Product details
Overview
74AHCT2G32DP,125 from Nexperia is a dual 2-input OR gate logic IC in TSSOP8 package, operating from 4.5 V to 5.5 V supply, with TTL-compatible inputs, 7 ns typical propagation delay at 5 V/50 pF, and overvoltage-tolerant inputs up to 5.5 V - used for level translation and combinatorial logic in industrial control I/O expansion.
For engineers reviewing the 74AHCT2G32DP,125 datasheet, 74AHCT2G32DP,125 pinout, 74AHCT2G32DP,125 application, or 74AHCT2G32DP,125 equivalent, this device serves as a low-power, high-noise-immunity OR gate for mixed-voltage interface bridging, particularly where 5 V TTL input compatibility and 5 V CMOS output drive are required in space-constrained PCB layouts.
Technical Context
The 74AHCT2G32DP,125 implements two independent OR gates with symmetrical output impedance and balanced propagation delays (tPLH ≈ tPHL). Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure compatibility with legacy 5 V microcontroller GPIOs and bus drivers.
Overvoltage-tolerant inputs (up to 5.5 V regardless of VCC) enable safe interfacing between higher-voltage peripherals and lower-supply logic domains without external clamping. The device is fully specified from −40 °C to +125 °C and supports dynamic operation up to 100 MHz under CL = 15 pF conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input OR gate - provides two independent Boolean OR operations per package |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures stable operation across standard 5 V rail tolerances (±10 %) |
| Propagation Delay | 7.0 ns max at VCC = 5.0 V, CL = 50 pF - enables reliable timing in sub-100 MHz digital control paths |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees TTL-compatible recognition of 5 V logic levels |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads (≤50 pF) |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood, motor control, and industrial ambient environments |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - robust handling during automated assembly and field service |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First OR gate input A - accepts TTL-level signals; overvoltage tolerant to 5.5 V |
| 2 | 1B | First OR gate input B - electrically identical to Pin 1; enables dual-input OR function |
| 3 | 2Y | Second OR gate output - sinks or sources up to ±8 mA; rail-to-rail swing (0 V to VCC) |
| 4 | GND | Ground reference - must be low-impedance connection to minimize switching noise coupling |
| 5 | 2A | Second OR gate input A - independent of first gate; shares same supply and ground |
| 6 | 2B | Second OR gate input B - completes second OR function; no internal crosstalk with Gate 1 |
| 7 | 1Y | First OR gate output - matches Pin 3 in drive strength and voltage compliance |
| 8 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input thresholds | Enables direct interfacing with 5 V microcontrollers and legacy logic without level shifters |
| Overvoltage-tolerant inputs (5.5 V) | Allows safe connection to 5 V buses while operating from lower VCC (e.g., 4.5 V), eliminating external protection diodes |
| Symmetrical output impedance | Ensures matched rise/fall times (<10 % skew) for clean signal edges in timing-critical paths |
| Low ICC (≤40 μA at VCC = 5.5 V) | Reduces static power in always-on subsystems such as watchdog logic or status monitoring circuits |
| Latch-up immunity >100 mA | Guarantees robustness against transient current injection during hot-swap or ESD events |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT2G32DC,125 | VSSOP8 package (2.3 mm width); identical electrical specs but 0.2 mm narrower body and 0.6 mm shorter lead length | Better suited for ultra-dense layouts where 0.7 mm PCB real estate reduction justifies requalification | Select when footprint density outweighs thermal margin - VSSOP8 has slightly lower Ptot derating threshold above 99 °C |
| SN74LVC2G32DBVR | Wider VCC range (1.65–5.5 V); CMOS input thresholds; 3.5 ns tpd at 3.3 V/50 pF; lower drive (±24 mA) | Preferred for mixed 3.3 V/5 V systems requiring single-supply flexibility and faster 3.3 V operation | Choose when interfacing with 3.3 V FPGAs or ARM GPIOs - not drop-in compatible due to VIH/VIL mismatch with TTL |
Compared with 74AHCT2G32DP,125, the DC variant saves board space but trades thermal headroom, while the SN74LVC2G32DBVR adds 3.3 V compatibility at the cost of TTL input support - making it unsuitable for legacy 5 V controller interfaces without redesign.

FAQ
Can 74AHCT2G32DP,125 operate reliably at 4.5 V supply?
Yes. The datasheet specifies guaranteed operation from 4.5 V to 5.5 V for the 74AHCT2G32DP,125 variant, with full performance including VIH ≥ 2.0 V, VOL ≤ 0.55 V at 8 mA, and tpd ≤ 10.0 ns across −40 °C to +125 °C. No derating is required at 4.5 V.
Is the input overvoltage tolerance active when VCC = 0 V?
Yes. Input pins remain overvoltage tolerant up to 5.5 V even with VCC = 0 V, as confirmed in Section 8 (Limiting Values) and Section 2 (Features). This allows safe "hot insertion" into live backplanes or partial-power-down scenarios without damage.
What is the maximum capacitive load this device can drive while maintaining timing specs?
The device is characterized up to 50 pF (Table 8), with tpd ≤ 10.0 ns at VCC = 5.5 V. Driving >50 pF increases propagation delay nonlinearly and may cause marginal setup/hold timing; for >50 pF loads, add series termination or buffer stage per Nexperia Application Note AN10674.
Does 74AHCT2G32DP,125 support mixed-voltage translation between 3.3 V and 5 V domains?
No. As an AHCT device, it requires VCC = 4.5–5.5 V and interprets inputs using TTL thresholds - it cannot accept 3.3 V logic-high as valid VIH (needs ≥2.0 V, but 3.3 V systems often swing only to 2.4–2.7 V under load). Use 74LVC2G32 for true 3.3 V ↔ 5 V bidirectional translation.
