Product details
Overview
74AHCT1G08QW5-7 from Diodes Incorporated is an automotive-grade single 2-input positive AND gate in SOT25 package, operating from 4.5V to 5.5V with ±8mA output drive at 5.0V, balanced propagation delays (typ. 3.6ns @15pF), and AEC-Q100 Grade 1 qualification (-40°C to +125°C). It performs Boolean Y = A • B in push-pull logic circuits for signal gating in engine control units and body electronics.
For engineers reviewing the 74AHCT1G08QW5-7 datasheet, 74AHCT1G08QW5-7 pinout, 74AHCT1G08QW5-7 application, or 74AHCT1G08QW5-7 equivalent, this page delivers verified electrical specs, automotive thermal performance data, SOT25 terminal mapping, and direct substitution guidance for logic-level signal conditioning in IATF 16949 production environments.
Technical Context
This device implements a non-inverting 2-input AND function with Schmitt-trigger inputs-enabling robust operation with slow-rising signals-and standard CMOS push-pull outputs compatible with TTL-level inputs. Its input voltage range extends beyond VCC (–0.5V to 6.5V), supporting mixed-voltage interfacing.
Designed for automotive Grade 1 environments, it maintains guaranteed switching performance across –40°C to +125°C ambient, with propagation delay variation ≤2.4ns over temperature (1.0–8.0ns max) and output drive stability (VOH ≥3.70V @ –8mA, VOL ≤0.55V @ 8mA) under full supply and load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 2-input positive AND (Y = A • B); enables conditional signal pass-through in control sequencing |
| Supply Voltage Range | 4.5V to 5.5V; matches automotive 5V rail tolerances without external regulation |
| Output Drive | ±8mA @ 5.0V; sufficient to drive 10 LS-TTL loads or interface directly with microcontroller GPIO |
| Propagation Delay | 3.6ns typ. (CL = 15pF, VCC = 5V); supports >100MHz toggle rates in combinatorial paths |
| Operating Temperature | –40°C to +125°C ambient (Grade 1); qualified per AEC-Q100 for under-hood ECUs |
| Input Thresholds | VIL ≤ 0.8V, VIH ≥ 2.0V @ 5V; ensures noise margin >1.2V in noisy automotive environments |
| ESD Protection | 2kV HBM, 1kV CDM; exceeds AEC-Q100-002/-011 for assembly-line robustness |
Pinout & Package
SOT25 (3.0mm × 2.8mm × 1.2mm, 0.95mm lead pitch) surface-mount package with matte tin-plated leads, moisture sensitivity level 1, and IATF 16949-certified manufacturing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | First logic operand; Schmitt-triggered for immunity to slow edges and EMI-induced glitches |
| 2 (B) | Data Input | Second logic operand; electrically identical to Pin 1, enabling symmetric layout routing |
| 3 (GND) | Ground Reference | Return path for output current and internal bias; must be low-inductance connection to minimize ground bounce |
| 4 (Y) | Data Output | Push-pull CMOS output driving high/low actively; no external pull-up required for TTL compatibility |
| 5 (VCC) | Power Supply | Primary 4.5–5.5V supply; decoupling capacitor (100nF) required within 5mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable switching with rise/fall times up to 20 ns/V-critical for noisy sensor signal conditioning |
| Input voltage range beyond VCC | Supports –0.5V to 6.5V inputs, allowing safe interfacing with 3.3V controllers or overvoltage-tolerant sensors |
| Balanced propagation delays | Ensures <1ns skew between A→Y and B→Y paths-essential for glitch-free enable timing in synchronous systems |
| Low ICC supply current | Max 40μA at –40°C to +125°C; reduces quiescent power in always-on vehicle modules |
| AEC-Q100 qualification | Validated for Grade 1 operation, latch-up immunity (>100mA), and PPAP readiness-required for Tier 1 automotive BOMs |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
|
