Product details
Overview
74HC2G125DP,125 from Nexperia is a dual 3-state buffer/line driver in TSSOP8 (SOT505-2) package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, ±7.8 mA output drive at 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 microcontroller I/O expansion and level-translated data routing.
For engineers reviewing the 74HC2G125DP,125 datasheet, 74HC2G125DP,125 pinout, 74HC2G125DP,125 application, or 74HC2G125DP,125 equivalent, key selection criteria include 3-state control timing (enable/disable <26 ns), input clamp diode support for overvoltage-tolerant interfacing, guaranteed operation up to +125 °C, and compatibility with both HC and HCT logic families via pin-compatible variants.
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state enable (1OE, 2OE) controlling high-impedance output states. Input clamping diodes allow safe interface to voltages exceeding VCC when used with current-limiting resistors.
It supports wide ambient temperature range (–40 °C to +125 °C), meets JESD7A (4.5–5.5 V), and delivers high noise immunity with VIH/VIL thresholds defined across full VCC range - e.g., VIH ≥ 4.2 V at VCC = 6.0 V for HC version.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - supports mixed-voltage system interfacing including 3.3 V and 5 V logic domains. |
| Propagation Delay | 8 ns (typ) at VCC = 6.0 V - enables reliable operation in high-speed digital control paths up to ~50 MHz. |
| Output Drive | ±7.8 mA at VCC = 4.5 V - sufficient to drive standard TTL loads or multiple CMOS inputs without external buffering. |
| Enable/Disable Time | 8 ns (ten), 10 ns (tdis) at VCC = 6.0 V - ensures precise bus arbitration timing in shared-data applications. |
| Input Clamp Diodes | Integrated - permits safe connection to signals up to VCC + 0.5 V using series resistors, simplifying level-shifting design. |
| Operating Temperature | –40 °C to +125 °C - qualified for industrial and extended-temperature embedded control environments. |
| ESD Protection | HBM >2000 V, CDM >1000 V - enhances robustness during board assembly and field operation. |
Pinout & Package
TSSOP8 (SOT505-2) package: plastic thin shrink small outline, 8 leads, body width 3 mm, lead length 0.5 mm, pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 | 1OE, 2OE | Active-low 3-state enable inputs - assert LOW to enable respective buffer output; HIGH places output in high-Z state. |
| 2, 5 | 1A, 2A | Data inputs - non-inverting logic inputs driving corresponding outputs; tolerate overvoltage via internal clamp diodes. |
| 3, 6 | 2Y, 1Y | Data outputs - buffered, 3-state outputs capable of sourcing/sinking ±7.8 mA at 4.5 V. |
| 4 | GND | Ground reference - must be connected to system 0 V plane; serves as return path for all input/output currents. |
| 8 | VCC | Supply voltage - powers internal logic and output stages; decoupling capacitor (100 nF) recommended near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2.0 V to 6.0 V - eliminates need for separate voltage translators when interfacing 3.3 V controllers to 5 V peripherals. |
| Input Clamp Diodes | Integrated on all inputs - allows direct connection to higher-voltage buses (e.g., 12 V sensor lines) with only series current-limiting resistors. |
| High Noise Immunity | VIH/VIL margins exceed 30% of VCC across full operating range - reduces susceptibility to ground bounce and crosstalk in dense PCB layouts. |
| Latch-up Performance | >100 mA per JESD78 Class II Level B - ensures robustness against transient current faults in industrial power environments. |
| Low Dynamic Power | CPD = 11 pF (enabled), 1 pF (disabled) - minimizes switching power consumption in battery-powered or thermally constrained systems. |
Applications
| Microcontroller I/O Expansion | Industrial Bus Isolation |
|---|---|

