Product details

Six open-collector inverters in a 14-SOIC footprint

The SN74ALS05AD: Six independent inverter gates with open-collector outputs in a 14-SOIC package. Each gate takes a single input.

Commercial temperature range — indoor use only

Rated 0°C to 70°C, this is a commercial-grade part.

Sourcing and lifecycle

TI lists the SN74ALS05AD as Active and ROHS3 compliant. For a BOM that needs a second-source hedge, the open-collector inverter function is common across the 74ALS family, but pin-for-pin replacement should be qualified against the specific pull-up and load conditions of your design.

Frequently asked questions

What is the propagation delay of SN74ALS05AD?

The maximum propagation delay is 54 ns at 5V supply with a 50 pF load. That is the worst-case figure from the input crossing 2V to the output falling through 0.8V.

Is SN74ALS05AD available in tube packaging?

Yes, the SN74ALS05AD is listed with a Tube package option. The device ships in a 14-SOIC surface-mount package.

What are the alternatives to SN74ALS05AD?

A functional alternative within the 74ALS family is the SN74ALS11ANS, which is a triple 3-input AND gate — different logic function, same open-collector output structure. For a hex inverter with Schmitt-trigger inputs and wider temperature range, the SN74HCS04PWR covers -40°C to 125°C but uses a totem-pole output, not open-collector. The SN74F00DR is a quad 2-input NAND gate in the 74F family with 5 ns propagation delay, but again totem-pole output. None is a drop-in replacement; verify the output structure and pinout against your board.

Can SN74ALS05AD be used as a buffer?

An inverter with open-collector output can be used as a buffer if you add an external pull-up resistor and accept the signal inversion — two inverters in series restore the polarity. But the intended use is wired-OR, level translation, or driving loads that require an open drain.

Is SN74ALS05AD RoHS compliant?

Yes, the SN74ALS05AD is ROHS3 compliant.

What is the difference between SN74ALS05A and SN74ALS05AD?

The 'D' suffix typically denotes the 14-SOIC package variant. The SN74ALS05AD is the surface-mount 14-SOIC version; the base SN74ALS05A without the D suffix is the through-hole DIP package. Electrical specifications are identical between the two.
