Part Number: CD74HC4094 Other Parts Discussed in Thread: SN74HCS595 Hi, we want to connect each CD74HC4094 with 10mt CAT6 cable cascade, what problems can we face with? Thanks.
Hello Clemens,
Thank you for pointing that out. My oversight - I intended to use the SN74HCS165 for rows and the SN74HCS595 for columns, effectively scanning each button individually. This approach has proven effective with regular tactile buttons. However…
Hi Bob,
You will send Qh' from the first shift register to the SER IN of the second shift register.
You can refer to this diagram from the HCS595 datasheet: https://www.ti.com/lit/gpn/sn74hcs595
It looks like this thread made it to logic, so I guess the LED guys didn't have anything to add.
My recommendation would be to use a '595 logic function -- each device can drive up to 8 outputs and they are dead easy to control and daisy-chain. All…
TI does not make general-purpose SPI expanders.
I²C and SPI are not compatible.
If you have only inputs or only outputs, then you can use shift registers (e.g., SN74HCS165, SN74HCS595); their serial interface is SPI compatible. Alternatively, use…
Why have you chosen this particular device? Do you really need a bipolar, military-grade device?
As far as I can see, the '673 is not really designed for cascading. You can share all inputs, except for /CS, to address them separately.
If you have…
There are several alternate parts (SN74AHC595, SN74AHCT595, SN74HCS595, SN74HC595, SN74HCT595, CD74HC595), but all of them have outputs with lower drive strength.
Part Number: SN74HC595 Other Parts Discussed in Thread: SN74HCS595 , SN74AHC595 , SN74LV595A Hi team,
here we want to check the output drive current in 3.3V supply.
there is only have data for 5V supply as below.
i also see it will decrease in low voltage…
