Part Number: SN7404 Tool/software: Hello,
We have a test equipment application that requires operation down to -43degC. Is there a logic family that is specified to operate at or below this temperature?
Thank you.

I am looking for a voltage level conversion chip or buffer.
I need to convert my signal voltage from 3.3V to 15V.
SN7404D seems not…
Part Number: SN7404 Hello,
Often you will find the same component in both categories, but what about “normal” components with space heritage?
I am thinking about plastic packages with more than one BJT transistor (for instance opams and logic gates…
Hi Franz, The SN7404 is part of the very first logic family to ever be created -- way back in the 1960's. These devices do not have any extra features, including added ESD protection. There are many other options for hex inverters that are more modern…
Part Number: SN7404 On page 4 of the data sheet there are schematics for each gate in the chip. The LS04 and S04 schematics include a symbol that looks like a BJT transistor, but the "base" component has what looks like Zenner symbol attached.
Please…
Other Parts Discussed in Thread: SN7404 I'm assembling the SN7404 on a bread board. The instrument requires a supply voltage of 5 V and ground to operate. I have a 5 V dc power supply, therefore would i connect the negative from the power supply to the…

Part Number: SN7407 Other Parts Discussed in Thread: SN7404 , SN74LS07 , SN74LVC07A , Hello,
Im having an issue with the SN7404 IC. The image bellow shows how it is designed. The R7 Resistor Array is used to pull down the 7407 input, so when the CN7…
TTL was designed for 5 V only.
The internal organization of the SN7414 is not documented. But let's look at the SN7404:
When you change V CC , the currents through all the resistors will be different. For the SN7404, this means that the input currents…
