Product details
Overview
74AHCT2G08DC,125 from Nexperia is a dual 2-input AND gate logic IC with TTL-compatible input thresholds, operating from 4.5 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V, propagation delay as low as 3.6 ns (typical at VCC = 5.0 V, CL = 15 pF), and specified for -40 °C to +125 °C ambient operation - used in level translation and signal gating within industrial control I/O modules.
For engineers reviewing the 74AHCT2G08DC,125 datasheet, 74AHCT2G08DC,125 pinout, 74AHCT2G08DC,125 application, or 74AHCT2G08DC,125 equivalent, this device serves as a robust, temperature-hardened dual AND gate for mixed-voltage interface bridging where TTL-level compatibility and sub-10 ns timing are required.
Technical Context
This device implements two independent AND logic functions in a single VSSOP8 package, with inputs tolerant to 5.5 V regardless of VCC, enabling safe interfacing between 3.3 V and 5 V domains. Its TTL-compatible VIH (2.0 V min) and VIL (0.8 V max) thresholds ensure reliable recognition of legacy 5 V logic signals.
Propagation delays are tightly balanced across both gates (tpd ≤ 8.0 ns max at -40 °C to +125 °C, CL = 15 pF), and output drive capability supports ±8 mA at VOH/VOL, maintaining rail-to-rail logic swing under load while sustaining CMOS-level static power efficiency (ICC ≤ 40 μA max at VCC = 5.5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input AND gate - provides two independent Boolean AND operations per package. |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V systems and tolerance against supply ripple. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees TTL-level recognition without external level shifters. |
| Propagation Delay | 3.6 ns (typ), 8.0 ns (max) at VCC = 5.0 V, CL = 15 pF - enables use in high-speed digital control paths. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, motor drive, and industrial PLC environments. |
| Output Drive | ±8 mA - sufficient to directly drive multiple 74-series inputs or small capacitive loads (≤50 pF). |
| Input Overvoltage Tolerance | Up to 5.5 V - allows safe connection to 5 V buses even when powered from lower VCC (e.g., 3.3 V not applicable here; device requires 4.5–5.5 V). |
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 | 1A | First AND gate input A - accepts TTL-level signals; overvoltage tolerant to 5.5 V. |
| 2 | 1B | First AND gate input B - electrically identical to 1A; enables dual-input logic evaluation. |
| 3 | 1Y | First AND gate output Y - drives downstream logic with CMOS-compatible voltage levels. |
| 4 | GND | Ground reference - must be connected to system 0 V plane for noise immunity and correct logic thresholds. |
| 5 | 2A | Second AND gate input A - independent of first gate; supports parallel logic path implementation. |
| 6 | 2B | Second AND gate input B - matches 1B functionality; enables compact dual-gate logic design. |
| 7 | 2Y | Second AND gate output Y - isolated output node; avoids loading effects on 1Y. |
| 8 | VCC | Positive supply - must be 4.5–5.5 V; powers both gates and defines output logic high level. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5–5.5 V - eliminates need for external translators when interfacing with legacy 5 V microcontrollers. |
| Overvoltage-tolerant inputs | Withstands up to 5.5 V regardless of VCC - protects against bus contention and hot-swap transients in mixed-voltage backplanes. |
| Balanced propagation delays | tpLH and tpHL matched within 0.3 ns (typ) - ensures deterministic timing in synchronous enable/gating applications. |
| High noise immunity | Typical noise margin > 1.2 V at VCC = 5.0 V - suppresses false triggering from EMI in industrial motor control enclosures. |
| Low static power consumption | ICC ≤ 40 μA max at VCC = 5.5 V, full temperature range - reduces thermal load in densely packed I/O modules. |
Applications
| Industrial PLC Input Conditioning | Legacy Microcontroller Bus Gating |
|---|---|
|
Use Scenario: Isolating and validating discrete sensor inputs (e.g., limit switches, proximity sensors) before feeding into a 5 V PLC CPU. IC Role / Device Role / Timing Role: Dual AND gate acts as hardware-enable filter - both inputs must assert true (sensor active + enable strobe) to pass signal; propagation delay <8 ns ensures cycle-accurate response. Use Value: Prevents spurious triggers from contact bounce or EMI by requiring coincident valid inputs, with no software overhead or MCU resource usage. |
