Product details

The Texas Instruments SN74AC14DR is a hex inverter with Schmitt-trigger inputs from the 74AC series. Each of the six channels inverts a single input, and the Schmitt-trigger hysteresis cleans up slow or noisy edges. Supply range runs from 2 V to 6 V. Outputs source or sink 24 mA per channel.

Supply voltage and input thresholds

Rated for 2 V to 6 V supply. The low-level input threshold is 0.5 V to 1.1 V; the high-level threshold is 2.2 V to 3.9 V.

Output drive and propagation delay

Each output can source or sink 24 mA. The 10 ns propagation delay at 5 V and 50 pF load is typical for the 74AC family. Quiescent current maxes at 2 µA.

Frequently asked questions

Does SN74AC14DR come in tape and reel?

Yes, the SN74AC14DR is available in Tape & Reel (TR) and Cut Tape (CT) options.

What are the alternatives for SN74AC14DR?

The SN74HCU04PWT is a 74HCU-series hex inverter without Schmitt-trigger inputs, with lower output drive (5.2 mA) and a 14 ns propagation delay at 6 V. The SN74HCS04PWR is a 74HCS-series hex inverter with Schmitt-trigger inputs, 7.8 mA output drive, and a wider temperature range to 125°C. The SN74LVU04APWT is a 74LVU-series hex inverter without Schmitt-trigger inputs, 12 mA output drive, and a faster 7 ns propagation delay at 5 V. Choose based on whether you need Schmitt-trigger hysteresis, output drive, or temperature range.
