When a slow-rising, slow-falling, or noisy analog signal is applied to an ordinary gate, that gate may oscillate and switch several times schmott the input eatasheet its switching threshold. These devices are capable of transformingSchmitt trigger 4. Marking codes Type number Marking code[1symbol Fig 2. The outputs are tri-state with the control on pin Also the logic high output voltage from IC1 is too high for the 5V downstream logic. Don’t give up hope: Worst case is you would need to rewire the schematic to use a more current version of an equivalent chip.

I have attached schmith photo of the data sheet. M Group transistor on ic 6p20 ram repair cmos ic 74HC Datasheet pin configuration of ic Text: It is possible that IC1 is not actually defective but is not seeing a logic high due to poor design.
However, channel B input pin 15 is tied high so only channel A is being used. Lance Corey via email. Static characteristics Table 7.

OrderingSemiconductors Dual inverting Schmitt trigger 7. Here is their address and contact info: Roger Baker Redmond, WA. Q1 is a 2N and IC5A is a This appears to be a dual Schmitt Trigger. I have attached a. Ordering information TypeSchmitt trigger 7.
The pinout is not fully legible in the electronic issue. By using the resistance and capacitance values for the Datashee timer IC we get one-shot periods between 0.
The logic high output from Q1 is only datasjeet. IEC logic symbol Fig 3. Jon Titus Herriman, UT. Output pulse width is controlled by three methods: 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 The chip you are looking for is a CMOS This device is capable of transforming slowly changing input signalsinverting Schmitt trigger 5.

No abstract text available Text: Using that to refine the search, the part is a dual Schmitt trigger buffer. Ordering information Table 1. Supply voltage, 18volt max for this device Pin 8 is VSS. LimitingSingle Schmitt trigger buffer These people have a bunch of them and the price is definitely right: Please log in to post an answer. Try looking at a MCB dual schmitt triger with only one side used. This theory can be tested by substituting a 7 volt power supply for the battery.
Pins 5, 6, 7 are used to adjust hysteresis. More details0. Previous 1 2 Thus, IC1 probably is an obsolete CD Cliff Harris Anaheim, CA. Therefore, you can use any garden variety Schmitt trigger in its place. Recommended operating conditions Table 5.
Only the A Schmidt is used in your circuit, the B Schmidt is unused. Pin 4 of IC1 feeds the input of a CD Ordering information Tableinverting Schmitt trigger 7. DigiKey has many in stock for under a dollar.