Use Scenario: Enabling data transfer between a 5 V legacy MCU and peripheral devices only during valid address windows. IC Role / Device Role / Timing Role: One gate combines /CS and /RD signals to generate a synchronized /OE pulse; second gate validates /WR and address bits for write enable. Use Value: Enables precise hardware-based bus arbitration without adding wait states or consuming GPIO pins on aging microcontrollers. |
| Motor Driver Enable Sequencing | Power Supply Interlock Logic |
|
Use Scenario: Validating dual safety conditions (e.g., thermal OK + fault clear) before enabling H-bridge gate drivers in BLDC inverters. IC Role / Device Role / Timing Role: Each AND gate monitors one safety pair; outputs feed OR logic or direct enable lines to driver ICs. Use Value: Provides fail-safe hardware interlock with <10 ns decision latency - faster than firmware polling and immune to software lockup. |
Use Scenario: Ensuring redundant power rails (e.g., main + backup 5 V) are both stable before releasing reset to downstream logic. IC Role / Device Role / Timing Role: Gates combine PWR_OK signals from two regulators; output controls reset release via RC network or dedicated reset IC. Use Value: Eliminates risk of partial power-up states that cause latch-up or metastability in FPGAs and microprocessors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G08DCUR | CMOS input thresholds (VIH = 0.7×VCC), 1.65–5.5 V supply - lacks TTL compatibility; lower ICC (10 μA max). | Requires level-shifting for legacy 5 V TTL sources; better suited for battery-powered 3.3 V systems. | Select when interfacing modern low-voltage MCUs and power efficiency outweighs TTL compatibility. |
| 74AHC2G08DC,125 | CMOS input thresholds (VIH = 3.85 V min at VCC = 5.5 V), same package/temp range - no TTL-level recognition. | Cannot directly accept 5 V TTL outputs without external pull-ups or translators. | Choose only when all upstream logic is CMOS-compliant and overvoltage tolerance remains critical. |
Compared with SN74LVC2G08DCUR and 74AHC2G08DC,125, the 74AHCT2G08DC,125 uniquely delivers guaranteed TTL-level input compatibility at 5 V while retaining overvoltage tolerance and industrial temperature rating - making it the sole option for retrofitting legacy 5 V control systems without redesigning signal conditioning.

FAQ
Is 74AHCT2G08DC,125 pin-compatible with 74AHC2G08DC,125?
Yes - both share identical VSSOP8 (SOT765-1) pinout: pins 1/2/3/4/5/6/7/8 map to 1A/1B/1Y/GND/2A/2B/2Y/VCC respectively. However, input threshold behavior differs: 74AHCT2G08DC,125 accepts TTL levels (VIH ≥ 2.0 V), while 74AHC2G08DC,125 requires CMOS levels (VIH ≥ 3.85 V at VCC = 5.5 V), so direct substitution may cause logic errors if upstream sources are TTL.
What is the maximum capacitive load this device can drive reliably?
The 74AHCT2G08DC,125 is characterized up to 50 pF load capacitance, with propagation delay specified at CL = 15 pF and CL = 50 pF. At VCC = 5.0 V, tpd increases from 3.6 ns (typ) to 5.1 ns (typ) as CL rises from 15 pF to 50 pF. Driving >50 pF risks exceeding 10.5 ns max delay and increased ground bounce; add series termination or buffer stages for heavier loads.
Can this device operate at 3.3 V supply?
No - the 74AHCT2G08DC,125 is specified only for VCC = 4.5 V to 5.5 V per Table 6. At 3.3 V, VIH minimum (2.0 V) would exceed 60% of VCC, violating TTL input specification and risking unreliable HIGH detection; static characteristics (VOH, VOL) are also uncharacterized below 4.5 V, and operation is outside recommended conditions.
Does this part support hot-swap or live-insertion?
While inputs tolerate up to 5.5 V regardless of VCC, the device lacks explicit hot-swap protection features (e.g., power-on reset, slew-rate controlled outputs). Applying VCC after inputs are driven risks latch-up or undefined output states. For live-insertion, use external series resistors (≥100 Ω) on inputs and ensure VCC ramps before signal assertion - per JESD78 Class II Level A latch-up immunity (exceeds 100 mA).
