Product details

The SN74LVC1G06DCKJ: The open-drain output allows wired-OR connections and level translation without external pull-up conflicts. The SC-70-5 package fits tight board layouts.

This part is officially obsolete per the manufacturer's lifecycle status. That means TI no longer produces it, and no last-time-buy window is open. For a production BOM, you need a drop-in replacement or a redesign.

Supply voltage and level-shifting capability

Because the output is open drain, the pull-up voltage can be different from VCC — a common trick for level shifting: run VCC at the input-side voltage and pull up the output to the target logic level. The 32 mA sink capability handles typical bus loads and LED drive. Just remember the output only sinks current; it cannot source, so a pull-up resistor is mandatory.

Frequently asked questions

Is SN74LVC1G06DCKJ obsolete?

Yes, the SN74LVC1G06DCKJ is obsolete per the manufacturer's lifecycle status. TI has discontinued production, and no last-time-buy window is currently active. For new designs or replacement needs, a current-production pin-compatible alternative from the 74LVC family in the same SC-70-5 package is recommended.

What is the replacement for SN74LVC1G06DCKJ?

The manufacturer has not listed a direct successor for this order code. However, the 74LVC family includes several active single inverting buffers with open-drain output in SC-70-5. Check the current TI 74LVC1G06 variants that carry an active lifecycle status.

Can SN74LVC1G06DCKJ be used at 3.3V?

With an open-drain output, the pull-up voltage can be set to 3.3 V or any other voltage within the output's breakdown limit.
