NXP Semiconductors 74LVC06AD,112

Overview

74LVC06AD,112 from Nexperia is a hex inverter IC with six independent open-drain outputs, designed for level translation between 3.3 V and 5 V logic domains. It operates across 1.2 V to 5.5 V supply, supports -40 °C to +125 °C ambient range, and enables wired-OR/AND bus interfacing in I²C, SMBus, and GPIO expansion circuits.

For engineers reviewing the 74LVC06AD,112 datasheet, 74LVC06AD,112 pinout, 74LVC06AD,112 application, or 74LVC06AD,112 equivalent, this device is selected for mixed-voltage signal conditioning, active-low bus arbitration, and bidirectional voltage-level shifting where low static current (<10 μA at 5.5 V), 5 V-tolerant inputs, and sub-3.5 ns propagation delay at 5 V are critical design requirements.

Technical Context

The 74LVC06AD implements six identical CMOS inverter stages, each with an open-drain output requiring external pull-up for HIGH assertion. Its input structure accepts voltages up to 5.5 V regardless of VCC, enabling robust interfacing between legacy 5 V peripherals and modern 1.8 V/2.5 V/3.3 V controllers.

Propagation delays are specified down to 1.5 ns (tPLZ/tPZL typ at VCC = 4.5–5.5 V), and dynamic power dissipation is governed by CPD = 7.2 pF (at 3.0–3.6 V), supporting high-speed digital control without excessive switching loss in compact embedded systems.

FAQ

Can 74LVC06AD,112 drive a 5 V pull-up while powered from 3.3 V?

Yes. Its 5 V-tolerant inputs and open-drain outputs allow the device to be powered from 3.3 V while sinking current from a 5 V pull-up resistor. Output LOW voltage remains ≤0.55 V at 32 mA load, ensuring clean logic LOW assertion on the 5 V bus.

Is a decoupling capacitor required for stable operation?

Yes. A minimum 100 nF ceramic capacitor must be placed between VCC (pin 14) and GND (pin 7), located within 5 mm of the package. This suppresses supply transients induced by simultaneous output switching, preventing false triggering or increased propagation delay variation.

What is the maximum sink current per output at 125 °C?

At Tamb = +125 °C and VCC = 4.5–5.5 V, the absolute maximum sink current per output is 24 mA, as limited by thermal derating of total power dissipation (500 mW max, derating linearly at 10.1 mW/K above 100 °C for SO14).

Does 74LVC06AD,112 support hot insertion?

No. The device lacks hot-swap protection circuitry. Applying VCC after signal inputs may cause latch-up or exceed input clamping current limits (-50 mA). Power sequencing must ensure VCC is stable before applying input signals.
