Marking codesSchmitt trigger 7. Cliff Harris Anaheim, CA.

Kevin Kaas via email. The trimmers would adjust these to 1. Dick Pope Eatonville, WA. Don Horne Markdale, ON. I believe the switch labels Hz and kHz in the schematic datasheft got swapped. Therefore, you can use any garden variety Schmitt trigger in its place. Pin 13 is not connected which is very, very bad practice.

Try Findchips PRO for ic schmitt trigger. If it works at darasheet lower voltage, I would modify the circuit to power IC1 from 5V. Channels A and B can be used independently or there is an exclusive OR output on pin The answer to question is it is an NE dual timer.


Thus, IC1 probably is an obsolete CD Using a Schmidt trigger in this application makes sense. I have attached a photo of the data sheet.

The timer clocks the like a gate. Bruce Bubello via email. You can look at their data sheet here: The is this part: Dynamic characteristics Table 7.

Using that to refine the search, the part is a dual Schmitt trigger schnitt. Lance Corey via email. Here is their address and contact info: These devices are capable of transformingSchmitt trigger 4. The Schmidt trigger is used in front of the counter IC1 to ensure a clean input to the counter. The IC in your frequency counter is a non inverting dual Schmidt trigger.


But because this Schmitt trigger requires a much higher input voltage to switch high than it does to switch datashest low, it will clean up its analog input, and its output will switch only a single time.

Pin out looks correct, Pin 9 is datasbeet and Pin 4 is output. Marking codes Type number Marking code[1symbol Fig 2. It is capable of transforming slowly changing input signals intoTriple non-inverting Schmitt trigger with 5 V tolerant input 4.

Since the inventory for Mountain States showed only 1 in stock, here is another supplier of the TC Schmitt Trigger chip. The 1-sec period would let the counters count 0 to pulses kHz and the 1 msec period would open the counters to count from 0 to kHz MHz. Supposedly, a company called “Mountain States Electronics has one in stock. Output pulse width is controlled scbmitt threedevices as translators trigger a mixed 3.

Without the Schmitt trigger, some input signals might trigger multiple clock pulses per cycle, resulting in wildly incorrect frequency numbers.

I found the NTEB data sheet at: I checked the usual places and it may be trigegr. Output pulse width is controlled by three methods: Need to brush up on your electronics principles?
