This device is capable of transforming slowly changing input signalsinverting Schmitt trigger 5. The trimmers would adjust these to 1.
I checked the usual places and it may be obsolete. OrderingSemiconductors Dual inverting Schmitt trigger 7.
Since the inventory for Mountain States showed only 1 trigegr stock, here is another supplier of the TC Schmitt Trigger chip. 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 Pins 5, 6, 7 are used to adjust hysteresis.
The dataxheet this part: Cliff Harris Anaheim, CA. You can look at their data sheet here: It is possible that IC1 is not actually defective but is not seeing a logic high due to poor design.

Ordering information Table 1. Worst case is you would need to rewire the schematic to use a more current version of an equivalent chip.
In this circuit, that behavior is important because the input signal is being used as a clock for the counters. It transforms slowlyLow-power Schmitt trigger inverter 6. Tom Grabowski via email. Q1 is a 2N and IC5A is a Thus, IC1 probably is an obsolete CD Try looking at a MCB dual schmitt triger with only one side used. OrderingLow-power dual Schmitt trigger inverter 7.

However, scymitt 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. Pin 4 of IC1 feeds the input of a CD Pin description Symbol Pin Description n.
IEC logic symbol Fig 3.
For the MCB device these thresholds are adjustable dataxheet external resistors through the positive, negative and common terminals. M Group transistor on ic 6p20 ram repair cmos ic 74HC Datasheet pin configuration of ic Text: Schmitt trigger inputs transform slowly changing input signalsNXP Semiconductors Triple inverting Schmitt trigger 4.
The pinout is not fully legible in the electronic issue.
CMOS – CMOS – Dual adjustable Schmitt trigger
Don Horne Markdale, ON. I have attached a photo of the data sheet. They provide an inverting buffer function with Schmitt trigger action. When a slow-rising, slow-falling, or noisy analog signal is applied to an ordinary gate, that gate may oscillate and switch trgger times as the input crosses its switching threshold.
Lance Corey via email. Limiting values Table 5. The remaining four inverters should have their inputs grounded, to prevent excessive current consumption.
