Product details

28 ns propagation delay — timing margin on a 5V bus

The maximum propagation delay is 28 ns at 4.5V supply with a 50 pF load.

Active lifecycle — no last-time-buy scramble

The CD74HCT20MT carries an Active product status and is ROHS3 compliant. For a BOM line that needs a dual 4-input NAND gate in a 14-SOIC footprint, this part is a safe choice for both new builds and repair stock — no LTB risk, no forced redesign to a different logic family.

Mounting and package — 14-SOIC, surface-mount only

The device comes in a 14-SOIC package with a body width of 3.90 mm (0.154"). It's a surface-mount part — no through-hole variant. The supplier device package is listed as 14-SOIC.

Frequently asked questions

What are the exact specifications of CD74HCT20MT?

It is a dual 4-input NAND gate from the 74HCT series. Supply voltage is 4.5V to 5.5V. Propagation delay is 28 ns max at 4.5V with 50 pF load. Output drive is 4 mA sink and source. Quiescent current is 2 µA max. Operating temperature range is -55°C to 125°C. Package is 14-SOIC (3.90 mm width) for surface mount.

Is CD74HCT20MT compatible with 5V logic?

Yes. The supply range of 4.5V to 5.5V and input thresholds of 0.8V (low) and 2V (high) are directly compatible with 5V TTL and CMOS logic families. No level shifting is needed.

What is the propagation delay of CD74HCT20MT?

This is the figure to use for worst-case timing analysis in your design.
