per layout using worst-case tpd and skew values from Table 8.
Can 74AHC1G126GM,132 be used as a level shifter between 1.8 V and 5 V domains?
No - while inputs tolerate up to 5.5 V regardless of VCC, the output high voltage (VOH) is bounded by VCC. When powered from 1.8 V, VOH cannot exceed ~1.6 V (per static characteristics), making it unsuitable for driving 5 V logic. It functions as a *downward* translator (5 V in → 3.3/2.5 V out) only when VCC matches the target domain.
Is the n.c. pin (pin 5) in the XSON6 package required to be left floating?
Yes - pin 5 is internally unconnected and must remain electrically floating. Do not tie to GND or VCC. While grounding may appear benign in simulation, it risks unintended current paths during ESD events or violates Nexperia's recommended layout per SOT886 mechanical drawing; floating ensures compliance with qualification testing conditions.
Does 74AHC1G126GM,132 support hot-swap or live-insertion?
No - the device lacks built-in hot-swap protection circuitry such as slew-rate limiting or back-drive prevention. Applying VCC while signals are present may cause bus contention or violate absolute maximum ratings (e.g., VI > VCC + 0.5 V). For hot-swap applications, add external series resistors and ensure power sequencing per system-level requirements.
