Product details
Overview
74AHCT2G125DP,125 from Nexperia is a dual 3-state buffer/line driver with TTL-compatible inputs and overvoltage-tolerant inputs up to 5.5 V, operating across 4.5–5.5 V supply range, delivering propagation delay as low as 3.4 ns (VCC = 5 V, CL = 15 pF), and specified for industrial temperature range (−40 °C to +125 °C). It enables bidirectional voltage translation in mixed-supply systems such as FPGA I/O interfacing and microcontroller peripheral expansion.
For engineers reviewing the 74AHCT2G125DP,125 datasheet, 74AHCT2G125DP,125 pinout, 74AHCT2G125DP,125 application, or 74AHCT2G125DP,125 equivalent, key selection criteria include TTL-level input compatibility, 3-state output control timing (enable/disable < 8.5 ns), symmetrical drive strength (±8 mA), and TSSOP8 package suitability for high-density PCB layouts.
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state enable (nOE) controlling output impedance. Input logic thresholds are fixed at TTL levels (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), ensuring reliable interfacing with legacy 5 V logic families.
Each buffer provides rail-to-rail CMOS output swing, balanced rise/fall times, and overvoltage-tolerant inputs that accept up to 5.5 V regardless of VCC - enabling safe level-shifting between 3.3 V and 5 V domains without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 5.5 V - Ensures compatibility with standard 5 V logic rails and tolerance against supply ripple. |
| Propagation Delay (tpd) | 3.4 ns typical (VCC = 5 V, CL = 15 pF) - Supports >100 MHz data rates in point-to-point bus applications. |
| Output Drive Strength | ±8 mA (VOH/VOL @ VCC = 4.5 V) - Sufficient to drive 15 pF loads with <1 V ground bounce under fast switching. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows direct connection to 5 V signals even when powered from 3.3 V (not applicable here, but inherent capability). |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor control environments. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Reduces need for external transient suppression in board-level ESD zones. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.65 mm lead pitch, exposed pad not present - optimized for automated assembly and thermal performance in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 (1OE, 2OE) | Active-low output enable | Drives outputs to high-impedance state when HIGH; enables concurrent bus sharing with other 3-state devices. |
| 2, 5 (1A, 2A) | Data input | TTL-compatible inputs accept 0.8 V / 2.0 V thresholds; overvoltage tolerant up to 5.5 V. |
| 3, 6 (2Y, 1Y) | Data output | CMOS push-pull outputs deliver rail-to-rail swing and sink/source ±8 mA at VCC = 4.5 V. |
| 4 | GND | Reference ground for all I/O and internal circuitry; requires low-inductance connection to minimize noise coupling. |
| 8 | VCC | Primary power supply pin; decoupling capacitor (100 nF) recommended within 3 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Symmetrical output impedance | Enables matched rise/fall times (<10% skew), critical for minimizing jitter in clock distribution paths. |
| Balanced propagation delays | Ensures deterministic timing between channels - essential for parallel data bus integrity in microcontroller peripherals. |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs while powered from 4.5–5.5 V - eliminates level-shifters in 5 V system backplanes. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during hot-swap or supply sequencing events. |
| Wide temperature operation | Validated from −40 °C to +125 °C - supports deployment in engine control units and industrial PLC I/O modules. |

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 |
|---|---|---|---|
| 74AHCT2G125DC,125 | VSSOP8 package (2.3 mm width); identical electrical specs and pinout. | Preferred for ultra-high-density PCBs where board area is constrained; slightly lower thermal resistance. | Select when footprint size is prioritized over hand-solderability or thermal mass requirements. |
| SN74LVC2G125DPWR | LVCMOS input thresholds (VIH = 2.0 V @ VCC = 3.3 V); 1.65–5.5 V supply range; same TSSOP8 package. | Supports 1.8 V/2.5 V/3.3 V/5 V mixed-voltage systems; not TTL-input compatible. | Choose only if interfacing with modern low-voltage logic; avoid when legacy 5 V TTL sources are present. |
Compared with 74AHCT2G125DC,125, the DP variant offers greater thermal mass and easier rework due to wider lead pitch; versus SN74LVC2G125DPWR, it ensures guaranteed interoperability with 5 V TTL outputs but lacks sub-3.3 V operation.

FAQ
Is 74AHCT2G125DP,125 pin-compatible with 74AHC2G125DP,125?
Yes - both share identical TSSOP8 pinout and function table, but differ in input threshold behavior: 74AHCT2G125DP,125 uses TTL-compatible inputs (VIH = 2.0 V min), while 74AHC2G125DP,125 uses CMOS thresholds (VIH = 0.7×VCC). Swapping requires verifying source logic family compatibility.
What is the maximum capacitive load this device can drive reliably?
Per datasheet Table 8, propagation delay remains within specification up to 50 pF load capacitance at VCC = 5 V. For loads exceeding 50 pF, output rise/fall times increase linearly; derating is required beyond 75 pF to maintain timing margin in synchronous interfaces.
Does this part support hot-swap or live-insertion?
No - the device lacks powered-off protection or Ioff specification. Applying input signals while VCC = 0 V may cause parasitic conduction through input clamps, risking damage or bus contention. Power sequencing must ensure VCC is stable before asserting inputs.
Can 74AHCT2G125DP,125 be used as a level shifter between 3.3 V and 5 V domains?
Only unidirectionally from 3.3 V input to 5 V output: its TTL inputs accept 3.3 V as valid HIGH (VIH = 2.0 V min), and outputs swing rail-to-rail. However, driving 5 V inputs into this device while powered from 3.3 V violates VCC-dependent operation - use dedicated level translators for bidirectional or reverse-domain shifting.
