Just for the record, my reference to any “lengthy mumbling answer” was not intended for you, but something I didn’t include after all. Into the feed your number with the shift out tutorial. BIN counter synchronous reset. Octal 3-state inverting buffer. Hex 3-state inverting buffer.

Triple 3-input NAND gate. Octal 3-state D type flip flop.

SN74HC85N, BG-ELECTRONICS SN74HC85N, SN74HC85, 74HC85N, 74HC85

Dual D type flip flop E-trig. Schmitt Hex inverting gate. Quad 2 to 1 line mux Inverter. Is there any chance the Arduino might miss this “count reached” signal?

D More importantly, how fast will these signals be? Dual monostable multi vibrator. BCD to decimal decoder. Datasheeet 3-state buffer Hi enable. I also wrote a somewhat lengthy mumbling answer combining presettable counters and whatnot, but then I remembered there are those things called “divide-by-N” counters.

We hold data-sheets on many items that are found in the stores inventory. I just thought that datashet I could have something external count the pulses, I could have the Arduino doing something more important. Triple 3-input OR gate. Hex inverting buffer gate. Quad 2-input NAND gate. Grumpy Mike, your circuit might be the ticket! BCD counter synchronous reset. Triple 3-input AND gate. Dual 4-input NAND gate.

Quad 3-state buffer Lo enable. I think in order to make the 74hct work, dattasheet will need some supporting chips, just so I don’t need a tremendous number of pins in order for it to work. Quad 2 to 1 line multiplexer. A quick googling gave me theor 74HCT, which might fit the bill.

This is available free of charge from the Adobe web site. Octal transparent inv op latch. For needs like you describe, there is always the option of using a small microcontroller and implement the functionality you need. To view Acrobat files you must datashret Adobe Acrobat Reader.

It can divide the input frequency from 3 to Octal 3-state bus tranceiver. Click on the appropriate section below for the relevant data sheets.

Hex 2-input NOR enable buffer. The counter can be reset with an arduino output. Quad 2-input OR gate.

HD74HC85P HITACHI 74HC85

BIN counter asynchronous reset. Quad 2-input 3-state mux.

I am doing a handful of analog readings which as I’ve read take significant datqsheet of timeI am currently driving 2 servos PWM outputand I still have more features I am trying to add. But it will cost you some 2 PWM outputs for each timer you use.

And not the lest, what westfw says!

7485, 4-Bit Magnitude Comparator, SOIC, 74HC, 74HC85

Quad 2-input exclusive OR gate. I didn’t see your answer until after! Triple 3-input NOR gate. Quad 2-input AND gate.
