Product details
Overview
74AHCT08BQ-Q100 from Nexperia is an automotive-qualified quad 2-input AND gate in DHVQFN14 package, operating from -40 °C to +125 °C with TTL-compatible inputs (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 5.5 V overvoltage-tolerant inputs, and propagation delay of 3.2–9.0 ns (CL = 15–50 pF). It serves as a level-translating logic gate in automotive body control modules requiring mixed-voltage signal conditioning.
For engineers reviewing the 74AHCT08BQ-Q100 datasheet, 74AHCT08BQ-Q100 pinout, 74AHCT08BQ-Q100 application, or 74AHCT08BQ-Q100 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification, DHVQFN14 thermal-enhanced footprint with side-wettable flanks for AOI, TTL input thresholds, and guaranteed operation up to +125 °C ambient.
Technical Context
This device implements four independent 2-input AND gates with Schmitt-trigger action on all inputs, enabling noise-immune signal conditioning in electrically noisy automotive environments. Each gate exhibits balanced tPLH/tPHL propagation delays and supports rail-to-rail output swing (VOH ≥ 3.94 V, VOL ≤ 0.36 V at IO = ±8 mA, VCC = 4.5 V).
Input overvoltage tolerance to 5.5 V allows interfacing between 3.3 V logic domains and 5 V subsystems without external level shifters. The DHVQFN14 package (SOT762-1) features a thermally enhanced exposed pad and side-wettable flanks for automated optical inspection of solder joints - critical for high-reliability automotive PCB assembly.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT08PW-Q100 | TSSOP14 package (SOT402-1); same electrical specs but larger footprint and lower thermal performance | Suitable for prototyping or low-volume boards where AOI is not required and thermal density is lower | Select when manual rework or legacy TSSOP assembly lines are used; avoid for high-power-density automotive modules |
| SN74AHCT08QPWRQ1 | Texas Instruments part in TSSOP14; identical function and AEC-Q100 Grade 1, but different pinout and slightly higher ICC (max 40 μA vs 20 μA) | Drop-in replacement only with layout revision; requires validation of VIH/VIL margins in TI's characterization | Choose only if TI supply chain integration is mandated; verify noise immunity and propagation delay matching per application timing budget |
Compared with 74AHCT08PW-Q100 and SN74AHCT08QPWRQ1, the 74AHCT08BQ-Q100 offers superior thermal performance and automated optical inspectability via its DHVQFN14 package - critical for high-reliability, high-volume automotive production where solder joint integrity and junction temperature management are design-critical.

FAQ
Is the exposed thermal pad on the DHVQFN14 package electrically connected?
No - the exposed pad (Pin 1 index area) is not electrically connected to any internal node. Per Nexperia documentation, it may remain floating or be connected to GND for thermal enhancement, but no electrical requirement exists for soldering it. If soldered, the land must be isolated from other nets unless tied to GND.
Can 74AHCT08BQ-Q100 operate with a 3.3 V supply?
No - the 74AHCT08BQ-Q100 variant is specified only for 4.5 V to 5.5 V supply. Its TTL-compatible inputs require VIH ≥ 2.0 V, which is met at 5 V, but the recommended operating conditions explicitly exclude 3.3 V. For 3.3 V systems, use the 74AHC08BQ-Q100 variant instead.
What is the maximum output current per pin, and how is it defined?
The absolute maximum output current is ±25 mA per output pin (IO), per Table 4. However, the recommended operating condition specifies ±8.0 mA for VOH/VOL testing. Sustained operation above ±8 mA risks exceeding thermal limits and degrading VOL/VOH performance; continuous DC loading should stay within ±8 mA for guaranteed logic levels.
Does this device support hot-swap or live-insertion?
No - the 74AHCT08BQ-Q100 lacks explicit hot-swap protection features such as power-up sequencing control, Ioff, or bus-hold. Its overvoltage-tolerant inputs (to 5.5 V) provide limited transient resilience, but applying VCC after inputs or vice versa may cause latch-up or undefined states. Power sequencing must follow VCC-first, then inputs.
