DESCRIPTION:

The IDT octal buffer/line drivers are built using an advanced

dual metal CMOS technology. The FCT240T/FCT2240T and

FCT244T/FCT2244T are designed to be employed as memory

and address drivers, clock drivers and bus-oriented transmit-

ter/receivers which provide improved board density.

The FCT540T and FCT541T/FCT2541T are similar in

function to the FCT240T/FCT2240T and FCT244T/FCT2244T,

respectively, except that the inputs and outputs are on oppo-

site sides of the package. This pinout arrangement makes

these devices especially useful as output ports for micropro-

cessors and as backplane drivers, allowing ease of layout and

greater board density.

The FCT2240T, FCT2244T and FCT2541T have balanced

output drive with current limiting resistors. This offers low

ground bounce, minimal undershoot and controlled output fall

times-reducing the need for external series terminating resis-

tors. FCT2xxxT parts are plug-in replacements for FCTxxxT

parts.
