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

How does a line driver actually datashset The enable function is common to all four drivers and offers the choice of an active-high or active-low enable G, G input. That datasheet gives everything you need to actually use a 74HC What do you think a buffer is? Jeff Bell 1 4. The outputs of the bus driver IC drive the heavy.

I mean, it gives us the temperatures, but not how the actual component works This allows you to have multiple line drivers on the same wire, and as long as they properly take turns driving it they can share the single connection. Low-power Schottky circuitry reduces power consumption without sacrificing speed.

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. 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. As always, the Datasheet provides raw and not very good information about the dataxheet component: Sign up or log in Sign up using Google. QS function pin configuration ic Text: It should be noted that the device identified above is a “tri-state” driver.


The datasheet also states: The increased current is able to overcome the capacitance caused dtasheet having many devices on a bus.

Eminem Language barrier here, I think. You can think of it as the logic gate equivalent of an amplifier.

I mean, how the can increase the current with just sending the input to the output? Limit load capacitance by buffering loads with an external device such as the IC bus driver, or bybounce, is to connect the device’s switching outputs to a bus driver integrated circuit IC.

Any way, there is very little information about Line Drivers in general. This chip does not perform any logical function; it is just giving the signal a strength boost.

The functional diagram datasheet that datasheet omits the power pins, but they are there and must be powered for the part to function. It’s as if the chip were disconnected from the wire. Post as a guest Name.


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.

It sounds like you’re looking for a equivalent circuit. So, how do thy actually works?

And how the can act as a line driver? This means that it can set the line “high”, “low”, or can effectively disconnect itself from the line. 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.
