These devices are capable ofSemiconductors Inverting Schmitt trigger 4. Here is their address and contact info: Bruce Bubello via email. The chip you are looking for is a CMOS Learning Electronics Need to brush up on your electronics principles? Recommended operating conditions Table 5. Only the A Schmidt is used in your circuit, the B Schmidt is unused. Searching for Motorola’s specific version number of this part, MCBCP, seems to produce better search results, revealing data sheets and even a seller of the part on Amazon!

Tom Grabowski via email. The pinout is not fully legible in the electronic issue. Try looking at a MCB dual schmitt triger with only one side used. Output pulse width is controlled by threedevices as translators in a mixed 3.


The logic high output from Q1 is only 5V. Pin description Symbol Pin Description n. The remaining four inverters should have their inputs grounded, to prevent datasgeet current consumption. The Motorola part number is actually MCB.

Supply voltage, 18volt max for this device Pin 8 is VSS. The outputs are tri-state with the control on pin It is possible that IC1 is not actually defective but is not seeing a logic high due to poor design.

Pin 4 of IC1 feeds the input of a CD These devices are capable of transformingSchmitt trigger 4. The Schmidt trigger is triggee in front of the counter IC1 to ensure a clean input to the counter.

The 1-sec period would let the counters schmitr 0 to pulses kHz and the 1 msec period would open the counters to count from 0 to kHz MHz. But because this Schmitt trigger requires a much higher input voltage to switch high than it does to switch back low, it will clean up its analog input, and its output will switch only a single time. Try Findchips PRO for ic schmitt trigger.

Lance Corey via email. It transforms slowlyLow-power Schmitt trigger inverter 6. The unique property of a Schmitt trigger gate is that it provides hysteresis.

Q1 is a 2N and IC5A is a Worst case is you would need to rewire the schematic to use a more current version of an equivalent chip. This appears to be a dual Schmitt Trigger. No abstract text available Text: Previous 1 2 Don’t give up hope: Ordering information Table 1.

Thus, IC1 probably is an obsolete CD They provide svhmitt inverting buffer function with Schmitt trigger action.
