Product details
Overview
74AHC14BQ-Q100 from Nexperia is an automotive-grade hex inverting Schmitt trigger IC with CMOS-level inputs, 2.0 V to 5.5 V supply range, -40 °C to +125 °C operating temperature, and DHVQFN14 package. It provides noise-immune signal conditioning for digital interface circuits in engine control units, body electronics, and ADAS sensor interfaces.
For engineers reviewing the 74AHC14BQ-Q100 datasheet, 74AHC14BQ-Q100 pinout, 74AHC14BQ-Q100 application, or 74AHC14BQ-Q100 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.45 V min at VCC = 5.5 V), propagation delay (3.2 ns typ at VCC = 5.0 V, CL = 15 pF), overvoltage-tolerant inputs (5.5 V), AEC-Q100 Grade 1 qualification, and DHVQFN thermal performance.
Technical Context
This device implements six independent inverting Schmitt triggers with hysteresis-VT+ = 3.85 V and VT− = 1.65 V at VCC = 5.5 V-enabling robust noise rejection in noisy automotive environments. Input thresholds are supply-dependent and defined per IEC 60134, ensuring reliable switching across voltage transients.
Each channel delivers balanced tPLH/tPHL propagation delays (≤11.0 ns max at VCC = 5.5 V, CL = 50 pF) and supports mixed-voltage translation via overvoltage-tolerant inputs rated to 5.5 V regardless of VCC level. The DHVQFN14 package features side-wettable flanks for AOI-compatible solder joint inspection.
Key Specifications

|
Use Scenario: Squaring up degraded LVDS or analog video sync pulses from rear-view camera modules. IC Role / Device Role / Timing Role: Inverting Schmitt trigger restoring signal integrity and timing margins for video timing controllers. Use Value: Prevents frame drop or sync loss due to cable-induced jitter and ground bounce in long harness runs. |
Use Scenario: Distributing and cleaning a 27 MHz reference clock to multiple audio codec and display controller ICs. IC Role / Device Role / Timing Role: Hex inverter used as non-inverting buffer (via double inversion) with matched propagation delays. Use Value: Ensures <100 ps skew between buffered clocks, meeting setup/hold timing for multi-sink synchronous audio/video systems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverting Schmitt trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT14BQ-Q100 | TTL-compatible inputs (VIH = 2.0 V min), lower VT+ (1.9 V at VCC = 4.5 V); identical package and AEC-Q100 rating | Better suited for legacy 5 V TTL logic interfacing; reduced hysteresis lowers noise margin vs. AHC variant | Select when interfacing with older 5 V microcontrollers or discrete transistor logic where TTL thresholds are required |
| SN74LV14AQPWRQ1 | TI part with LV logic family; VCC range 2.0–5.5 V, but lower drive strength (±6 mA vs. ±25 mA), higher ICC (100 μA max) | Lower power consumption at cost of reduced fan-out and slower propagation (7.5 ns typ vs. 3.2 ns) | Prefer for ultra-low-power body electronics where fan-out ≤4 and speed <50 MHz suffice |
Compared with 74AHCT14BQ-Q100, the AHC version offers superior noise immunity and faster switching, while SN74LV14AQPWRQ1 trades speed and drive for lower static current-making each optimal for distinct automotive subsystem constraints.

FAQ
Is the 74AHC14BQ-Q100 pin-compatible with the 74AHCT14BQ-Q100?
Yes-both share identical DHVQFN14 (SOT762-1) pinout, terminal count, and physical footprint. The only functional difference is input threshold compatibility: AHC uses CMOS thresholds (VIH ≈ 0.7×VCC), while AHCT uses TTL thresholds (VIH = 2.0 V min). No PCB redesign is needed for substitution, but system-level logic level validation is required.
Can the exposed thermal pad on the DHVQFN14 package be connected to ground?
Yes-the exposed pad (terminal 1 index area) has no electrical function but may be soldered to a GND copper pour to improve thermal dissipation. If connected, it must remain at GND potential; floating or unconnected is also acceptable per datasheet guidance. Thermal resistance drops by ~15 °C/W when thermally anchored.
What is the maximum capacitive load this device can drive reliably?
The 74AHC14BQ-Q100 is characterized up to 50 pF load capacitance with guaranteed timing (tpd ≤13.5 ns max at VCC = 5.5 V). Driving >50 pF risks increased propagation delay, reduced edge rate, and potential output stage overheating-external buffering is recommended for loads exceeding 60 pF or trace lengths >10 cm.
Does this device support hot insertion or live insertion into a powered backplane?
No-74AHC14BQ-Q100 lacks hot-swap protection circuitry. Its inputs are overvoltage-tolerant but not bus-holder or powered-off isolation enabled. Applying signals before VCC ramp-up may cause latch-up or excessive ICC. Power sequencing-VCC first, then inputs-is mandatory per datasheet absolute maximum ratings.