Use Scenario: Gating ignition coil enable signals based on crankshaft position and camshaft sync pulses. IC Role / Device Role / Timing Role: Combinatorial logic gate performing real-time AND of two safety-critical timing signals before power stage activation. Use Value: Prevents misfire by ensuring dual-sensor agreement; Schmitt inputs reject EMI from adjacent high-current solenoids. |
Use Scenario: Enabling door lock actuator drivers only when both key fob authentication and door handle switch are asserted. IC Role / Device Role / Timing Role: Safety interlock gate verifying concurrent user intent and system authorization prior to mechanical actuation. Use Value: Eliminates spurious lock/unlock events from RF interference or switch bounce-reducing warranty claims. |
| Advanced Driver Assistance System (ADAS) Camera Power Sequencing | Automotive Infotainment Display Backlight Control |
|
Use Scenario: Enabling camera sensor power only after image processor reset completion and voltage rail stabilization. IC Role / Device Role / Timing Role: Power-enable synchronizer ensuring strict sequencing between SoC and peripheral sensors. Use Value: Prevents camera initialization faults during cold start; 125°C rating supports under-dash mounting near HVAC ducts. |
Use Scenario: Activating LED backlight drivers only when display controller asserts valid video data and brightness command. IC Role / Device Role / Timing Role: Data-validity gate preventing backlight flicker or black-screen artifacts during GPU pipeline stalls. Use Value: Improves perceived UI responsiveness; ±8mA drive directly sources PWM dimming control lines without buffer ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AHCT1G08DBVR | Same logic function and 4.5–5.5V supply, but SOT-23-5 package (2.92mm × 1.6mm); 1.5ns faster tPD (typ. 2.1ns @15pF) | Higher board density possible; less thermal mass limits sustained 125°C operation in high-power clusters | Select for space-constrained PCBs where thermal derating is managed via layout, not ambient rating. |
| 74LVC1G08GW,125 | Wider supply range (1.65–5.5V), but only AEC-Q200 qualified (not Q100); lower drive (±4mA @3.3V) | Acceptable for infotainment peripherals but excluded from powertrain or ADAS due to missing Grade 1 validation | Choose for cost-sensitive cabin modules where full AEC-Q100 is not mandated by OEM spec. |
Compared with SN74AHCT1G08DBVR and 74LVC1G08GW,125, the 74AHCT1G08QW5-7 uniquely combines AEC-Q100 Grade 1 certification, SOT25's superior thermal resistance (θJA = 184°C/W vs. 220+°C/W for SOT-23), and guaranteed 125°C output drive-making it the only choice for under-hood logic gating where reliability trumps footprint.

FAQ
Can 74AHCT1G08QW5-7 operate with a 3.3V supply?
No. The device is specified only for 4.5V to 5.5V operation per its Recommended Operating Conditions. At 3.3V, input thresholds (VIH ≥2.0V) become unmet, and output drive collapses below specification-risking logic failures. Use 74LVC1G08 for 3.3V systems.
Is the SOT25 package RoHS and halogen-free?
Yes. The 74AHCT1G08QW5-7 is fully RoHS 3 compliant (2015/863/EU) with no intentionally added lead, and qualifies as "Green" per Diodes' definition: Br <900ppm, Cl <900ppm (Br+Cl <1500ppm), Sb <1000ppm-verified in manufacturing lot records.
What is the maximum capacitive load this AND gate can drive reliably?
The datasheet specifies performance up to 50pF (tPD ≤10.5ns max at –40°C to +125°C). Driving >50pF increases propagation delay nonlinearly and may cause marginal timing in high-speed paths; for >50pF loads, add a buffer stage or select a higher-drive logic family.
How does the Schmitt-trigger input improve system robustness?
Schmitt-trigger inputs provide hysteresis (typically 0.3–0.5V), eliminating multiple transitions on slow or noisy signals-such as those from mechanical switches or inductive sensors. This prevents false triggering in engine bay environments where EMI and voltage transients exceed standard CMOS input noise margins.
