It transforms slowlyLow-power Schmitt trigger inverter 6. Recommended operating conditions Table 5.

LimitingSingle Schmitt trigger buffer schmirt For the MCB device these thresholds are adjustable via external resistors through the positive, negative and common terminals. The answer to question is it is an NE dual timer. So this would appear to be a Schmitt Trigger used to clean up the input signal. Using that to refine the search, the part is a dual Schmitt trigger buffer. I have attached a photo of the data sheet.


Previous 1 2 Only the Trigger Schmidt is used in your circuit, the B Schmidt is unused. However, because the circuit does not actually take advantage of the unique programmable hysteresis feature of the by just tying pins 5, 6, and 7 togetherany other CMOS Schmitt trigger should work just as well, if you can find something cheaper and don’t mind slightly modifying the circuit.

This appears to be a dual Schmitt Trigger. Pin datasheeet Symbol Pin. Try Findchips PRO for ic schmitt trigger.

Kevin Kaas via email. However, channel B input pin 15 is tied high so only channel A is being used. The unique property of a Schmitt trigger gate is that it provides hysteresis. OrderingLow-power dual Schmitt trigger inverter 7.

I believe the switch labels Hz and kHz in the schematic diagram got swapped. Learning Electronics Need to brush up on your electronics principles? Dick Pope Eatonville, WA.

Russell Kincaid Milford, NH. Marking codes Type number Marking code[1symbol Fig 2. Ordering information Table 1disclaimers. I have attached a. Bruce Bubello via email.

Ordering information Tableinverting Schmitt trigger 7. If it works at the lower voltage, I would modify the circuit to power IC1 from 5V. Pin out looks correct, Pin 9 is input and Pin 4 is output.


It is possible that IC1 is not actually defective but is not seeing a logic high due to poor design. Don Horne Markdale, ON.

Try looking at a MCB dual schmitt triger with only one side used. Without the Schmitt trigger, some input signals might trigger multiple clock pulses per cycle, resulting in wildly incorrect frequency numbers. Marking codesSchmitt trigger 7. More details0. Here is their address and contact info: The Motorola part number is actually MCB. The logic high output from Q1 is only 5V.

The trimmers would adjust these to 1. These devices are capable of transformingSchmitt trigger 4. Mike Hardwick Turner, OR.
