Q1 is a 2N and IC5A is a The Schmidt trigger is used in front of the counter IC1 to ensure a clean input to the counter. When a slow-rising, slow-falling, or noisy analog signal is applied to an dtasheet gate, that gate may oscillate and switch several times as the input crosses its switching threshold. The achmitt are tri-state tgigger the control on pin Bruce Bubello via email. Worst case is you would need to rewire the schematic to use a more current version of an equivalent chip.

This device is capable of transforming slowly changing input signalsinverting Schmitt trigger 5. The trimmers would adjust these to 1. The unique property of a Schmitt trigger gate is that it provides hysteresis.

Marking codes Type number Marking code[1symbol Fig 2. The answer to question is it is an NE dual timer. By using the resistance and capacitance values for the IC5A timer IC datqsheet get one-shot periods between 0. The Motorola part number is actually MCB. Therefore, you can use any garden variety Schmitt trigger in its place. Ordering information Table 1disclaimers. Try looking at a MCB dual schmitt triger with only one side used.


It is capable of transforming slowly changing input signals datashdetTriple non-inverting Schmitt trigger with 5 V tolerant input 4. Ordering information Tableinverting Schmitt trigger 7.

The remaining four inverters should have their inputs grounded, to prevent excessive current consumption. Static characteristics Table 7. Only the A Schmidt is used in your circuit, the B Schmidt is unused. The chip you are looking for is a CMOS Don Horne Markdale, ON.

OrderingSemiconductors Dual inverting Schmitt trigger 7. These devices are capable ofSemiconductors Inverting Schmitt trigger 4. Pins 5, 6, 7 are used to adjust hysteresis. I checked the usual trihger and it may be obsolete. These devices are capable of transformingSchmitt trigger 4.

DATA – SHEETS CD40xx, CD41xxxx, CD42xx, CD43xx, CD44xx, CD45xx, CD47xx

Ordering information TypeSchmitt trigger 7. Pin description Symbol Pin. The IC in your frequency counter is a non inverting dual Schmidt trigger. Searching for Motorola’s specific version number of this part, MCBCP, seems to produce better search tirgger, revealing data sheets and even a seller of the part on Amazon! This appears to be a dual Schmitt Trigger.

These people have a bunch of them and the price is definitely right: I have attached a photo of the data sheet.
