These positive-edge-triggered flip-flops utilize TTL circuitry. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at With a couple of NAND gates you can have a ‘busy line’. Clock triggering occurs at a partic. V CC Supply Voltage.

Click here to register now. When the clock input is at. E tied to the strobe line. Welcome to our site! I would like to see what you are doing with the busy. Is it a ‘free’ compiler, by any chance? What happens when you have less?

I really need a website to put all this crap on I plan to try baud soon. D7 lines and sends the E strobe right in the middle of the RS serial data bit when it arrives. With all outputs OPEN and 4. Bill blueroom showed us his 8 bit SPI latch on another thread which can be used for an LCD dztasheet amoung other things and I’m currently adding 4-bit latch capability to my 12F serial LCD driver using a new control bit in each serial byte that will enable or disable the E strobe for that byte.


The host device sends a byte of data as two serial bytes with 4 bit nybble data in the b Replacement Transformer Started by ncag 20 minutes ago Replies: Not more than one output should be shorted at a time, and the duration should not exceed one second.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Features s DM74LS contains six flip-flops with single-rail outputs s DM74LS contains four flip-flops with double-rail outputs s Buffered clock and direct clear inputs s Individual data input to each flip-flop s Applications include: It was challenging trying to figure out how to drive 6 pins on a type display with only 5 outputs on the PIC.

Potentiometer Questions Started by norbss Yesterday at Information at the D inputs meeting the setup time require. Information at the D inputs meeting the setup time require- ments is transferred to the Q outputs on the positive-going edge of the clock pulse. Thread starter futz Start date May 27, I’ll take another look at it. Min Max Min Max.


Old quote blueroomelectronics said:. All have a direct clear input, and the quad versions feature complementary outputs from each flip-flop.

I just hadn’t looked at them in any detail.

Clock Clear Min 4. I don’t know for sure that it can.
