Product details
Overview
74HC2G125GD,125 from Nexperia is a dual 3-state non-inverting buffer/line driver in XSON8 (SOT996-2) package, operating from 2.0 V to 6.0 V, with CMOS-level inputs, ±7.8 mA output drive at VCC = 4.5 V, and propagation delay as low as 8 ns at VCC = 6.0 V. It enables bidirectional bus isolation in digital logic interfaces such as I²C level-shifting, microcontroller GPIO expansion, and memory address/data bus control.
For engineers reviewing the 74HC2G125GD,125 datasheet, 74HC2G125GD,125 pinout, 74HC2G125GD,125 application, or 74HC2G125GD,125 equivalent, key selection criteria include supply voltage range compatibility (2.0–6.0 V), 3-state enable timing (enable/disable < 26 ns), input clamp diode support for overvoltage-tolerant interfacing, and thermal performance in compact XSON8 footprint.
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state output enable (1OE, 2OE). The logic function follows standard HC-series truth table: when nOE = LOW, nY = nA; when nOE = HIGH, nY = high-impedance. Input clamp diodes allow current-limiting resistor-based interface to signals exceeding VCC - critical for mixed-voltage domain bridging.
It operates across industrial and extended temperature ranges (−40 °C to +125 °C), supports dynamic power calculation via CPD (11 pF enabled / 1 pF disabled), and meets JEDEC JESD7A (4.5–5.5 V) and ESD standards (HBM >2000 V, CDM >1000 V). No internal pull-ups or Schmitt-trigger inputs are present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters |
| Propagation Delay (tpd) | 8 ns (max) at VCC = 6.0 V, CL = 50 pF - enables sub-100 MHz bus operation with tight timing margins |
| Output Drive (IO) | ±7.8 mA at VCC = 4.5 V - sufficient to drive 10 LS-TTL loads or 15–20 CMOS inputs |
| Input Clamp Diodes | Present on all inputs - permits safe connection to voltages up to VCC + 0.5 V using series resistors |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive auxiliary circuits and industrial PLC I/O modules |
| ESD Protection | HBM >2000 V, CDM >1000 V - exceeds IEC 61000-4-2 Level 2 for board-level robustness |
| Power Dissipation Cap | 250 mW (Tamb ≤ 96 °C, TSSOP8); derates linearly above - constrains maximum simultaneous switching outputs in thermally constrained layouts |
Pinout & Package
XSON8 (SOT996-2) package: plastic extremely thin small outline no-lead, 8-terminal, 1.35 mm × 1.35 mm body, 0.35 mm pitch, exposed thermal pad, moisture sensitivity level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable for Buffer 1 - drives 1Y into high-Z when HIGH; must be pulled LOW for functional output |
| 2 | 1A | Data input for Buffer 1 - accepts CMOS-level signals; clamped to GND/VCC for overvoltage tolerance |
| 3 | 2Y | Data output for Buffer 2 - 3-state, capable of sourcing/sinking ±7.8 mA at VCC = 4.5 V |
| 4 | GND | Digital ground reference - must be low-inductance connected to PCB ground plane for noise immunity |
| 5 | 2A | Data input for Buffer 2 - electrically identical to 1A; supports independent signal routing |
| 6 | 1Y | Data output for Buffer 1 - non-inverting, high-drive, 3-state output matching 2Y electrical specs |
| 7 | 2OE | Active-low enable for Buffer 2 - independent control allows selective bus segment activation |
| 8 | VCC | Positive supply rail - decoupling capacitor (100 nF) required within 3 mm of pin for stable switching |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (2.0–6.0 V) | Enables single-bom deployment across 3.3 V microcontrollers and 5 V legacy peripherals without voltage translation |
| Input clamp diodes | Permits safe interface to 5 V signals on 3.3 V-powered systems using only series current-limiting resistors |
| Low dynamic power (CPD = 11 pF) | Reduces switching current by >40% vs. older 74HC variants - critical for battery-powered sensor nodes |
| High noise immunity (typ. 45% VCC) | Ensures reliable operation in electrically noisy environments like motor drive control boards |
| −40 °C to +125 °C operation | Validated for use in automotive cabin electronics and industrial edge controllers without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G125DPWR | Lower VCC range (1.65–5.5 V); TTL-compatible inputs; higher ICC (30 μA typ) | Better suited for 1.8 V/3.3 V-only systems; less tolerant of 5 V inputs without external clamping | Select if operating below 2.0 V or requiring guaranteed 1.8 V logic compatibility |
| 74AHC2G125GW,125 | Faster tpd (5.5 ns @ VCC = 5 V); higher output drive (±8 mA); same package and pinout | Preferred for high-speed clock distribution or dense timing-critical PCBs where <6 ns delay is mandatory | Select when propagation delay budget is tighter than 8 ns and supply is stable at 4.5–5.5 V |
Compared with SN74LVC2G125DPWR, the 74HC2G125GD,125 offers broader voltage flexibility and superior overvoltage input tolerance; compared with 74AHC2G125GW,125, it trades 2.5 ns speed for lower dynamic power and wider VCC headroom - making it optimal for mixed-voltage, thermally constrained, or cost-sensitive industrial designs.

FAQ
What is the maximum recommended operating voltage for 74HC2G125GD,125?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 2.0 V to 6.0 V per datasheet Table 6. Operation above 6.0 V risks accelerated parametric drift and reduced long-term reliability, even if within absolute limits. For 5 V systems, VCC = 4.5–5.5 V ensures full specification compliance including VOH/VOL and timing.
Can 74HC2G125GD,125 safely interface a 5 V signal to a 3.3 V powered circuit?
Yes - its input clamp diodes allow connection to voltages up to VCC + 0.5 V. With VCC = 3.3 V, a 5 V input is permissible when a series current-limiting resistor (≥1 kΩ) is used to restrict IIK to ≤±20 mA. This avoids damage and maintains valid logic levels without external level shifters.
Is the XSON8 (SOT996-2) package lead-free and RoHS compliant?
Yes - Nexperia confirms the 74HC2G125GD,125 in SOT996-2 package is fully RoHS-compliant and lead-free per EU Directive 2011/65/EU, with homogeneous lead content < 0.1 wt%. The package uses matte tin (Sn) termination and meets JEDEC J-STD-020 moisture sensitivity level 1 (unlimited floor life at ≤30 °C/60% RH).
Does 74HC2G125GD,125 support hot-swap or live-insertion?
No - the device lacks powered-off protection or Ioff (input/output disable during power-down) functionality. Applying input signals while VCC = 0 V may forward-bias internal protection diodes and cause excessive current flow. Always power VCC before applying input signals in hot-swap scenarios.
