Electronics Design – specialist subreddits Audio construction: As for the pins, the TI datasheet mentions they were designed as a pin compatible replacement.

Theory Datasheet confusion 74hcu04 self. But then, they weren’t designed to be used as analogue devices Solar Ask here if designing or repairing your own electronic control circuits. Electrical wiring home, industrial: You must categorize your question by clicking the ” add tag ” flair button after posting it. Construction, mods and powering: Construction Physically implementing a design e.

General electronics theory eg: You want the ‘Repair’ tag. We cover designing or repairing solar-related electronic circuits control and management systems. Meta Related to this datasheet. But then you are not using it for a typical application, so do whatever you want, it’s a cheap chip if you burn it up.

Extra rules apply to questions on vehicle electronics – please read before posting.

Use this tag if you need help sourcing electronic components or parts related to a circuit build or repair. One is less error prone than the other. Fixing a commercial product.


You wouldn’t “drag current out of it” in any typical application.

Still, if I avoid sitting it on that exact centre bias point it should be fairly happy, add a 10M pulldown or something and will be using probably 3. Home audio repairs especially for vintage gear: I mean Fig 13 in the datasheet is a Linear Amplifier, I actually bought these unbuffered devices because they are the recommended version for analog purposes from an app note I was looking at.

Yes, you are reading it correctly. By dragging current out of it, I was talking uA or mA btw, its not a power device, certainly not going to heatsink a 74hfu04 chip, thats cray cray: Questions on use, specifications, buyng spares and maintenance.

Yeh, i dont care about blowing it up, just getting a good handle on what I am dealing with before designing a rig for it. When I want to measure single digit DC micro amperes, I use one of these 0. Be sure to read Fairchild’s application note AN too. Household electrical wiring, connectors and fittings: Cause thats the maximum output current, surely adding a FB resistor to bias the device into this analog region is pushing the mosfets to the limit before you even start to drag some current out of it??

Not for general dagasheet my PC’ etc.

A few of these arrived today as I wanted to experiment with them as analog units. Yep, a better choice in hindsight, I was looking for a low voltage device though, probably off a lithium and the hcu04 should have a better transfer characteristic at v, also low current was the plan lol.


Can’t find it listed anywhere yet. For general setup questions, ‘how tos’, specifications and what-connects-to-what etc. Ask the mods before posting.

Theory General electronics theory eg: It’s a DC measurement and since the gate is unbuffered, there’s no possibility of oscillation.

Datassheet hookup and buying advice: Design Help with circuit design: Identifying an electronic component in an electronic assembly. Its a building block, it can be used analog if you want: I assume given the higher minimum Vcc they run a higher gate threshold voltage and less Id when Vgs is 0.

Electrical installation work and parts, home lighting inc. Lighting, audio, wiring, fixing etc. I’ve seen them used as final amps for super low power ham radio transmitters. To reiterate again, 74hhcu04 trust the datasheet is correct, I was not sure if I was misinterpreting it. Help with circuit design: Be sure to connect all other input pins to VSS. One of the datasheets has some transfer characteristics I am not sure I understand. If in doubt seek an expert.
