Product details

Single 8-input NAND gate in 14-SSOP

Package is 14-SSOP, 0.209-inch body width, 5.30 mm wide. Temperature range is -40°C to 125°C, so it's rated for industrial and automotive environments — engine bays, factory floor, outdoor telecom cabinets. Not just a benchtop part.

28 ns propagation delay — what it means for your timing budget

Maximum propagation delay is 28 ns at 4.5V supply and 50 pF load. Output drive is symmetric: 4 mA source and 4 mA sink. That's typical for HCT family gates. Enough to drive a few CMOS inputs or a single LED through a resistor, but not for heavy loads like relays or bus lines without a buffer. Quiescent current is just 2 µA max — negligible in battery-powered or always-on circuits. The gate draws almost nothing when not switching.

Lifecycle and compliance — active, no obsolescence worry

This part is marked as Active in the lifecycle status. No last-time-buy or end-of-life notice to plan around. For a BOM line, that means you can qualify it for new designs without worrying about a forced redesign in the next year or two. It's ROHS3 compliant, so it meets the latest European restrictions on hazardous substances. No lead, no cadmium, no phthalates. That's the standard for most commercial and industrial products today.

Frequently asked questions

What is the difference between 74HCT30DB,118 and 74HC30DB,118?

The key difference is the input threshold levels. The 74HCT version uses TTL-compatible thresholds (LOW below 0.8V, HIGH above 2V), while the 74HC version uses CMOS thresholds (LOW below about 1.5V, HIGH above about 3.5V at 5V supply). The 74HCT is the better choice if you are mixing with TTL logic; the 74HC is better for pure CMOS systems. Both are 8-input NAND gates in the same package.

What is the typical propagation delay of 74HCT30DB,118?

Typical delay will be lower, but the 28 ns figure is what you budget for in worst-case timing analysis.

Is 74HCT30DB,118 RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest EU restrictions on hazardous substances.
