Lance Corey via email. The remaining four inverters should have their inputs grounded, to prevent excessive current consumption. When a slow-rising, slow-falling, or noisy analog signal is applied to an ordinary gate, that gate may oscillate and switch several times as the datqsheet crosses its switching threshold.

Ordering information Tableinverting Schmitt trigger 7. Figure 1 is the front-end of a simple frequency counter, 1 Hz to 1 MHz. Ordering information Table 1disclaimers.

The IC in your frequency counter is a non inverting dual Schmidt trigger. More details0. Ordering information TypeSchmitt trigger 7. This appears to be a dual Schmitt Trigger.

The trimmers would adjust these to 1. Worst case is you would need to rewire the schematic to use a more current version of an equivalent chip. This theory can be tested by substituting a 7 volt power supply for the battery. Dynamic characteristics Table 7. 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, dafasheet its output will switch only a single time.

Pin description Symbol Pin Description n. I have attached a. Pin 13 is not schnitt which is very, very bad practice. Tom Grabowski via email. The logic high output from Q1 is only 5V. Output pulse width is controlled by threedevices as translators in a mixed 3.

I believe the switch labels Hz and kHz in the schematic diagram got swapped. Bruce Bubello via email. Try looking at a MCB dual schmitt triger with only one side used. The pinout is not fully legible in the electronic issue.

I checked the usual places and it may be obsolete. The answer to question is it is an NE dual timer. Static characteristics Voltages triggre, reserved. Using that to refine the search, the grigger is a dual Schmitt trigger buffer. It is capable of transforming slowly changing input signals intoTriple non-inverting Schmitt trigger with scmhitt V tolerant input 4.

Also the logic high output voltage from IC1 is too high for the 5V downstream logic. These people have a bunch of them and the price is definitely right: Supply voltage, 18volt max for this device Pin 8 is VSS. Learning Electronics Need to brush up on your electronics principles? Without the Schmitt trigger, some input signals might trigger multiple clock pulses per cycle, resulting in wildly incorrect frequency numbers.

They provide an inverting buffer function with Schmitt trigger action. TOP Related Articles.
