Edge Triggered SR Latch

June 18, 2008

I never really used an edge triggered SR latch in any of my circuits before, but I dug this from my bag of circuit goodies and it is just too nice not to share (does it show that I am designing circuits for too long?)

The basic idea is to use two regular run-of-the-mill flip flops and combine them to a single “SR latch like” construction which is edge triggered.
The circuit is displayed below, and I just can’t help it – admiring a circuit with some sort of cross coupling…

And a corresponding timing diagram:
