The high-impedance state and increased high-logic-level drive provides this register 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. It is particularly attractive for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight flip-flops of the DM74ALS374 are edge-triggered D-type flip-flops. 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. 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. 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 the flip-flops. That is, the old data can be retained or new data can be entered even while the outputs are OFF. Features ■ Switching specifications at 50 pF ■ Switching specifications guaranteed over full temperature and VCC range ■ Advanced oxide-isolated, ion-implanted Schottky TTL process ■ Functionally and pin-for-pin compatible with LS TTL counterpart ■ Improved AC performance over DM74LS374 at approxi- mately half the power ■ 3-STATE buffer-type outputs drive bus lines directly Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.

Thanks for Your Review!

They worked great. Not much to say - as far as I can tell they adhere to the specs, and did the job I needed them to. Good transistors for higher current situations.


May 21, 2020

Does what it says. As with this this type of device it is important to have it mounted so that heat can dissipate. The higher the amperage the hotter the device.


May 12, 2020

I like this way to add a project, choose existing project to add components. I use this method frequently to keep track of my projects. Thanks Heisener!


April 23, 2020

Very effective shopping path, service steady as a rock, keep up the great work.


April 23, 2020

Good! quick and convenient delivery. product tracking with good advice.


April 22, 2020

Worked as advertised and good price. Can you imagine buying these at local store it would cost way to much.


April 22, 2020

I've made a few purchases from Heisener and always get a friendly technician helped me with locate what I was looking for. That kind of attitude is greatly appreciated.


April 16, 2020

received with well packed and good parts, every piece of the DM74ALS374WMX works well.


April 7, 2020

I had no problems with this product. Would I recommend it. Yes.


April 5, 2020

Work great, great price, I use a lot of them for battery chargers, not the first time ordered.
