D Flip Flop with Q/, 6 or 8 channel

Other Parts Discussed in Thread: SN74HCS74-Q1, SN54ALS576B, SN74HC4060-Q1

Hi Team,

I am looking for a 6 and/or 8 channel D Flip Flop that includes Q/. Do we have any parts like this in our portfolio? Also, are any of them auto qualified?

FYI, the parametric search does not allow you to filter the Flip Flops by whether or not they have the Q/ output.

Thanks,

Jared

D flip-flops with Q (either complementary outputs or inverting outputs) are 74x74, 74x175, 74x576, and 74x577.

Only 74x74 devices are auto qualified, and they have at most two channels (e.g., SN74HCS74-Q1). Military-rated 54x175 devices have four channels.
The SN54ALS576B has eight channels. (Do you also need the non-inverting outputs?)

Thank you for the insight! I need one that has Q and Q/, so it looks like the SN74HCS74-Q1 is the highest channel count for auto qualified. Do you know if there is a six or eight channel version (non-auto) that has Q and Q/?

Thanks,

Jared

There are few applications where complementary outputs would be needed, so none of the high-channel-count devices allocate pins for that.

What do you need them for?

I need them to be used as a frequency divider. I have to take a two hour timer and make it into a 1 week timer.

Sounds like a job for the SN74HC4060-Q1.
