Dual monostable multi vibrator.

BCD to decimal decoder. Octal transparent inv op latch. A quick googling gave me theor 74HCT, which might fit the bill. You can use a 74HC 8 bit counter feeding into one side of a 74HC85 magnitude comparatorthen feed the ddatasheet side from a shift register 74HC I have never used it, but judging from the datasheet it would seem so. But it will cost you some 2 PWM datazheet for each timer you use. Hex inverting buffer gate.

Octal 3-state D type flip flop. Octal 3-state bus tranceiver. Octal edge triggered latch. Quad 2-input AND gate. To view Acrobat files you must install Adobe Acrobat Reader. Quad 2-input exclusive OR gate. For needs like you describe, there is always the option of using a small microcontroller and implement the functionality you need. And not the lest, what westfw says! Triple 3-input NAND gate. Into the feed your number with the daatasheet out tutorial. Triple 3-input NOR gate. I also wrote a somewhat lengthy mumbling answer combining presettable counters and whatnot, but then I remembered there are datasheett things called “divide-by-N” counters.

Dual 2 to 4 line multiplexer. Quad 2 to 1 line multiplexer. I didn’t want to use the Arduino directly. Is there any chance the Arduino might miss this “count reached” signal? I am doing a handful of analog readings which as I’ve read take datasheeh amount of timeI am currently driving 2 servos PWM outputand I still have more features I am trying to add.

BCD counter synchronous reset. Click on the appropriate section below for the relevant data sheets. Schmitt Hex inverting gate. Logic Data sheets Series Component. Triple 3-input AND gate. Dual 4-bit binary counter.

I think in order to make the 74hct work, it will need some supporting chips, just so I don’t need a tremendous number of pins in order for it to work. Hex 3-state inverting buffer. Octal 3-state inverting buffer. I’m not sure how the hardware interrupt is made. Dual 4-input NAND gate. You all may be right, I may be trying to do something that the Arduino can already datassheet, but I just thought that if I could do it off board, I could save 74hd85 processing cycles for something more important.


Quad 2-input NAND gate. Just for the record, my reference to any “lengthy mumbling answer” was not intended for you, but something I didn’t include after all.

The counter can be reset with an arduino output. Dual 4-input NOR gate.

Hex 2-input NOR enable buffer. I just thought that if I could have something external count the pulses, I could have the Arduino doing something more important.

Quad 3-state buffer Lo enable. Quad 2 to 1 line mux Inverter.

It can divide the input frequency from 3 to BCD counter asynchronous reset.
