Product details
Overview
74HCT2G00DC,125 from Nexperia is a dual 2-input NAND gate in VSSOP8 (SOT765-1) package, operating from 4.5 V to 5.5 V with TTL-compatible inputs, 12 ns typical propagation delay at 4.5 V, and rated for -40 °C to +125 °C. It delivers symmetrical output drive (±4 mA), high noise immunity, and latch-up immunity exceeding 100 mA per JESD78 Class II Level B - used in logic-level translation and digital control sequencing in industrial PLC I/O modules.
For engineers reviewing the 74HCT2G00DC,125 datasheet, 74HCT2G00DC,125 pinout, 74HCT2G00DC,125 application, or 74HCT2G00DC,125 equivalent, key selection criteria include TTL input threshold compatibility (VIH = 2.0 V min), VSSOP8 thermal performance (4.9 mW/K derating above 99 °C), guaranteed operation up to +125 °C, and dual-gate integration for space-constrained board-level logic functions.
Technical Context
This device implements two independent CMOS NAND gates with clamp diodes on all inputs, enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Its TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC = 4.5–5.5 V) ensure direct compatibility with legacy 5 V logic families without level shifters.
Propagation delays are tightly balanced across both gates (tpd = 12–29 ns over temperature and voltage), and output impedance is symmetrical (VOH/VOL specified at ±4 mA), supporting reliable fan-out to multiple CMOS or TTL loads. Static power consumption remains ultra-low (ICC ≤ 20 μA at VCC = 5.5 V, VI = VCC/GND).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures interoperability with standard 5 V systems while maintaining noise margin. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - enables direct connection to TTL outputs without level translation. |
| Propagation Delay | 12 ns typ. (VCC = 4.5 V, Tamb = 25 °C) - supports >30 MHz toggle rates in synchronous logic paths. |
| Output Drive | ±4.0 mA at VCC = 4.5 V - drives 10 LS-TTL loads or 20+ CMOS inputs reliably. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial and extended-range embedded control environments. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces risk of handling damage during SMT assembly and field service. |
| Power Dissipation Cap | 250 mW (Tamb ≤ 125 °C) - sufficient for continuous dual-gate operation in compact VSSOP8 footprint. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | 1A, 2A | First input of Gate 1 and Gate 2 - accepts TTL/CMOS logic levels with integrated clamp diodes. |
| 2, 6 | 1B, 2B | Second input of Gate 1 and Gate 2 - electrically identical to A inputs; supports wired-OR expansion. |
| 3, 7 | 2Y, 1Y | Outputs of Gate 2 and Gate 1 - active-low NAND function; rail-to-rail swing with symmetrical sourcing/sinking. |
| 4 | GND | Digital ground reference - must be low-impedance return path for both gates' switching currents. |
| 8 | VCC | Positive supply - decoupling capacitor (100 nF) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | Operates from 4.5 V to 5.5 V - eliminates need for dedicated 5 V regulators in mixed-voltage systems. |
| TTL-Compatible Inputs | VIH ≥ 2.0 V, VIL ≤ 0.8 V - interfaces directly with 74LS, 74F, and microcontroller GPIO without external biasing. |
| Balanced Propagation Delays | tpd matching < 3 ns between gates - critical for glitch-free enable/disable timing in dual-control paths. |
| Latch-Up Immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
| High Noise Immunity | ΔVNS ≥ 0.4 V (VCC = 5 V) - rejects EMI-induced false triggering in noisy industrial environments. |
Applications

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 |
|---|---|---|---|
| SN74LVC2G00DCKR | Lower VCC range (1.65–5.5 V); CMOS inputs only (VIH = 70% VCC); 3.7 ns tpd at 3.3 V. | Optimized for 3.3 V systems; unsuitable for direct TTL interfacing without pull-ups. | Select when operating at 3.3 V or lower and interfacing exclusively with CMOS outputs. |
| 74AHC2G00DC,125 | Wider VCC (2–5.5 V); CMOS inputs; 5.2 ns tpd at 5 V; higher drive (±8 mA). | Higher speed and drive, but lacks TTL input compatibility - requires level shifting with 5 V TTL sources. | Select when maximum speed and output strength are prioritized over TTL input support. |

FAQ
What is the maximum recommended supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V. Operation above 5.5 V voids parametric guarantees and risks accelerated aging due to increased junction stress - sustained use beyond 5.5 V is not supported per JEDEC JESD7A compliance.
Can 74HCT2G00DC,125 drive a 50 pF capacitive load at 10 MHz?
Yes: with CPD = 10 pF and IO = ±4 mA, the device sustains clean 10 MHz square waves into 50 pF loads at VCC = 4.5 V. Measured tt = 19 ns (max) ensures <10% rise/fall time degradation, and VOH/VOL remain within spec (≥4.13 V / ≤0.33 V) under those conditions.
Is this part qualified for automotive applications?
No - 74HCT2G00DC,125 is not AEC-Q100 qualified and carries no automotive grade designation. It is rated for industrial temperature (-40 °C to +125 °C) but lacks automotive-specific stress testing, failure rate reporting, or PPAP documentation required for vehicle ECUs or ADAS subsystems.
How does the input clamp diode affect external resistor selection?
Clamp diodes allow safe overvoltage tolerance up to VCC + 0.5 V. When interfacing to 12 V signals, a series current-limiting resistor ≥560 Ω ensures IIK ≤ ±20 mA (absolute max), preventing diode thermal runaway. Resistor value is calculated as (12 V − VCC − 0.7 V) / 20 mA.
