Product details
Overview
74AHCT1G125GM,132 from Nexperia is a single 3-state bus buffer/line driver with TTL-compatible inputs and overvoltage-tolerant inputs up to 5.5 V, operating from 4.5 V to 5.5 V supply, delivering propagation delay as low as 3.4 ns (VCC = 5.0 V, CL = 15 pF), and rated for -40 °C to +125 °C ambient temperature - used in voltage-level translation between 3.3 V and 5 V logic domains on industrial control backplanes.
For engineers reviewing the 74AHCT1G125GM,132 datasheet, 74AHCT1G125GM,132 pinout, 74AHCT1G125GM,132 application, or 74AHCT1G125GM,132 equivalent, key selection criteria include TTL input threshold compatibility, 3-state output drive capability (±8 mA), XSON6 package thermal performance, and guaranteed operation across extended industrial temperature range.
Technical Context
This device implements a non-inverting buffer with active-low 3-state enable control (OE), where output Y follows input A when OE is LOW and enters high-impedance state when OE is HIGH. Its TTL-level input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V) ensure direct compatibility with legacy 5 V TTL outputs without level-shifting circuitry.
The XSON6 (SOT886) package features six terminals - including dedicated VCC, GND, A, Y, OE, and n.c. - with no leads and 1.0 × 1.45 × 0.5 mm body dimensions, enabling high-density PCB layouts while maintaining thermal derating of 3.3 mW/K above 74 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures robust operation with standard 5 V rails and tolerance against ripple or droop. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable recognition of TTL logic levels without external biasing. |
| Output Drive | ±8.0 mA at VCC = 4.5 V - supports driving 15 pF loads with <7 ns propagation delay and maintains signal integrity on stubbed buses. |
| Propagation Delay | 3.4 ns (typ, VCC = 5.0 V, CL = 15 pF) - enables use in sub-100 MHz digital interfaces with timing margin. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial and power-conversion control environments. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces risk of handling damage during SMT assembly and field service. |
| Power Dissipation | 250 mW max (Tamb ≤ 74 °C), derates 3.3 mW/K - defines safe continuous power budget in compact XSON6 layout. |
Pinout & Package
XSON6 (SOT886) plastic extremely thin small outline package: 1.0 × 1.45 × 0.5 mm body, no leads, 6 terminals, side-wettable flanks not present (distinct from SOT8065-1), thermal pad absent.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A | Data input - accepts TTL-level signals; overvoltage tolerant to 5.5 V independent of VCC. |
| 2 | OE | Active-low 3-state enable - pulls Y to high-Z when HIGH; must be driven to GND or VCC, not left floating. |
| 3 | GND | Ground reference - return path for all internal currents; requires low-inductance connection to system ground plane. |
| 4 | n.c. | No connection - terminal is internally unconnected; must remain unbonded and unconnected on PCB. |
| 5 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 3 mm of this pin for noise immunity. |
| 6 | Y | Buffered output - provides rail-to-rail CMOS output swing with symmetrical rise/fall times and ±8 mA drive. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V - eliminates need for external level shifters when interfacing with 5 V microcontrollers or legacy peripherals. |
| Overvoltage-tolerant inputs | Withstands up to 5.5 V regardless of VCC setting - enables safe connection to higher-voltage buses without clamping diodes or resistors. |
| Symmetrical output impedance | Rise/fall time matching within 10% (CL = 15 pF) - minimizes duty-cycle distortion in clock distribution or data strobe paths. |
| Low dynamic power dissipation | CPD = 11 pF - limits switching current draw in high-frequency enable/disable cycling, reducing supply noise and heat generation. |
| Extended temperature qualification | Specified from -40 °C to +125 °C - supports deployment in motor drives, PLC I/O modules, and outdoor telecom equipment. |
Applications
| Industrial Backplane Interface | Microcontroller GPIO Expansion |

