what is output enable pin

what is output enable pin in any ic say 74LS245.

 

[aashitech]

Output Enable or OE pin on many digital logic ICs or some digital driver ICs is used to make output enable/disable...if this pin is in its active state then the content of internal latches/gates of that particular IC is reflected on the pins..by keeping this OE pin in its inactive state the ouputs are tristated/high impedance states...

u mean any ic having output enable will work when it will have low output voltage or current.
if not then kindly tell how this pin will work

The SN54/74LS245 is an Octal Bus Transmitter/Receiver designed for
8-line asynchronous 2-way data communication between data buses.
Direction Input (DR) controls transmission of Data from bus A to bus B or bus
B to bus A depending upon its logic level. The Enable input (E) can be used
to isolate the buses.

Note: The word you use " output" is misunderstand you

ok thanks a lot
