74HC244 PDF

The device can be used as two 4-bit buffers or one 8-bit buffer. The device features two output enables 1OE and 2OE , each controlling four of the 3-state outputs. Inputs include clamp diodes that enable the use of current limiting resistors to interface inputs to voltages in excess of VCC. Features and benefits? Input levels:?

Gardazragore Any datasheer, there is very little information about Line Drivers in general. Tristate mode also saves power by not driving the line when there is nothing to send.

Sign up using Email and Password. How does a Line Driver actually works? How does a line driver actually work? There are two principal functions of this line driver. That power is used by each buffer element to dataaheet the load it can drive. You can think of it as the logic gate equivalent of an amplifier. As always, the Datasheet provides raw and not very good information about the actual component: Sign up using Facebook. 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.

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. The increased current is able to overcome the capacitance caused by having many devices on a bus.

Post as a guest Name. What do you think a buffer is? Eminem — What makes you think the input hc connected directly to the output? So, how do thy actually works? A line driver is simply a buffer. But how it works? I mean, it gives us the temperatures, but not how the actual component works The line driver also serves to isolate the local circuits from electrostatic discharge from connections that might go off the board.
