Product details
Overview
74AHCT2G00DP,125 from Nexperia is a dual 2-input NAND gate IC in TSSOP8 package, operating at 4.5 V to 5.5 V with TTL-compatible input thresholds, 7 ns typical propagation delay (CL = 15 pF, VCC = 5 V), ±8 mA output drive, and rated for -40 °C to +125 °C ambient operation - used in digital logic interfacing, level translation, and control signal conditioning in industrial PLC I/O modules.
For engineers reviewing the 74AHCT2G00DP,125 datasheet, 74AHCT2G00DP,125 pinout, 74AHCT2G00DP,125 application, or 74AHCT2G00DP,125 equivalent, key selection factors include TTL-level input compatibility, guaranteed 125 °C operation, symmetrical output impedance, low static current (<10 μA at VCC = 5.5 V), and TSSOP8 thermal performance with 4.6 mW/K derating above 96 °C.
Technical Context
This device implements two independent CMOS NAND gates with hard-wired TTL-compatible input voltage thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V), enabling direct interface with legacy 5 V TTL logic families without level shifters. Its symmetrical output structure ensures matched rise/fall times under capacitive loads up to 50 pF.
Designed for high-noise industrial environments, it features HBM ESD protection exceeding 2000 V and CDM protection exceeding 1000 V, while maintaining stable operation across full automotive-grade temperature range (-40 °C to +125 °C) with no output voltage degradation at temperature extremes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input NAND gate; enables compact logic synthesis for enable/inhibit control paths |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with regulated 5 V rails and rejects supply noise below 4.5 V |
| Propagation Delay | 3.6 ns (typ) / 8.0 ns (max) at CL = 15 pF, VCC = 5 V - supports >100 MHz toggle rates in buffered configurations |
| Output Drive | ±8 mA at VOH/VOL - sufficient to directly drive multiple 74-series inputs or small LED indicators |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees robust recognition of TTL logic levels across temperature |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial control and motor drive feedback circuits |
| Static Supply Current | ≤10 μA at VCC = 5.5 V - enables use in always-on monitoring subsystems without battery drain penalty |

| 3, 7 (1Y, 2Y) | Output of Gate 1 / Output of Gate 2 | Push-pull CMOS outputs; capable of sourcing/sinking 8 mA with rail-to-rail swing |
| 4 | GND | Ground reference for all inputs/outputs; must be low-impedance connection to minimize noise coupling |
| 8 | VCC | Positive supply; decoupling capacitor (100 nF) required within 5 mm for stable high-speed switching |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Enables plug-in replacement of 74LS00 without redesigning input biasing or pull-up networks |
| Symmetrical output impedance | Ensures matched rise/fall times (tPLH ≈ tPHL), critical for clockless synchronous logic timing |

Applications
| Industrial PLC Digital I/O | Motor Drive Enable Logic |
|---|---|
Use Scenario: Isolating and conditioning digital command signals from microcontroller GPIO to optocoupled output stages in programmable logic controllers. IC Role / Device Role / Timing Role: Dual NAND gate performing active-low enable inversion and signal gating before isolation barrier. Use Value: Eliminates need for discrete inverters and AND gates; TTL input compatibility ensures reliable interpretation of 5 V controller outputs even with ±10 % supply variation. | Use Scenario: Generating complementary gate-drive enable signals for half-bridge MOSFET drivers in BLDC motor inverters. IC Role / Device Role / Timing Role: Logic-level combiner ensuring shoot-through prevention by enforcing mutual exclusion between high-side and low-side enable paths. Use Value: Propagation delay matching <1 ns between gates prevents timing skew that could cause cross-conduction; 125 °C rating allows PCB placement near heatsinks. |
| Legacy System Interface Adapter | Power Sequencing Controller |

IC Role / Device Role / Timing Role: Level-translating NAND gate implementing handshake protocol logic (STB ∧ BUSY) with TTL threshold alignment. Use Value: Direct 5 V input compatibility avoids external resistor networks; low input leakage (<0.1 μA) prevents false triggering on high-impedance bus lines. | Use Scenario: Coordinating power-up sequence of FPGA, memory, and analog subsystems using reset and enable signals. IC Role / Device Role / Timing Role: Glue logic element combining POR, watchdog, and software reset to generate synchronized power-enable pulses. Use Value: Guaranteed 125 °C operation ensures reliability during extended thermal stress testing; symmetrical delays prevent metastability in multi-signal arbitration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G00DBVR | CMOS input thresholds (VIH ≥ 0.7×VCC), 1.65–5.5 V supply range, 3.7 ns max tpd at 3.3 V | Optimized for mixed-voltage 3.3 V/2.5 V systems; not TTL-compatible | Select when interfacing with LVTTL or LVCMOS logic and wider supply flexibility is needed |
| 74AHC2G00DP,125 | CMOS input thresholds, 2.0–5.5 V supply, 10.5 ns max tpd at 3.3 V, same TSSOP8 package | Supports lower supply voltages but lacks TTL input compatibility | Select when system uses pure CMOS signaling and requires sub-3 V operation capability |
Compared with SN74LVC2G00DBVR and 74AHC2G00DP,125, the 74AHCT2G00DP,125 uniquely delivers guaranteed TTL-level recognition at 5 V while maintaining identical pinout and thermal profile - making it the only drop-in solution for upgrading legacy 74LS00-based designs without modifying input drive circuitry or layout.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The device is qualified for operation up to +125 °C ambient temperature, and its absolute maximum junction temperature is +150 °C. With the TSSOP8 package's thermal resistance (RθJA ≈ 120 K/W), sustained power dissipation must remain below 208 mW to avoid exceeding this limit - consistent with the 250 mW total power dissipation rating derated linearly above 96 °C.
Can 74AHCT2G00DP,125 operate reliably at 3.3 V supply?
No - the AHCT variant is specified only for 4.5 V to 5.5 V supply. At 3.3 V, input thresholds fall outside specification (VIH min = 2.0 V becomes marginal), and output drive degrades significantly. For 3.3 V systems, use the pin-compatible 74AHC2G00DP,125 or SN74LVC2G00DBVR instead.
Is this device suitable for automotive applications?
No - although rated for -40 °C to +125 °C, the 74AHCT2G00DP,125 is not AEC-Q100 qualified and lacks automotive-specific reliability testing, traceability, or failure rate reporting. Nexperia explicitly states non-automotive qualification in its legal disclaimers; use only in industrial or commercial equipment.
How does the symmetrical output impedance improve system timing?
Symmetrical output impedance ensures nearly identical rise (tPLH) and fall (tPHL) propagation delays - measured at 3.6 ns (typ) each at VCC = 5 V. This balance eliminates duty-cycle distortion in clocked or PWM-derived signals, preventing setup/hold violations in downstream flip-flops and reducing jitter in edge-sensitive interfaces.
