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. Sign up using Email and Password.

The second functionality is that it has a tristate output, which means that when the enable pin is not asserted the chip does not drive the output signal at all. The line driver also serves to isolate the local circuits from electrostatic discharge from connections that might go off the board.

It can be used, eg, for a “bi-directional” bus between processor and memory datashdet between processor and devices: There are two principal functions of this line driver.

Hot Licks 3 8. That datasheet gives everything you need to actually use a 74HC It’s as if the chip were disconnected from the wire. The outputs of the bus driver IC drive the heavy. The first is to provide a power gain. It sounds like you’re looking for a equivalent circuit. This allows you to have multiple line drivers on the same wire, and as long as they properly take turns 74424 it they can share the single connection.

I think vatasheet 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.

This chip does not perform any logical function; it is just giving the satasheet a strength boost. Jeff Bell 1 4. How does a line driver actually work?

The datasheet also states: Limit load capacitance by buffering loads with an external device such as the IC bus driverintegrated circuit IC. The functional diagram on that datasheet omits the power pins, but they are there and must be powered for the part to function. Eminem 1 3 8. Tristate mode also saves power by not driving the line when there is nothing to send.

If you want more detail, you should start reading about how transistors work, and how they’re used to make the logic gates in the shown diagram. QS function pin configuration ic Text: A line driver is simply a buffer.

The increased current is able to overcome the capacitance caused by having many devices on a bus. Or the Altera can provide a good current daatsheet to the servo without damaging it’s abilities? But how it works?

All I see in the inner structure is enables and input to outpuut wires. In case it’s the apparent lack of power to the chip that’s confusing you: What you put in one end comes out the other. Try Findchips PRO for ic As always, the Datasheet provides raw and not very good information about the actual component: So, how do thy actually works? The enable function is common to all four drivers and offers the choice of an active-high or active-low enable G, G input.

Eminem – What makes you think the input is connected directly to the output? This is used in situations where any of several components can “drive” the bus though hopefully not more than one at a time.
