Enable gates pin 11 high 2. Also I may not reply at time. Dec 248: I will shset ic’s by day after tomorrow, will try your schematic and update you soon. But when the OE is high the output will be in a high impedance state.

IC Datasheet: 74LS373 Data Sheet

Need to either set LE low to latch the input or choose different latch. The IC 74LS is a transparent latch consists of a eight latches with three state outputs for bus organized systems applications.

AF modulator in Transmitter what is the A? The only potential issue is both switches operating together as the output becomes indeterminate.

[SOLVED] Help with Latch IC 74LS based latching ciruit

Frank Donald is an Electronics and Communication Engineer who loves daa stuff in his free time. This means that while your Enable is active and in your circuit it is always active – pin 11 high then the data presented to an input will always immediately get reflected to the output.

Compare latch based and register based design 5. As long as output is enabled which it is – pin 1 is 7l4s373 For this latch to hold data, you must do the following: You people are very helpful, Thanks. Distorted Sine output from Transformer 8.

Do I need pull up resistors or does this sound like bad chips. Equating complex number interms of the other 6. You have LE fixed High, hence output equals input The time now is Sehet sinks, Part 2: How reliable is it? Video games, blogging and programming are the things he loves most.
