Product details
Overview
74AHCT2G00GD,125 from Nexperia is a dual 2-input NAND gate IC with TTL-compatible input thresholds, operating at 4.5 V to 5.5 V supply voltage, delivering propagation delays as low as 3.6 ns (typ.) at VCC = 5.0 V and CL = 15 pF, and rated for -40 °C to +125 °C ambient temperature - used in logic-level translation and digital control signal conditioning in industrial PLC I/O modules.
For engineers reviewing the 74AHCT2G00GD,125 datasheet, 74AHCT2G00GD,125 pinout, 74AHCT2G00GD,125 application, or 74AHCT2G00GD,125 equivalent, key selection factors include its 8-pin XSON package footprint, TTL input compatibility, guaranteed 8 mA output drive strength at 5 V, and operation across extended industrial temperature range without derating.
Technical Context
This device implements two independent CMOS NAND gates with TTL-level input switching thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V), enabling direct interfacing with legacy 5 V TTL logic families while maintaining low static current (ICC ≤ 10 μA at VCC = 5.5 V) and high noise immunity (VNH/VNL > 0.7 V at VCC = 5 V).
Its dynamic performance is characterized by matched tPLH/tPHL propagation delays, symmetrical output impedance, and power dissipation capacitance of 18 pF per gate - supporting reliable timing in synchronous control paths where fan-out and transition integrity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input NAND gate - provides two independent Boolean NOT-AND operations in one package |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and mixed-voltage digital systems |
| Propagation Delay | 3.6 ns (typ.) at VCC = 5.0 V, CL = 15 pF - enables use in sub-100 MHz clock-domain control logic |
| Output Drive | ±8 mA at VCC = 4.5 V - supports driving 10+ 74-series TTL inputs or moderate capacitive loads |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial and motor-control environments |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - matches TTL logic levels for seamless interface without level shifters |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 Level 2 for board-level robustness |
Pinout & Package
The 74AHCT2G00GD,125 is housed in an 8-pin XSON package (SOT996-2), measuring 1.35 mm × 1.35 mm with 0.5 mm pitch and no exposed pad - optimized for ultra-compact PCB layouts in space-constrained embedded controllers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First NAND gate input A - accepts TTL-compatible logic signals |
| 2 | 1B | First NAND gate input B - paired with 1A to generate inverted AND output at 1Y |
| 3 | 1Y | First NAND gate output - drives downstream logic with ±8 mA capability |
| 4 | GND | Ground reference - must be low-impedance connection to minimize switching noise |
| 5 | 2Y | Second NAND gate output - electrically isolated from 1Y; shares same VCC/GND |
| 6 | 2B | Second NAND gate input B - independent of first gate; supports dual logic functions |
| 7 | 2A | Second NAND gate input A - enables concurrent 2-input NAND evaluation in same footprint |
| 8 | VCC | Positive supply - requires local 100 nF decoupling adjacent to pin for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Enables direct connection to legacy 5 V microcontrollers and peripheral ICs without level-shifting circuitry |
| Symmetrical output impedance | Ensures matched rise/fall times (<1 ns skew) for clean signal edges in timing-critical paths |
| Balanced propagation delays | Guarantees identical tPLH/tPHL between both gates - critical for synchronized enable/disable functions |
| Low static power | ICC ≤ 10 μA at VCC = 5.5 V - reduces quiescent load on power rails in always-on monitoring circuits |
| Extended temperature rating | Validated operation from -40 °C to +125 °C - suitable for motor drive gate driver logic and industrial sensor interfaces |
Applications
| Industrial PLC I/O Modules | Motor Control Logic Sequencing |
|---|---|
