It should be noted that the device identified above is a “tri-state” driver.

datasheet, Pinout ,application circuits Octal 3-STATE Buffer/Line Driver/Line Receiver

The enable function is common to all four drivers and offers the choice of an active-high or active-low enable G, G input. It’s as if the chip were disconnected from the wire.

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. What you put in one end comes out the other. That 74424 gives everything you need to actually use a 74HC Any way, there is very little information about Line Drivers in general.

The functional diagram on that datasheet omits dataheet power pins, but they are there and must be powered for the part to function. Sign up using Facebook.

Home Questions Tags Users Unanswered. This means that it can set the 774244 “high”, “low”, or can effectively disconnect itself from the line. That power is used by each buffer element to increase the load it can drive.

It sounds like you’re looking for a equivalent circuit.

But how it works? I mean, it gives us the temperatures, but not how the actual component works What do you think a buffer is? The datasheet also states: All I see in the inner structure is enables and input to outpuut wires.

Hot Licks 3 8. Try Findchips PRO for ic I mean, how the can increase the current with just sending the input to the output? Previous 1 2 Jeff Bell 1 4. In case it’s the apparent lack of power to the chip that’s confusing you: HP QIC, Mbytetape, circuit diagram Truth Table IC, counter schematic diagram,uses and functions, counter truth table of ic A schematic diagram for the IC of So, how do thy actually works? Eminem Language barrier here, I think.

Limit load capacitance by buffering loads with an external device such as the IC bus driverintegrated circuit IC. I’m not sure what you mean by “how it works”. The circuits that are driving the inputs may not have the power to drive the impedance of a longer wire length.

So I’ve searched for days for information about the 74HC line driver. Eminem – What makes you think the input is connected directly to the output? The first is to provide a power gain.

How does a Line Driver actually works? A line driver is simply a buffer. The outputs of the bus driver IC drive the heavy capacitive loads, reducing the loading on the device, thus.

Tristate mode also saves power by not driving the line when there is nothing to send. Link to AM26LS31 datasheet: Email Required, but never shown.

It can 742444 used, eg, for a “bi-directional” bus between processor and memory or between processor and devices: The increased current is able to overcome the capacitance caused by having many devices on a bus.
