I am thinking of connecting a 74259 (8-bit addressable latch) to a USBMOD4 device to ultimately control 8 mosfets. The data sheet for the latch said that you should hold pin G high while changing address lines to avoid mangling your stored values, and I'm trying to come up with an elegant solution.
My device sets all 8 data lines "simultaneously"; I need to ensure that the line connected to the enable doesn't drop until the address/data lines are set up.
I was thinking of a simple RC circuit sent into an schmitt inverter to delay the dropping of G for ~100ms...would this work reliably? Are there better ways of doing this?
