Thanks hopefully a 1K should be fine i guess.I would advise not tying directly to a CMOS logic pin a large cap w/o limiting
discharge current thru internal protection diodes when supply collapses. This
can cause a die hot spot, even Si melting if current too high. Simply place a
series R at CMOS input to limit the discharge current. Some vendors spec injection
current, some not. In latter case a few mA should be ok.
