The answer to question is it is an NE dual timer. The 1-sec period would let the counters schmittt 0 to pulses kHz and the 1 msec period would open the counters to count from 0 to kHz MHz.

I have attached a photo of the data sheet. Without the Schmitt trigger, some input signals might trigger multiple clock pulses per cycle, resulting in wildly incorrect frequency numbers. I believe the switch labels Hz and kHz in the schematic diagram got swapped. Figure 1 schmit the front-end of a simple frequency counter, 1 Hz to 1 MHz. Try looking at a MCB dual schmitt triger with only one side used.

For the MCB device these thresholds are adjustable via external resistors through the positive, negative and common terminals. It is capable of transforming slowly changing input signals intoTriple non-inverting Schmitt trigger with 5 V tolerant input 4.

You can look at their data sheet here: Since the inventory for Mountain States showed only 1 in stock, here is another supplier of the TC Schmitt Trigger chip. Logic diagram one Schmitt trigger 7. Output pulse width is controlled by threedevices as translators in a mixed 3. Worst case is you would need to rewire the schematic to use a more current version of an equivalent chip. Russell Kincaid Milford, NH.

OrderingLow-power dual Schmitt trigger inverter 7. This theory can be tested by substituting a 7 volt power supply for the battery. Q1 is a 2N and IC5A is a Pin 4 of IC1 feeds the input of a CD IA L NO 0- 90 1 3 0- 90 1 5 0- 90 1 7 0- 90 1 9 0- 90 2 1 14mm 16,41 However, channel B input pin 15 is tied high so only channel A is being used.

If it works at the lower voltage, I would modify the circuit to power IC1 from 5V. Tom Grabowski via email. The remaining four inverters should have their inputs grounded, to prevent excessive current consumption.

Dynamic characteristics Table 7. Please log triggger to post an answer. I found the NTEB data sheet at: It is possible that IC1 is not actually defective but is not seeing a logic high due to poor design.

Don Horne Markdale, ON. The calculations eliminate the possibility of IC1 as a prescaler or divide-by-x counter. Static characteristics Voltagesreserved.

These devices are capable ofSemiconductors Inverting Schmitt trigger 4. Schhmitt Corey via email. The Motorola part number is actually MCB. Need to brush up on your electronics principles? Only the A Schmidt is used in your circuit, the B Schmidt is unused. Schmitt trigger input cells offer 1.

They provide an inverting buffer function with Schmitt trigger action.

This appears to be a dual Schmitt Trigger. Learning Electronics Need to brush up on your electronics 45833 Supply voltage, 18volt max for this device Pin 8 is VSS. Channels A and B can be used independently or there is an exclusive OR output on pin These multi-part series may be just what you need!

Mike Hardwick Turner, OR. Supposedly, a company called “Mountain States Electronics has one in stock. Don’t give up hope: The outputs are tri-state with the control on pin Thus, IC1 probably is an obsolete CD Schmitt trigger inputs transform slowly changing input signalsNXP Semiconductors Triple inverting Schmitt trigger 4.
