Hi
There is timing requirement for clock frequency of SN74HC595 and SN54HC595 as follows.
My customer want to have maximum specification at Vcc=3.3V for both SN54HC595 and SN74HC595 devices.
Do you have information you can share to the customer?
BestRegards
Hello,
It is fine to use linear interpolation on the given values in the datasheet to approximate your values for 3.3 V.
See this FAQ for more details on that.
regards,
Gabriel
Hi Gabriel
Thank you for your reply.
According to formula provided in FAQ link, I got following estimation.
54HC595 -> 10.96 MHz
74HC595 -> 12.8 MHz
