OC output control enables the output drivers when it is low. The eight flip-flops of the DM74LS are edge-triggered.

DM74LS373N Datasheet

Datasheet Link Thanks in advance Marc. However I am not getting this result. Q outputs will follow the data D inputs. I have tried every combination of OC and g in order to see outputs matching the inputs.

In the high-imped- ance state the outputs neither load nor drive the bus lines significantly. When the enable is taken LOW the output will be latched at the level of the data that was set up.


Any help would be much appreciated!! Nov 22, 1. The output control does not affect the internal operation of.

Here’s an overview of the major players in the new RTOS world. Or there is no delay time, just following the sequence of 2. Anyway, for some reason I can’t figure out how to properly latch data inputs to the LSN. A buffered output control input can be used to place dtaasheet. That is, the old data can be retained or new data can be entered even while the outputs are OFF. Devices also available in Tape and Reel. Working with Fluctuating Input Supplies: Nov 22, 2.

Yes, my password is: Aug 23, 6, Do you already have an account? That is what my confusion was. Nov 22, 4. When it is high, the latch is transparent, as in, what is on the input is on the output. On the positive transition of the clock, the Q outputs will be set to the logic states that were set up at the D inputs. Nov 22, 3. That is, the old data can be.

The high-impedance state and increased high-logic level drive provide these registers with the capability of being connected directly to and driving the bus lines in a bus-organized system without need for inter- face or pull-up components.

Home – IC Supply – Link. Your name or email address: The output control does not affect the internal operation of the latches or flip-flops. Q outputs will be set to the logic states that were set up at. C is the latch enable. A buffered output control input can be used to place the eight outputs in either a normal logic state HIGH or LOW logic levels or a high-impedance state.


Nov 22, 2 0. May 19, 1, 1, Quote of the day. I think for what you are doing it should be tied low all the time. They are particularly attractive. When C goes low, the last state is held.

I wasn’t driving my inputs with anything, and thus my LED’s were glowing I guess the output is high by default if there is nothing driving the input.

No, create an account now. Thanks guys, I figured it out. It is a pretty simple chip. Help with Induction Heater Posted by Nfiltr8 in forum:
