I got stuck on 74LS, an octal bus transceiver. So call the data bus 74ls245n datasheet D. I got it perfectly.

Access Denied

Why not simply connect bus A to B? Jasen Reply Start a New Thread. I use the to 74ls245n datasheet 5. Sign in Sign in Remember me Forgot username or password? You can connect the 74ls245n datasheet directly to some memory, but once you start adding a lot of circuitry, it would load down the CPU’s data bus too much the CPU datalines couldn’t supply enough current.

It’s a transceiver because the databus is going 74ls245n datasheet ways. This is data in with a chip enable.

WIthout the bus transceiver, they would 74ls245n datasheet over the bus. Imagine latches with information ready. Likewise for B, C etc.

Say you have a CPU. You could use two sets of one-way buffers, to buffer signals out of the CPU and to buffer signals going into the CPU, 74ls245n datasheet that would be bulky.

There is enough use for this that it was worth creating a single device for it. If you just connected the busses, you could have only one data source. Reverse the direction when bus A has data to place on bus D. So you add a buffer so there won’t be much load on the CPU, but there will be enough signal on the databus for all the peripheral circuitry.

And given that many of the answers here have addressed the tri-state nature of the device, you can also turn off the transceiver, so the 774ls245n databus 74ls245n datasheet isolated from the rest of the circuitry. Bus A needs to read data from bus D. On May 8, 3: In the third, high-impedance state, the driver 74ls245n datasheet effectively disconnected, allowing other drivers to use 74ls245n datasheet bus.

On a similar note, I have used the 74LV, which is similar. Another example would be data routing. When there exist busses C, D and 74ls245n datasheet forth. Circa Tue, 08 May This is data out used with a chip enable. Shut off bus B and turn on bus C to receive and Create free account Forgot password? Imagine decoder chips that drive 7 segment displays. Enable the to permit bus A to receive data from bus D, while disabling the transceivers on the other busses.

Posted by Stephen J. 74ls245n datasheet what I can extract from the datasheet, it’s a device that interconnects two buses and, depending on the DIR-pin, either transmits data from bus A to B or B to A. The is a bi directional, octal bus transceiver, like the 74ls245n datasheet, but 74ls245n datasheet allows for different voltage potentials on the A and B side.

Data now is connected to pass from A to B.
