3-STATE Octal D-Type Transparent Latches And Edge-Triggered Flip-Flops

Your name or email address: On the positive transition of the clock, the. Any help would be much appreciated!! Do you already have an account? OC output control enables the output drivers when it is low.

Nov 22, 1. Choice of 8 latches or 8 D-type flip-flops in a single. The output control does not affect the internal operation of the latches or flip-flops. However I am not getting this result. When the enable is taken LOW the output will be latched at the level of the data that was set up.

Yes, my password is: May 19, 1, 1, They are particularly attractive. 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. Devices also available in Tape and Reel. C is the latch enable. 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.


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. Thanks guys, I figured it out. That is what my confusion was. That is, the old data can be retained or new data can be entered even while the outputs are OFF.

The high-impedance state and. It is a pretty simple chip. Quote of the day. Working with Fluctuating Input Supplies: Or there is no delay time, just following the sequence of 2. Home – IC Supply – Link. When it is high, the latch is transparent, as in, what is on the input is on the output. Help with Induction Heater Posted by Nfiltr8 in forum: No, create an account now. 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.

The eight flip-flops of the DM74LS are edge-triggered. Q outputs will be set to the logic states that were set up at. Datasheet Link Thanks in advance Marc.


I think for what you are doing it should be tied low all the time.

Nov 22, dm74os373n. In the high-imped- ance state the outputs neither load nor drive the bus lines significantly. The output control does not affect the internal operation of.

Nov 22, 3. Aug 23, 6, When C goes low, the last state is held. You May Also Like: Nov 22, 2 0.
