Nexperia USA Inc. 74LVC06ABQ,115

Overview

74LVC06ABQ,115 from Nexperia is a hex inverting buffer IC with six independent open-drain outputs, designed for level translation and wired-logic interfacing in mixed-voltage systems. It operates from 1.2 V to 5.5 V supply, accepts 5 V-tolerant inputs, and delivers ≤2.5 ns propagation delay at 5 V. Used in I²C bus pull-up coordination, GPIO signal inversion, and active-LOW wired-OR logic networks.

For engineers reviewing the 74LVC06ABQ,115 datasheet, 74LVC06ABQ,115 pinout, 74LVC06ABQ,115 application, or 74LVC06ABQ,115 equivalent, this device is selected for its dual-voltage interoperability (3.3 V ↔ 5 V), guaranteed -40 °C to +125 °C operation, low ICC (≤40 μA at 5.5 V), open-drain flexibility for bus sharing, and DHVQFN14 thermal performance.

Technical Context

This device implements six independent CMOS inverters with open-drain outputs-no internal pull-ups-requiring external resistors for HIGH-level assertion. Each gate follows strict truth table behavior: input LOW → output high-impedance (Z), input HIGH → output driven LOW.

Its 5 V-tolerant inputs enable direct connection to legacy 5 V TTL/CMOS logic while powered from 1.65–3.6 V rails, eliminating discrete level shifters. The DHVQFN14 package (SOT762-1) provides 14 terminals in a 2.5 × 3 mm footprint with exposed thermal pad for enhanced power dissipation up to 500 mW.

FAQ

Can 74LVC06ABQ,115 drive a 10 kΩ pull-up resistor on a 3.3 V I²C bus?

Yes. With VOL ≤ 0.55 V at 32 mA sink and typical IOZ leakage < ±10 μA, the device pulls the bus below 0.4 V when active, satisfying I²C LOW threshold (≤0.3×VDD = 0.99 V). At 10 kΩ, sink current is ~330 μA-well within its 32 mA rating and ensuring robust LOW-state margin.

Is the exposed thermal pad on the DHVQFN14 package electrically connected?

No. Per Figure 5 and datasheet note (1), the exposed pad is not electrically tied to any internal node. It may remain floating or be soldered to GND for thermal improvement-but if connected, must be isolated from VCC and signal traces to avoid short circuits.

What is the maximum clock frequency supported for toggling a single output?

While not a clocked device, its tPLZ/tPZL ≤ 3.5 ns at 5 V implies reliable operation up to ~140 MHz for repetitive square-wave inversion (1/(2×3.5 ns)), assuming proper load capacitance (≤50 pF) and PCB layout. Real-world bus speeds (e.g., I²C Fast Mode Plus at 1 MHz) are comfortably supported.

Does 74LVC06ABQ,115 require external pull-up resistors on all outputs?

Yes-absolutely. Open-drain outputs cannot source current; each 1Y–6Y must have an external pull-up resistor to VCC (or another rail) to define the HIGH state. Typical values range from 1 kΩ (for speed) to 10 kΩ (for power savings), depending on bus capacitance and rise-time requirements.