IC Role / Device Role / Timing Role: Dual 3-state buffer isolates MCU pins from bus loading; enables time-multiplexed access via OE control synchronized to SPI/I²C timing. Use Value: Eliminates need for discrete MOSFET switches or complex CPLD logic while maintaining signal integrity and timing predictability. |
Use Scenario: Isolating Modbus RTU RS-485 transceiver data lines from PLC CPU backplane to prevent ground loop interference and fault propagation. IC Role / Device Role / Timing Role: Acts as direction-controlled line driver between CPU UART and transceiver DE/RE control lines; enables half-duplex bus arbitration. Use Value: Provides clean, fast-enable/disable transitions (<26 ns) critical for avoiding bus contention during master/slave handshaking. |
| Level-Shifted Sensor Interface | Legacy System Signal Conditioning |
|
Use Scenario: Interfacing a 12 V analog front-end (AFE) with overvoltage-tolerant digital status outputs to a 3.3 V FPGA I/O bank. IC Role / Device Role / Timing Role: Buffer accepts 12 V inputs via internal clamp diodes and series resistors; outputs clean 3.3 V CMOS levels to FPGA. Use Value: Removes requirement for external level shifters or optocouplers, reducing BOM cost and PCB area while preserving timing accuracy. |
Use Scenario: Replacing obsolete 74LS244 in a legacy industrial controller where TTL-compatible inputs and 5 V CMOS outputs are required.

Use Value: Enables long-term supply continuity without redesign; maintains backward compatibility while improving thermal performance and ESD resilience. |
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 |
|---|---|---|---|
| 74HCT2G125DP,125 | TTL-compatible inputs (VIH = 2.0 V min at VCC = 4.5–5.5 V); otherwise identical pinout, timing, and packaging. | Required when interfacing legacy 5 V TTL outputs; not suitable for pure CMOS systems with weak drive strength. | Select when driving from standard 5 V TTL sources; verify input transition rates meet Δt/ΔV spec (≥139 ns/V at 4.5 V). |
| SN74LVC2G125DPWR | Lower VCC range (1.65–5.5 V); higher drive (±24 mA); different pinout (1OE/2OE on pins 1/5 vs. 1/7); no input clamp diodes. | Suitable for ultra-low-voltage portable designs but lacks overvoltage tolerance; requires careful layout for ESD protection. | Prefer for battery-powered applications needing higher drive or sub-2 V operation; avoid where input overvoltage risk exists. |
Compared with 74HCT2G125DP,125, the HC variant offers superior noise margin in mixed-signal systems; compared with SN74LVC2G125DPWR, it trades drive strength and voltage flexibility for built-in overvoltage protection and broader industrial temperature compliance.

FAQ
What is the maximum clock/data rate supported by the 74HC2G125DP,125?
The device does not operate as a clocked element but as a combinatorial buffer. Its 8 ns typical propagation delay at VCC = 6.0 V supports reliable data throughput up to approximately 50 MHz in synchronous bus applications, assuming setup/hold margins and PCB trace delays are accounted for in system timing analysis.
Can the 74HC2G125DP,125 safely interface with 12 V signals?
Yes - its integrated input clamp diodes allow connection to voltages up to VCC + 0.5 V. When paired with a series current-limiting resistor (e.g., 10 kΩ for 12 V → 3.3 V), it safely translates 12 V logic levels to CMOS-compatible inputs without external components.
Is the 74HC2G125DP,125 pin-compatible with the 74HCT2G125DP,125?
Yes - both share identical TSSOP8 (SOT505-2) pinout, package dimensions, and functional pin assignments. The only difference is input threshold compatibility: HC uses CMOS-level inputs, while HCT matches TTL logic levels, making them direct replacements depending on source driver type.
Does the 74HC2G125DP,125 require external pull-up or pull-down resistors on its enable inputs?
No - the 1OE and 2OE inputs are standard CMOS with negligible leakage (±1.0 μA max). However, in floating-input scenarios, a pull-down resistor (e.g., 100 kΩ to GND) is recommended to ensure defined inactive (HIGH) state and prevent unintended output activation due to noise coupling.
