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. The output control does not affect the internal operation of the latches or flip-flops.

OE is held tied to ground. Notify of all new follow-up comments Notify of new replies to all my comments. But when the OE is high the output will be in a high impedance state. In the high-imped- ance state the outputs neither load nor drive the bus lines significantly.
But when the Latch Enable Pin was pulled low, the data will be latched so that the data appears instantaneously providing a Latching action. 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. Frank Donald is an Electronics and Communication Engineer who loves building stuff in his free time. 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.

That is, the old 7373 can be retained or new data can be entered even while the outputs are OFF. The output control does not affect the internal operation of.

The IC 74LS is a transparent latch consists of a eight latches with three state outputs for bus organized systems applications. This IC daasheet with maximum of 5 V and widely used in many kinds of electronic appliances.

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. When the enable is taken LOW the output will be latched at the level datsheet the data that was set up.
