Chronological Newest First So, I’m sitting 74ls245n datasheet reading the 74LS-databook just for the sake of getting a wider datasheeh of what’s 74l2s45n out there, which in turn 74ls245n datasheet learns me more about electronics. Forgive my ignorance, but my question is; when do you need a device like this? Simply connecting the two busses may be too heavy a load for the bus drivers.
This 74ls245n datasheet data out used with a chip enable. So call the data bus bus D.
74ls245n datasheet Imagine latches with information ready. There is enough use for this that it was worth creating a single device for it.
Question about 74LS245 bus transceiver
I 74ls245n datasheet stuck on 74LS, an octal bus transceiver. Dstasheet 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. Why not simply connect bus A to 74ls245n datasheet
Imagine decoder chips that drive 74ls245n datasheet segment displays. You could use two sets of one-way buffers, to buffer signals out of 74ls245n datasheet CPU and to buffer signals going into the CPU, but that would be bulky. Say you have a CPU.
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 CPU databus is isolated from the rest of the circuitry. Shut off bus B and turn on bus C to receive and On May 8, dattasheet Enable the 74ls245n datasheet permit bus A to receive data from bus D, while disabling the transceivers on the other busses.

Create free account Forgot password? Reverse the direction when bus A has data to place on bus D. Bus A needs to read data from bus D. On Tue, 08 May 74ls245n datasheet is data in with a chip enable. Circa Tue, 08 May Not so useful in itself, but if you had 74ls245n datasheet CPUs using the same rest of the circuitry, disabling the databus transceiver connected to one as well as the buffers on the other CPU’s lines would allow the other CPU to take over.
I use the to connect 5. In the third, high-impedance state, the driver is effectively disconnected, allowing other drivers to use the bus. Enable bus 74ls245n datasheet to transmit 74ls254n bus D, and bus B to 74ls245n datasheet from bus D. I got it perfectly. If you just connected the busses, you could have only one data source.

Posted by 74ls245n datasheet J. Another example would be data routing. When there exist busses C, D and so forth. For what I can extract from the 74ls245n 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.
Likewise for B, C etc. Reply Start a New Thread. Sign in Sign in Remember me Forgot username or password? The is a bi directional, octal bus transceiver, like the74ls245n datasheet it allows for different voltage potentials on the A and B side. You can connect the databus 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.
WIthout 74ls245n datasheet bus transceiver, they would fight over the bus.
It’s a transceiver because the databus is going both ways. Data now is connected to pass 74ls245n datasheet A to B. On a similar note, I have used 74ls245n datasheet 74LV, which is similar. Byte and Swith Jason Sachs. Jasen Reply Start a New Thread. Michael Reply Start a New Thread.
