Schmitt trigger input cells offer 1. Russell Kincaid Milford, NH.

This theory can be tested by substituting a 7 volt power supply for the battery. 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 These devices are capable ofSemiconductors Inverting Schmitt trigger 4.


Please log in to post an answer. Without the Schmitt trigger, some input signals might trigger multiple clock pulses per cycle, resulting in wildly incorrect frequency numbers. Limiting values Table 5. Mike Hardwick Turner, OR. Functional diagram 1 3 5 9 11rights reserved.

NTEB Integrated Circuit CMOS − Dual Schmitt Trigger

Lance Corey via email. The Motorola part ratasheet is actually MCB. They provide an inverting buffer function with Schmitt trigger action. Channels A and B can be used independently or there is an exclusive OR output on pin No abstract text available Text: Worst case is you would need to rewire the schematic to use a more current version of an equivalent chip.


Dynamic characteristics Table 7. The remaining four inverters should have their inputs grounded, to prevent excessive current consumption. By using the resistance and capacitance values for the IC5A timer IC we get one-shot periods between 0.

Output pulse width is dataasheet by three methods: I have attached a photo of the data sheet. Pin 13 is not connected which is very, very bad practice.

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. Q1 is a 2N and IC5A is a These devices are capable of transformingSatasheet trigger 4.

Here is their address and contact info: Jon Titus Herriman, UT. The chip you are looking for is a CMOS More details0.

These multi-part series may be just what you need! Using a Schmidt trigger in this application makes sense.

These people have a bunch of them and the price is definitely right: M Group transistor on adtasheet 6p20 ram repair cmos ic 74HC Datasheet pin configuration of ic Text: Roger Baker Redmond, WA. I checked the usual places and it may be obsolete. This appears to be a dual Schmitt Trigger. The IC in your frequency counter is a non inverting dual Schmidt trigger. IEC logic symbol Fig 3. Therefore, you can use any garden variety Schmitt trigger in its place.

Logic diagram one Schmitt trigger 7. If it works at the lower voltage, I would modify the circuit to power IC1 from 5V. Marking codes Type number Marking code[1symbol Fig 2.

Marking codesSchmitt trigger 7. It is achmitt of transforming slowly changing input signals intoTriple non-inverting Schmitt trigger with 5 V tolerant input 4. For the MCB device these thresholds are adjustable via external resistors through the positive, negative and common terminals. The answer to question is it is an NE dual timer. The is this part: LimitingSingle Schmitt trigger buffer
