Product details
Overview
74AHCT2G08DP,125 from Nexperia is a dual 2-input AND gate logic IC in TSSOP8 package, operating from 4.5 V to 5.5 V supply, with TTL-compatible inputs, 8 ns typical propagation delay at 5 V/50 pF, and overvoltage-tolerant inputs up to 5.5 V-used for level translation and signal gating in mixed-voltage digital control subsystems.
For engineers reviewing the 74AHCT2G08DP,125 datasheet, 74AHCT2G08DP,125 pinout, 74AHCT2G08DP,125 application, or 74AHCT2G08DP,125 equivalent, this page delivers verified functional identity, validated pin mapping, confirmed static/dynamic specs across -40 °C to +125 °C, and real-world substitution guidance for industrial control and embedded interface design.
Technical Context
This device implements two independent AND gates with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and rail-to-rail CMOS outputs. Each gate exhibits symmetrical output impedance and balanced tPLH/tPHL propagation delays.
It supports mixed-voltage interfacing via overvoltage-tolerant inputs (up to 5.5 V regardless of VCC), enabling direct connection to 3.3 V logic driving 5 V systems or legacy TTL buses without external level shifters.
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 digital systems and tolerance against supply ripple. |
| Propagation Delay (tpd) | 3.6 ns (typ) to 8.0 ns (max) at VCC = 5 V, CL = 15 pF - enables reliable operation in sub-100 MHz synchronous logic paths. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - matches standard TTL voltage levels for seamless integration with legacy controllers and peripherals. |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads (<50 pF) without buffering. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and high-reliability embedded applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces risk of handling damage during PCB assembly and field service. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8-lead, 3 mm body width, 0.65 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First gate input A - accepts TTL-level signals; overvoltage tolerant to 5.5 V. |
| 2 | 1B | First gate input B - electrically identical to Pin 1; enables dual-input AND logic function. |
| 3 | 2Y | Second gate output Y - CMOS rail-to-rail output capable of sinking/sourcing ±8 mA. |
| 4 | GND | Ground reference - must be low-impedance connection to minimize switching noise coupling. |
| 5 | 2A | Second gate input A - independent of first gate; supports asynchronous logic routing. |
| 6 | 2B | Second gate input B - paired with Pin 5 to form second AND function. |
| 7 | 1Y | First gate output Y - matches Pin 3 electrical behavior; routed separately for fanout flexibility. |
| 8 | VCC | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Withstand up to 5.5 V regardless of VCC - eliminates need for external clamping diodes when interfacing 3.3 V microcontrollers to 5 V peripherals. |
| Wide temperature range | Specified from -40 °C to +125 °C - supports deployment in engine control units, motor drives, and outdoor industrial gateways. |
| Low dynamic power | CPD = 19 pF per buffer - limits switching current in high-frequency enable/control paths, reducing system-level heat generation. |
| Symmetrical output drive | Matched rise/fall times (tPLH ≈ tPHL) - minimizes duty cycle distortion in clocked enable signals and pulse-width modulated control lines. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V at 5 V - ensures reliable recognition of legacy 5 V TTL outputs without level-shifting circuitry. |
Applications
| Industrial PLC Digital Input Module | Automotive Body Control Unit (BCU) |

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, 3.7 ns tpd @ 3.3 V/50 pF | Better suited for 3.3 V-only systems; lacks TTL compatibility and 125 °C rating | Select when interfacing exclusively with modern low-voltage MCUs and board space is constrained (VSSOP8 same footprint). |
| 74AHC2G08DP,125 | CMOS input thresholds (VIH = 3.85 V min @ 5.5 V), identical package and temp range, 5.9 ns tpd @ 5 V/15 pF | Requires CMOS-level inputs; unsuitable for direct TTL bus interfacing | Choose where system uses only CMOS logic families and higher noise immunity is prioritized over TTL compatibility. |

FAQ
Is 74AHCT2G08DP,125 pin-compatible with 74AHC2G08DP,125?
Yes-both share identical TSSOP8 (SOT505-2) pinout, thermal profile, and mechanical dimensions. The only functional difference is input threshold voltage: 74AHCT2G08DP,125 accepts TTL levels (VIH ≥ 2.0 V), while 74AHC2G08DP,125 requires CMOS levels (VIH ≥ 3.85 V at 5.5 V). No PCB redesign is needed for substitution if input source logic family matches.
What is the maximum capacitive load this device can drive reliably?
The 74AHCT2G08DP,125 is characterized up to 50 pF load capacitance with guaranteed 8.0 ns max propagation delay at VCC = 5 V. Driving >50 pF risks increased delay, reduced noise margin, and potential output ringing; for heavier loads, add a series resistor (22–47 Ω) near the output or use a dedicated buffer stage.
Does this part support 3.3 V operation?
No-74AHCT2G08DP,125 is specified only for 4.5 V to 5.5 V supply. Its TTL input thresholds are optimized for 5 V systems; operation below 4.5 V violates recommended conditions and may cause unreliable VIH/VIL margins. For 3.3 V dual AND gates, consider SN74LVC2G08DCUR or 74AHC2G08DP,125 instead.
How does overvoltage tolerance work on the inputs?
Inputs tolerate up to 5.5 V regardless of VCC value due to internal clamp structures. This allows safe connection to 5 V buses while VCC is at 4.5 V, or to hot-plugged signals exceeding supply rail-without external protection. Current into the input is limited to ±20 mA per JESD78, preventing latch-up under transient overvoltage events.
