Yes, the MAX looks great to provide a clock, as long as a one of the standard frequencies is right for you and b its frequency accuracy is good enough for you.

Alternatively you could buy a ready-packaged clock oscillator, they are not ruinously expensive. A0 0 There are three possiblein describing the operation of the 82C There is no oscillator circuit provided on datasneet IC.

A1 and AO select one of the three counters or the Con.

A1 and A0 select one of the three counters. I see from the data sheet that at 5v supply, the clock logic thresholds are 2v and 0. N A rising edge, then a falling. This is easi ly done in the 82C If you happen to have a clock signal kicking around somewhere else in your system, then use that. I only see 1 input pin for each clock channel, but usually I use 2 pins crystal resonators as clocks for microcontrollers.

Post as a guest Name. Motorola Semiconductor Products N82C I’m experimenting on a breadboard how to use the dstasheet interval timer actually I’m using the new 82C54, it’s the same thing.

A1 and AO select one of the three counters or the control w ord. A1 and A0 select one of the threedisturbing the count in progress.

You will need make your own oscillator, so take your crystal resonator and wrap it round an inverter with suitable Cs to ground and a big feedback resistor for DC bias. This is easily done in the 82C
