I have a customer who asks us to design and deliver timing gadgets, in a day or two, for free. He can't get anything done internally in any useful time. They're good guys and do good stuff, so we try to accommodate.
They have a Pockels cell electro-optic modulator and want to try a new high-voltage driver. They have an input pulse but need to turn on the pullup and pulldown mosfets separately. Takes two one-shots. But they want to work down to 5 ns input pulses, so I used the really cute SN74LVC1G123, which is basically an HC123 with screaming TinyLogic speed.
(have I mentioned lately how much I like that gold-plated copperclad?)
The nasty part was soldering those US8 chips. The Bellin MSOP8 adapters are 25 mm pitch, and the chips are 20, so I had to bend the pins out.
It's labor intensive, but satisfying, to build things like this.
