Product details
Overview
74AHCT2G32DC,125 from Nexperia is a dual 2-input OR gate in VSSOP8 (SOT765-1) 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 logic combining in industrial control I/O expansion.
For engineers reviewing the 74AHCT2G32DC,125 datasheet, 74AHCT2G32DC,125 pinout, 74AHCT2G32DC,125 application, or 74AHCT2G32DC,125 equivalent, this device supports mixed-voltage interface design, requires no external level shifters between 3.3 V and 5 V domains, delivers symmetrical output drive (±8 mA), and maintains guaranteed operation across -40 °C to +125 °C.
Technical Context
This device implements two independent OR logic functions with true TTL input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V TTL outputs while powered from 5 V rails. Its overvoltage-tolerant inputs accept up to 5.5 V regardless of VCC, supporting safe signal injection during power sequencing.
Each gate exhibits matched propagation delays (tPLH/tPHL ≤ 9.0 ns max at VCC = 5 V, CL = 50 pF, -40 °C to +125 °C), low static current (ICC ≤ 40 μA max at VCC = 5.5 V), and robust ESD protection (HBM > 2000 V, CDM > 1000 V), making it suitable for noise-prone industrial PCBs with hot-swap or partial-power-up conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input OR gates - enables compact implementation of parallel OR logic without external gating. |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V systems and tolerance against rail droop. |
| Input Threshold Type | TTL-compatible (VIH ≥ 2.0 V, VIL ≤ 0.8 V) - allows direct connection to 5 V TTL outputs without pull-ups or translators. |
| Propagation Delay | ≤ 9.0 ns max (VCC = 5 V, CL = 50 pF, -40 °C to +125 °C) - supports timing-critical combinational logic in real-time control paths. |
| Output Drive Strength | ±8 mA at VOH/VOL - provides sufficient fan-out for driving multiple CMOS/TTL inputs or small capacitive loads (≤ 50 pF). |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, motor drive, and industrial automation environments. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and board assembly. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin pitch 0.5 mm; exposed pad not present; RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First OR gate input A - accepts TTL-level signals; overvoltage tolerant up to 5.5 V. |
| 2 | 1B | First OR gate input B - electrically identical to 1A; enables dual-input OR function per gate. |
| 3 | 1Y | First OR gate output Y - drives downstream logic with symmetrical rise/fall times and ±8 mA capability. |
| 4 | GND | Ground reference - must be connected to system 0 V plane; shared return for both gates. |
| 5 | 2A | Second OR gate input A - independent of first gate; supports concurrent OR operations. |
| 6 | 2B | Second OR gate input B - matches 1B functionality; no internal coupling between gates. |
| 7 | 2Y | Second OR gate output Y - isolated output node; same electrical specs as 1Y. |
| 8 | VCC | Positive supply - powers both gates; decoupling capacitor (100 nF) recommended within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Accepts up to 5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-rail systems. |
| Wide temperature range | Specified from -40 °C to +125 °C - supports deployment in automotive engine compartments and industrial PLCs. |
| Symmetrical output impedance | Matched rise/fall times (tPLH ≈ tPHL) - minimizes duty cycle distortion in clocked OR applications. |
| Low static power consumption | ICC ≤ 40 μA max at VCC = 5.5 V - reduces quiescent current in always-on monitoring circuits. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overvoltage events. |
Applications
| Industrial I/O Expansion | Legacy System Interface |
|---|---|
|
Use Scenario: Adding discrete digital input channels to a microcontroller-based PLC module with existing 5 V TTL sensor outputs and 5 V supply rail. IC Role / Device Role / Timing Role: OR gate performing wired-OR aggregation of multiple alarm signals before feeding into a single MCU interrupt pin. Use Value: Eliminates need for external level-shifting ICs by accepting 5 V TTL inputs directly while operating on 5 V VCC, reducing BOM count and layout area. |
Use Scenario: Interfacing a modern 3.3 V FPGA I/O bank to legacy 5 V peripheral address/data bus lines requiring active-high enable logic. IC Role / Device Role / Timing Role: Translating 3.3 V FPGA output signals to 5 V-compatible logic levels using overvoltage-tolerant inputs and 5 V VCC-powered outputs. Use Value: Enables safe bidirectional voltage translation without direction control pins or external resistors, leveraging input overvoltage tolerance and TTL input thresholds. |
| Motor Control Safety Logic | Power Sequencing Monitor |
|
Use Scenario: Combining multiple hardware fault signals (overcurrent, overtemperature, stall detection) in a brushless DC motor driver before disabling gate drivers. IC Role / Device Role / Timing Role: Fast-response OR gate ensuring worst-case propagation delay ≤ 9 ns to meet functional safety timing constraints (IEC 61800-5-2). Use Value: Guarantees sub-10 ns fault propagation under full temperature range (-40 °C to +125 °C), critical for SIL-2 compliant shutdown paths. |
Use Scenario: Monitoring power-good status from multiple DC-DC converters (5 V, 3.3 V, 1.8 V) to generate a system-ready signal only when all rails are stable. IC Role / Device Role / Timing Role: OR gate detecting any rail failure (active-low PG signals inverted externally) and asserting a global fault flag. Use Value: Provides deterministic startup sequencing feedback with known delay budget (≤ 9 ns), simplifying timing analysis in multi-rail embedded systems. |
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 |
|---|---|---|---|
| 74AHC2G32DC,125 | CMOS input thresholds (VIH = 3.85 V @ VCC = 5.5 V); wider supply range (2.0–5.5 V) | Better suited for 3.3 V–5 V mixed systems where input signals track VCC | Select when interfacing with CMOS outputs or requiring lower VCC operation down to 2.0 V |
| SN74LVC2G32DBVR | 3.3 V nominal supply (1.65–5.5 V); higher drive (±24 mA); different pinout (1A/1B/1Y/GND/2Y/2B/2A/VCC) | Requires PCB redesign; superior drive for heavy capacitive loads but less tolerant of 5 V-only signal sources | Choose for high-speed 3.3 V systems needing stronger output drive and tighter AC specs |

FAQ
Is 74AHCT2G32DC,125 compatible with 3.3 V input signals?
No - the 74AHCT2G32DC,125 has TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) optimized for 5 V logic families. A 3.3 V signal may not reliably exceed VIH at VCC = 5 V due to process variation and noise margin erosion; use 74AHC2G32DC,125 for guaranteed 3.3 V input recognition.
What is the maximum capacitive load this device can drive?
The device is characterized up to 50 pF load capacitance with guaranteed timing (tpd ≤ 9.0 ns). Driving >50 pF increases propagation delay nonlinearly and may cause marginal setup/hold timing; for >100 pF loads, add a buffer stage or select a higher-drive device like SN74LVC2G32DBVR.
Does this part support hot insertion in live backplanes?
Yes - its overvoltage-tolerant inputs (up to 5.5 V) and latch-up immunity (>100 mA per JESD78 Class II Level A) allow safe connection to powered-backplane signals during hot-swap operations, provided VCC is ramped before signal application per manufacturer guidelines.
Can I use this device to replace obsolete 74LS32 in existing designs?
Yes - the 74AHCT2G32DC,125 matches 74LS32's TTL input thresholds, 5 V operation, and dual 2-input OR function, while offering lower power, faster speed (7 ns vs. 15 ns), and improved noise immunity. Pinout is identical in VSSOP8, enabling drop-in replacement with no layout changes.
