Product details
Overview
74HCT2G00DP,125 from Nexperia is a dual 2-input NAND gate logic IC with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5.0 V), 4.5–5.5 V supply range, propagation delay of 12–29 ns, ±4 mA output drive, and TSSOP8 (SOT505-2) package rated for -40 °C to +125 °C operation. It performs basic combinational logic in digital control subsystems such as power sequencers and interface glue logic.
For engineers reviewing the 74HCT2G00DP,125 datasheet, 74HCT2G00DP,125 pinout, 74HCT2G00DP,125 application, or 74HCT2G00DP,125 equivalent, key selection criteria include TTL-level input compatibility, guaranteed operation across automotive-grade temperature range, low dynamic power (CPD = 10 pF), symmetrical output impedance, and IEC/ANSI ESD robustness (HBM > 2000 V).
Technical Context
This device implements two independent NAND gates using CMOS silicon technology with TTL-level input stage design, enabling direct interfacing with legacy 5 V TTL outputs without level translation. Each gate features clamp diodes on inputs for overvoltage tolerance when used with current-limiting resistors.
Propagation delays are tightly balanced between high-to-low (tPHL) and low-to-high (tPLH) transitions, and output transition times (tTLH/tTHL) remain consistent across temperature and supply voltage, supporting reliable timing in synchronous control paths and state-machine enable logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input NAND gate; enables compact Boolean logic implementation without external gating. |
| Supply Voltage Range | 4.5 V to 5.5 V; ensures compatibility with standard 5 V digital rails and noise margin compliance per JEDEC JESD8C. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V (VCC = 4.5–5.5 V); guarantees reliable recognition of TTL-family logic levels. |
| Output Drive | ±4.0 mA at VCC = 4.5 V; sufficient to drive 10 LSTTL loads or moderate capacitive loads (< 50 pF) directly. |
| Propagation Delay | 12–29 ns (typ/max at VCC = 4.5 V); supports operation up to ~20 MHz toggle frequency in non-critical timing paths. |
| ESD Rating | HBM > 2000 V, CDM > 1000 V; meets industrial handling requirements without additional protection circuitry. |
| Operating Temperature | -40 °C to +125 °C; qualified for under-hood automotive, industrial PLC, and high-reliability embedded control environments. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2), 8 leads, body width 3 mm, lead length 0.5 mm, pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First NAND gate input A; accepts TTL-level signals directly with no level shifter required. |
| 2 | 1B | First NAND gate input B; internally clamped to support safe interfacing above VCC via series resistor. |
| 3 | 2Y | Second NAND gate output Y; provides rail-to-rail CMOS swing compatible with downstream 5 V logic. |
| 4 | GND | Ground reference; must be low-impedance connection to minimize switching noise coupling. |
| 5 | 2A | Second NAND gate input A; electrically isolated from 1A/1B; enables independent logic path routing. |
| 6 | 2B | Second NAND gate input B; shares same input structure and threshold as pins 1 and 2. |
| 7 | 1Y | First NAND gate output Y; symmetrical rise/fall times ensure minimal duty-cycle distortion. |
| 8 | VCC | Positive supply; decoupling capacitor (100 nF ceramic) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Enables direct connection to legacy 5 V microcontrollers, FPGAs, and peripheral ICs without level-shifting components. |
| Symmetrical output impedance | Ensures matched rise/fall times (6–19 ns typ), critical for glitch-free enable/disable sequencing in power management circuits. |
| Clamp diode protected inputs | Allows safe interface to voltages exceeding VCC when used with current-limiting resistors-reduces need for external TVS or Zener clamps. |
| High noise immunity | Input hysteresis and 0.4 V noise margin at VCC = 5 V suppress false triggering in electrically noisy industrial environments. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B, preventing destructive latch-up during transient overvoltage events. |
Applications
| Power Sequencing Control | Industrial Sensor Interface |
|---|---|
