Part Number: SN74HCS595 Other Parts Discussed in Thread: SN74LV595A , Hi team,
Could you give me comment on following customer question? SN74HCS595 and SN74LV595A are candidates for their use case. They consider if those device can be used from serial to…
Part Number: SN74HCS595-Q1 Hi,
When startup, what are each outputs(QA~QH)?
My customer requires that outputs are low when startup, then do they need to reset by SRCLR?
Best Regards,

Part Number: SN74HC595 Other Parts Discussed in Thread: SN74HCS595
Hi team,
My customer used new RFAB SN74HC595 in their product but failed in doing conduction radiation. If replaced by an old batch device, it will pass the CS test. Test condition:…
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…
