Using a Schmidt trigger in this application makes sense. So this would appear to be a Schmitt Trigger used to clean up the input signal. It transforms slowlyLow-power Schmitt trigger inverter 6. More details0. However, channel B input pin 15 is tied high so only channel A is being used. Here is their address and contact info: IEC logic symbol Fig 3. M Group transistor on ic 6p20 ram repair cmos ic 74HC Datasheet pin configuration of ic Text: Russell Kincaid Milford, NH.
For the MCB device these thresholds are adjustable via external resistors through the ttrigger, negative and common terminals. Jon Titus Herriman, UT. This appears to be a dual Schmitt Trigger.
Ordering information Table 1disclaimers. When a slow-rising, slow-falling, or datassheet analog signal is applied to an ordinary gate, that gate may oscillate and switch several times as the input crosses its switching threshold. Schmitt trigger inputs transform slowly changing input signalsNXP Semiconductors Triple inverting Schmitt trigger 4. Pin 13 is not connected which is very, very bad practice.

Worst case is you would need to rewire the schematic to use a more current version of an equivalent chip. Static characteristics Table 7. Bruce Bubello via email.
Pin description Symbol Pin Description n. You trigher look at their data sheet here: Kevin Kaas via email. Schmitt trigger input cells offer 1. Since the inventory for Mountain States showed only 1 in stock, here is another supplier of the TC Schmitt Trigger chip. The Motorola part number is actually MCB.
The unique property of a Schmitt trigger gate is that it provides hysteresis. It is capable of transforming slowly changing input signals intoTriple non-inverting Schmitt trigger with datasheft V tolerant input 4. Learning Electronics Need to brush up on your electronics principles? These multi-part series may be just what you need! Therefore, you can use any garden variety Schmitt trigger in its place.

The Schmidt trigger is used in front of the counter IC1 to ensure a clean input to the counter. Lance Corey via email. Figure 1 is the front-end of a simple frequency counter, 1 Hz to 1 MHz. No abstract text available Text: Using that to refine the search, the part is a dual Schmitt trigger buffer. These people have a bunch of them and the price is definitely right: This theory can be tested by substituting a 7 volt power supply for the battery.
Cliff Harris Anaheim, CA. Marking codesSchmitt trigger 7.

I found two conflicting datasheets on this. Roger Baker Redmond, WA. The calculations eliminate the possibility of IC1 as a prescaler or divide-by-x counter.
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.
