Nexperia USA Inc. 74LVC08ABQ-Q100,11

Overview

74LVC08ABQ-Q100 from Nexperia is an automotive-qualified quad 2-input AND gate in DHVQFN14 package, operating from 1.2 V to 3.6 V supply with 5 V-tolerant inputs. It delivers propagation delay as low as 1.0 ns at 3.0–3.6 V and supports mixed-voltage logic translation between 3.3 V and 5 V systems in engine control units and ADAS domain controllers.

For engineers reviewing the 74LVC08ABQ-Q100 datasheet, 74LVC08ABQ-Q100 pinout, 74LVC08ABQ-Q100 application, or 74LVC08ABQ-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, -40 °C to +125 °C operation, 5 V input tolerance, DHVQFN14 thermal-enhanced packaging, and sub-5 ns propagation delay across full voltage range.

Technical Context

This device implements four independent CMOS-based AND gates with rail-to-rail input voltage capability up to 5.5 V while powered from as low as 1.2 V. Its logic function conforms to IEC 60617-12 and JEDEC JESD8 standards for LVC-family level-shifting behavior.

Each gate exhibits matched propagation delays (tpd ≤ 4.8 ns max at VCC = 3.0–3.6 V) and output skew ≤ 1.5 ns, enabling synchronous signal conditioning in timing-critical automotive subsystems such as CAN/LIN interface logic and sensor fusion pre-processing stages.

FAQ

Is the 74LVC08ABQ-Q100 pin-compatible with standard 74LVC08A variants?

Yes-the DHVQFN14 pinout matches the functional assignment of all 14 terminals across SO14 (SOT108-1) and TSSOP14 (SOT402-1) variants, including identical 1A–4Y input/output mapping and GND/VCC placement. Mechanical footprint differs, but logic-level connectivity remains consistent.

What is the maximum recommended IO load capacitance for stable operation?

The datasheet specifies 50 pF maximum load capacitance for VCC = 3.0–3.6 V operation with ≤2.5 ns input rise/fall times. Exceeding 50 pF increases propagation delay nonlinearly and may cause marginal timing in high-speed paths; layout parasitics must be included in total CL calculation.

Does the exposed thermal pad (Pin 1 index area) require grounding?

No-the thermal pad has no electrical function per datasheet note: "This is not a ground pin. There is no electrical or mechanical requirement to solder the pad." If soldered, it must remain electrically floating or connect solely to GND plane to avoid noise coupling into sensitive analog sections.

How does the 5 V input tolerance behave at minimum supply voltage (1.2 V)?

Input clamp diodes remain active down to VCC = 1.2 V, allowing 0–5.5 V input signals without damage. However, VIH/VIL thresholds scale with VCC; at 1.2 V supply, VIH is 1.08 V min, so 5 V inputs are interpreted as HIGH but require external series resistors if driving high-current sources to limit IIK to <50 mA.