Use Scenario: Coordinating startup order of multiple DC-DC converters in an FPGA-based motor controller. IC Role / Device Role / Timing Role: NAND gate implements AND-NOT logic to generate delayed enable signals based on voltage-good flags from upstream regulators. Use Value: Eliminates need for discrete transistors or dedicated sequencer ICs; reduces BOM count and PCB area while maintaining deterministic timing margins. | Use Scenario: Conditioning quadrature encoder signals before feeding into a microcontroller's timer capture unit. IC Role / Device Role / Timing Role: Debounces and inverts encoder channel edges to produce clean, synchronized direction pulses. Use Value: Leverages TTL input compatibility to accept open-collector encoder outputs directly; avoids signal inversion errors caused by mismatched logic families. |
| Microcontroller GPIO Expansion | Legacy Bus Glue Logic |
Use Scenario: Extending limited GPIO count on an ARM Cortex-M0+ MCU to drive eight discrete LED indicators. IC Role / Device Role / Timing Role: Combines pairs of MCU outputs to generate active-low enable signals for LED driver ICs. Use Value: Provides predictable 29 ns max propagation delay-well within timing budget for static indicator control-without introducing clock-domain uncertainty. | Use Scenario: Adapting a 5 V parallel data bus from an older microprocessor to a modern 3.3 V FPGA I/O bank. IC Role / Device Role / Timing Role: Implements NAND-based address decoding and chip-select arbitration logic between mixed-voltage domains. Use Value: TTL input thresholds ensure correct interpretation of 5 V bus signals; CMOS outputs safely interface to 3.3 V FPGA inputs via series 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 |
|---|---|---|---|
| SN74LVC2G00DBVR | Lower VCC range (1.65–5.5 V), higher speed (tpd = 3.2 ns typ @ 3.3 V), but only rated to +85 °C. | Not suitable for under-hood automotive or extended-temperature industrial use where +125 °C operation is mandatory. | Select when system operates at 3.3 V and thermal environment is benign; avoid where full automotive temp grade is required. |
| 74AHC2G00DP,125 | CMOS input thresholds (VIH = 3.15 V min @ VCC = 4.5 V), wider VCC range (2.0–5.5 V), identical TSSOP8 package and +125 °C rating. | Requires level translation when interfacing with true TTL outputs; unsuitable for direct replacement in legacy 5 V TTL systems. | Choose only if all driving sources are CMOS-compatible; verify input voltage compatibility before substitution. |
Compared with SN74LVC2G00DBVR and 74AHC2G00DP,125, the 74HCT2G00DP,125 uniquely delivers TTL-level input compatibility *and* full -40 °C to +125 °C qualification in the same compact TSSOP8 footprint-making it the sole option for upgrading legacy 5 V control logic in thermally demanding environments without redesigning input interfaces.

FAQ
What is the maximum recommended operating supply voltage for 74HCT2G00DP,125?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V per JEDEC JESD8C. Operation outside this window invalidates input threshold guarantees and may cause excessive ICC or reduced noise margin. The device is not characterized for reliable function at 6.0 V or above in HCT mode.
Can 74HCT2G00DP,125 drive a 50 pF capacitive load at 10 MHz?
Yes-it sustains 19 ns typical transition time (tt) into 50 pF at VCC = 4.5 V, resulting in < 5% duty-cycle distortion at 10 MHz. However, dynamic power dissipation rises to ~1.1 mW (PD = CPD × VCC² × fi × N), requiring adequate PCB thermal relief under continuous toggling.
Does 74HCT2G00DP,125 support hot insertion or live swapping?
No-this device lacks Ioff (power-off protection) or IOZ (three-state) functionality. Applying input signals while VCC is unpowered risks forward-biasing internal clamp diodes, potentially causing latch-up or excessive current draw. Power sequencing must ensure VCC is stable before asserting any inputs.
How does the input clamping diode affect external resistor selection?
When interfacing to voltages > VCC (e.g., 12 V sensor outputs), a series current-limiting resistor must restrict IIK to ≤ ±20 mA. For a 12 V source and VCC = 5 V, minimum R = (12 V − 5.5 V) / 20 mA = 325 Ω; 470 Ω is recommended to provide margin against transients and temperature drift.
