Product details

11 ns propagation delay — what it means for the bus

At 5V and 50 pF load, the max propagation delay is 11 ns per gate. Output low current is 8 mA.

Package and footprint

The 14-SOIC body is 3.90 mm wide. Pin 1 orientation is marked by a dot or notch on the package.

Temperature grade and environment

Rated for 0°C to 70°C — commercial temperature grade. That means it is at home in a desktop power supply, a printer logic board, or a lab instrument, but do not spec it for a motor drive cabinet or an outdoor telecom enclosure. The 74ALS family runs warm; at 5V and 70°C ambient, derate the output current if all six gates are switching simultaneously.

Field-service note

If you are carrying a field kit, the 14-SOIC package is small but manageable with tweezers and a standard iron. The 0°C to 70°C rating means it will not survive a hot truck dashboard in summer — keep spares in a cool part of the kit. Orientation: pin 1 is the end with the dot or notch; the datasheet has the pinout. No special ESD precautions beyond the usual wrist strap.

Frequently asked questions

What is the difference between SN74ALS04BDR and SN74ALS04D?

The SN74ALS04BDR and SN74ALS04D are electrically identical — same die, same 14-SOIC package. The only difference is the packing: BDR ships in Tape & Reel, while the D suffix typically comes in tubes or other bulk packaging. For a BOM, they are interchangeable; just match the packing to your pick-and-place feeder.

What is the cross reference for SN74ALS04BDR?

There is no official cross-reference listed for the SN74ALS04BDR. For a functional equivalent in a different logic family, the 74HCU04 or 74HCS04 series provide inversion with similar pinout but different supply voltage and temperature range — verify timing and drive before substituting.

What is the pinout of SN74ALS04BDR?

The SN74ALS04BDR follows the standard 74ALS04 pinout: six inverter gates, each with input and output pins, VCC on pin 14, GND on pin 7. The datasheet provides the full pin diagram.