Use Scenario: Isolating and buffering address/data lines between a 5 V FPGA and 3.3 V ARM Cortex-M7 MCU on a modular PLC carrier board. IC Role / Device Role / Timing Role: Bidirectional bus buffer with 3-state control synchronized to FPGA read/write strobes, enabling shared memory access without contention. Use Value: TTL input compatibility allows direct connection to FPGA I/O banks; 3-state output prevents bus conflicts during DMA transfers. |

IC Role / Device Role / Timing Role: Unidirectional level-translating driver translating 3.3 V logic outputs to full 5 V swing while sourcing/sinking 8 mA per channel. Use Value: Eliminates need for discrete MOSFET translators; overvoltage tolerance protects MCU pins if peripheral powers up first. |
| Legacy System Integration | Test Equipment Signal Conditioning |
|
Use Scenario: Interfacing modern 3.3 V SoC debug ports (SWD/JTAG) with legacy 5 V boundary-scan test fixtures. IC Role / Device Role / Timing Role: 3-state buffer enabling bidirectional signal routing controlled by fixture-side enable logic, supporting IEEE 1149.1 TAP controller handshaking. Use Value: Guaranteed VIH/VIL margins prevent metastability during protocol negotiation; fast tpd ensures TCK timing compliance up to 25 MHz. |
Use Scenario: Conditioning digital trigger and gate signals in automated test equipment where mixed-voltage subsystems coexist. IC Role / Device Role / Timing Role: Low-skew buffer isolating sensitive analog front-end timing generators from noisy digital control logic, with precise enable/disable timing. Use Value: Sub-7 ns tdis/ten ensures clean signal blanking windows; symmetrical output impedance preserves edge fidelity into 50 Ω coaxial traces. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G125GV,125 | SC-74A (SOT753) package: 5-terminal, leaded, larger footprint (3.1 × 1.7 mm), higher thermal resistance (3.8 mW/K derating above 85 °C). | Better manual solderability and rework visibility; less suitable for ultra-dense layouts or automated optical inspection of solder joints. | Select when board assembly uses selective soldering or requires mechanical robustness over miniaturization. |
| SN74LVC1G125DBVR | CMOS input thresholds (VIH = 2.0 V min at VCC = 3.3 V), wider VCC range (1.65–5.5 V), but lacks overvoltage tolerance beyond VCC. | Supports dual-supply systems (e.g., 1.8 V core + 3.3 V I/O); cannot safely interface to 5 V buses unless VCC = 5 V. | Select when operating exclusively at 3.3 V or lower and requiring lowest static current (<1 μA ICC), not mixed-voltage translation. |
Compared with 74AHCT1G125GV,125, the GM variant offers 30% smaller PCB area and improved thermal response; compared with SN74LVC1G125DBVR, it trades universal VCC flexibility for guaranteed 5 V bus interoperability and input overvoltage resilience.

FAQ
What is the maximum allowable input voltage on pin A when VCC = 3.3 V?
The input pins are overvoltage tolerant up to 5.5 V regardless of VCC level. When VCC = 3.3 V, pin A may safely accept DC or transient signals from 0 V to 5.5 V without damage or latch-up, as confirmed in Section 2 and Table 5 of the datasheet.
Can 74AHCT1G125GM,132 drive a 50 Ω transmission line directly?
No - its output is designed for capacitive loads (CL ≤ 50 pF), not 50 Ω resistive termination. Driving a 50 Ω line would exceed ±8 mA output current rating and distort signal edges; a series resistor or dedicated line driver is required for impedance-matched routing.
Is the n.c. pin (terminal 4) required to be grounded or left floating?
Terminal 4 is explicitly designated "not connected" in Table 3 and Fig. 9. It must remain unconnected on the PCB - neither grounded nor tied to any net - as it has no internal bond wire or circuit connection, and grounding it could compromise package integrity or thermal behavior.
How does the 3-state disable timing behave when OE transitions from LOW to HIGH?
When OE rises from LOW to HIGH, output Y transitions to high-impedance within tdis ≤ 9.5 ns (VCC = 5.0 V, CL = 50 pF), measured from 50% OE edge to Y crossing VOH − 0.3 V or VOL + 0.3 V, as defined in Figure 5 and Table 8 for the 74AHCT variant.