Use Scenario: Signal conditioning and enable/disable gating of analog-to-digital converter trigger lines in programmable logic controller backplanes. IC Role / Device Role / Timing Role: Dual NAND gate performs active-low enable logic and synchronizes sampling pulses across multiple ADC channels. Use Value: Matches TTL input thresholds of legacy PLC CPUs and delivers sub-4 ns delay consistency to maintain <100 ns inter-channel timing alignment. | Use Scenario: Generating complementary gate-drive enable signals for half-bridge MOSFET drivers in variable-frequency drives. IC Role / Device Role / Timing Role: Provides logic-level NAND-based dead-time insertion and fault-lockout coordination between upper/lower switch controls. Use Value: Symmetrical output drive and matched propagation delays prevent shoot-through by ensuring precise, jitter-free timing margins. |
| Embedded Sensor Interface Boards | Legacy Microcontroller Peripheral Expansion |
Use Scenario: Combining interrupt request signals from multiple environmental sensors (temperature, humidity, pressure) into a single shared MCU interrupt line. IC Role / Device Role / Timing Role: Acts as wired-OR logic combiner via NAND-inversion, reducing pin count on resource-constrained MCUs. Use Value: Low input leakage (<1.0 μA) prevents false triggering; 125 °C rating supports placement near heat-generating sensor front-ends. | Use Scenario: Expanding GPIO functionality of 8-bit microcontrollers (e.g., 8051 derivatives) to manage additional status LEDs and pushbutton debouncing logic. IC Role / Device Role / Timing Role: Supplies compact, low-power combinational logic for user-interface state encoding and visual feedback control. Use Value: XSON8 package (1.35 mm²) saves >70% board area vs. SOIC-8; TTL compatibility eliminates external pull-up resistors. |
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 |
|---|---|---|---|
| 74AHCT2G00DC/SOT765-1 | VSSOP8 package (2.3 mm body width); identical electrical specs and pinout | Larger footprint but easier manual soldering and probe access during debug | Select when board assembly uses pick-and-place with vision-assisted alignment or requires rework accessibility |
| SN74LVC2G00DBVR | Wider supply range (1.65–5.5 V); LVTTL input thresholds; different pinout (1A/1B/2A/2B on left side) | Supports 3.3 V and mixed-voltage systems; not drop-in compatible due to pin rearrangement | Choose for new designs targeting 3.3 V domains or requiring broader voltage flexibility, provided layout revision is acceptable |
Compared with 74AHCT2G00DC and SN74LVC2G00DBVR, the 74AHCT2G00GD,125 offers the smallest PCB footprint (1.35 mm × 1.35 mm), maintains strict TTL input compatibility at 5 V, and delivers identical timing performance - making it optimal for miniaturized industrial control modules where space and legacy interface fidelity are primary constraints.

FAQ
What is the maximum recommended operating frequency for 74AHCT2G00GD,125?
The device does not specify a maximum clock frequency, but its typical propagation delay of 3.6 ns at 5 V and 15 pF load implies reliable operation up to approximately 100 MHz in simple combinatorial paths. Actual usable frequency depends on system-level loading, trace inductance, and fan-out; for synchronous applications, ensure setup/hold margins exceed 2× the worst-case tpd.
Can 74AHCT2G00GD,125 operate at 3.3 V supply?
No - the AHCT variant is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds fall outside specification (VIH min = 2.0 V requires ≥4.5 V for guaranteed margin), and output drive degrades significantly. For 3.3 V systems, consider the pin-compatible 74LVC2G00 or 74AHC2G00 variants instead.
Is the XSON8 package (SOT996-2) lead-free and RoHS compliant?
Yes - Nexperia confirms the 74AHCT2G00GD,125 is manufactured using lead-free die attach and termination materials, fully compliant with EU RoHS Directive 2011/65/EU and REACH SVHC regulations, with homogeneous lead content below 0.1 wt% and no intentionally added restricted substances.
Does this device require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs must be terminated to VCC or GND to prevent floating states that cause increased ICC, oscillation, or ESD susceptibility. For TTL-compatible inputs, connecting to VCC via a 10 kΩ resistor is preferred; direct tie to VCC or GND is acceptable if routing permits, as input leakage remains below 0.1 μA.
