Do I need pull up resistors or does this sound like bad chips. That is, the old data can be. When the enable is taken LOW the output will be latched at the level of the data that was set up.

Q outputs will be set to the logic states that were set up at. The output control does not affect the internal operation of. 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.


– Octal D-type transparent latch; 3-state – ChipDB

The output control does not affect the internal operation of the latches or flip-flops. But when the Latch Enable Pin was pulled low, the data will be latched so that the data appears instantaneously providing a Latching action. Frank Donald October 27, 2 Comments.

The eight flip-flops of the DM74LS are edge-triggered. In the high-imped- ance state the outputs neither load nor drive the bus lines significantly.

A buffered output control input can be used to place the. When the OE pin is low input data will appear in the output.

On datashheet positive transition of the clock, the Q outputs will be set to the logic states that were set up at the D inputs. Notify of all new follow-up comments Notify of new replies to all my comments. Video games, blogging and programming are the things he loves most.

OE is held tied to ground. Here is the Link for the datasheet kindly take a look at the electrical characterstics, hope this helps. Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time. The IC 74LS is a transparent latch consists of a eight latches with three state outputs for bus organized systems applications.


On the positive transition of the clock, the. Q outputs will follow the data D inputs. I have 5V on D, but only get 3. Devices also available in Tape and Reel. As we all know the operation of flip flop that any input to the D pin at the present state will be given as output in next clock cycle.

This IC operates with maximum of 5 V and widely used in many kinds of electronic appliances. The following two dztasheet change content below. Order Number Package Number. 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.
