Hey guys, welcome to this blog. Today is another comparison article on electronic components, we will focus on NE5532 and its similar components: OPA2134, TL072 and NE5534. So off we go!

NE5532 vs OPA2134

The NE5532 is a Bipolar Input op-amp and the OPA2134 is a Fet Input op-amp.

Although many people claim NE5532 as an old component and try to find a new one to take its place, the NE5532 is still good enough for most applications. Plenty of new audio equipment still uses old op-amps such as the NE5532 and TL072 because anything better is overkill and not cost-effective.

If you can use a bipolar OP, the NE5532 is usually the better choice than a JFET OPA2132 / OPA2134. The OPA2134 is more a better replacement for the TL072 when you need a FET type. This may be the case with low-frequency filters.

Hey guys, if you are an electronic DIY lover, you will always find a lot of similar or interchangeable components, which have subtle differences in the specs or features, therefore lead to the wrong application, 74HC595 and its similar components is an example I'm going to mention today.

74HC595 and 74HC164, 74LS595 and MCP23017, except for the last one, the former three ICs are shift registers that can drive LEDs, especially 74HC595, it can drive LEDs directly, those components are alike in some way and have their own distinguishing features as well.

So let's explore these four ICs specifications and compare them to see what are their differences.

74HC595 VS 74LS595

74LS595 is TTL based, fast, uses more power and is older.
74HC595 is CMOS based, fast, uses less power and is the most up-to-date version.
