If you really must use the 74HC I would suggest: Email Required, but never shown.
74HC 3-to-8 Line Decoder/Demultiplexer
Country of origin United States US. 74nc138n is Low-powered shottky. The only time it would make sense would be if you were wanting to connect with 5 or more devices, in which case you would get a saving in the number of pins used.
Using multiple instances of the BME class associated with each selected output will allow proper tracking of any internal state and data associated with the device connected to that output.
Or, and this is just throwing ideas out there, don’t use the 74HC and tell your “lecturer” that it’s a stupid idea to use 3 pins 4 including the chip select pin to control a pair of devices that need a total of 2 pins.
There is also the ‘ series of 4 line to 16 line decoders. Please contact our partner Intertek directly for a re-calibration of your device: Home Questions Tags Users 74bc138n.
Dtaasheet wemos connects it to ground for you. The reading and accuracy of the instruments may change over time.

I know it’s because CS pin cannot detect. Yes, logic outputs are best protected from current spikes caused by trying to try and drive a capacitance of more than a couple of hundred pF.
Request higher bulk rates. The project is really a 24×16 LED matrix.

See below for verbose log of uploading my sketch. Send to a friend. Log in to see your specific prices. This is my code: An error occurred the shopping list s could not dataasheet be loaded. Total Price NOK You can get these from the data sheet for the device.
Outputs go as they are now. But yes, specific LED driving buffer chips would be far better. Unless you have datasheer logic level requirements that are out of satasheet ordinary, then you don’t need to worry overmuch about them.

Can I return the calibrated item if I am not satisfied with the device itself?
All orders for calibrated items are non-cancellable and non-returnable. You don’t need to know those as such, only the knock-on effect.
