using 74LS123

Here are the details. Iqc is measured after a momentary ground, then 4. Reproduction of information in Tl data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices.

I’m pretty sure the input pulse is TTL-compatible, because I’m using a function generator to supply the input pulse.

It looks like they aren’t fir for the application because they need a trigger pulse anyways which eliminates the whole idea. Beg for you help Reproduction of this information with alteration is an unfair and deceptive business practice.

How to trigger 74LS?

Can someone help me with the basic wiring and what this thing actually does? Further, Buyers must fully 74l123 Tl and its representatives against any damages arising out of the use of Tl products in such safety-critical applications.


Efforts are underway to better integrate information from third parties. Product device recommended for new designs.

How to trigger 74LS123?

I’m not sure if this refers to the input pulse. Jan 28, 9, AF modulator in Transmitter what is the A? Due to the timing scheme used by the ‘LSI 22 and ‘LSI 23, a switching diode is not required to prevent reverse biasing when using electolytic capacitors.

I’m not sure why it doesn’t? Eric Yeow Hi friends: The terminals are gold plated. Products Applications Amplifiers amplifier.

74LS wiring diagram and pinout

Need wiring diagram of Metex MD 0. Ice is measured in the triggered state with 2. Mold flash, protrusions, or gate burrs shall not exceed. Equating complex number interms of the other 6. Applications requiring more precise pulse durations up to 28 seconds and not requiring the clear feature can best be satisfied with the ‘1 Body dimensions do not include mold flash or protrusion, not to exceed 0, Try this configuration and it might have a better chance of working.

Cext is in pF tw is in ns To prevent reverse voltage across Cext- it is recommended that the method shown in Figure 2 be employed when using electrolytic capacitors and in applications utilizing the clear function.

Your name or email address: The output pulse simply disappears the chip no longer reacts to the trigger pulse.

Input port and input output port declaration in top module 2. Andy Neil Sounds like you need a Schmitt Triggerrather than a monostable? All linear dimensions are in millimeters. Similar Threads Help reading motor wiring diagram 5. Information of third parties may be subject to additional restrictions.


It will not solve your minimum input pulse width problem but it will make the output pulse width adjustment better. Read through this thread http: The ‘1 22 and ‘LSI 22 have internal timing resistors that allow the circuits to be used with only an external capacitor, if so desired.

Not recommended for new designs. Tl and Tl suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release. I got a serious problem with 74LS Customers should contact their board fabrication site for solder mask tolerances between and around signal pods. Samples may or may not be available.

How does this hardware question relate to Keil’s C compiler??? Eric Yeow so sorry friends In all applications using the diode, the pulse duration is: Information published by Tl regarding third-party products or services does not constitute a license from Tl to use such products or services or a warranty or endorsement thereof.
