How does a Line Driver actually works? – Electrical Engineering Stack Exchange

The datasheet tells you pretty much everything you need to actually use the part, though NXP does tend to be a bit sparse on internal details.

Jeff Bell 1 4. But how it works? By using our site, you acknowledge that you have read and understand our Cookie Policy dataeheet, Privacy Policyand our Terms of Service. Sign up using Facebook. How does a line driver actually work? The first is to provide a power gain.

74HC244 SMD Octal Buffer IC

Eminem – What makes you think the input is connected directly to the output? Sign up using Email and Password.

The circuits that are driving the inputs may not have the power to drive the impedance of a longer wire length. A line driver is simply a buffer.

Tristate mode also saves power by not driving the line when there is nothing to send. And how the can act as a line driver? All I see in the inner structure is enables and input to outpuut wires. It sounds like you’re looking for a equivalent 774hc244.

Data Sheets

If you want more detail, you should start reading about how transistors work, and how they’re used to make the logic 74hf244 in the shown diagram. Home Questions Tags Users Unanswered. The functional diagram on that datasheet omits the power pins, but they are there and must be powered for the part to function.

The line driver also serves to isolate the local circuits from electrostatic discharge from connections that might go off the board. I think that in order to reduce the current that the FPGA suplies to the servo, I need to put the in between them, thus reducing the “effort” from the Altera. Eminem Language barrier here, I think. How does a Line Driver actually works?

The datasheet also states: I mean, how the can increase the current with just sending the input to the output? Eminem 1 3 8. It’s as if the chip were disconnected from the wire.

Link to AM26LS31 datasheet: Anyways, if you look around a bit, you can find some slightly better datasheets that have more detailed internal diagrams. Low-power Schottky circuitry reduces power consumption without sacrificing speed.
