No other tool is better, no matter the application, than the hammer. In every case, where I need a tool, I reach for the hammer. Loosen a bolt? Hammer. Cut wood? Hammer. Milling complex shapes out of metal? Hammer.

Now, about the best logic family: That depends on the application. Each has advantages and disadvantages and you must try to match those to what is important in each specific application.

But when the time comes to insert the IC into the socket? Be sure to use a hammer.' at: '' mazher_iqbal@rediffmail.com asks: " which logic family is best and why?" |Delete 'P-' before: '' but after: 'X9A3@Vnet.Net asks:

I have a 74HC02 at Vcc=3.1 V (battery powered switched via a Max6363)with an up level connected to a 74HC00 with Vcc=+5 (V standby in a PC) - The 74HC00 is not powered when the Vsb of the PC is off. The battery powered 74HC02 (in a latch arrangement) senses an event and sets to an up state. When Vsb comes on, the remainder of the circuits work fine. But when shutting the Vsb off, to run on the battery again, the 74HC00 pulls 8 ma or so out of the battery through the 74HC02. How can I interface these two circuits that are using different Vcc's to minimize the current drain?
