FUNCTIONAL BLOCK DIAGRAM
OEA 1
DESCRIPTION:
The IDT octal buffer/line drivers are built using an advanced dual metal
CMOS technology. The FCT541 is designed to be employed as a memory
and address driver, clock driver and bus-oriented transmitter/receiver
which provides improved board density. The FCT541 is similar in function
to the FCT244, except that the inputs and outputs are on opposite sides of
the package. This pinout arrangement makes these devices especially
useful as output ports for microprocessors and as backplane drivers,
allowing ease of layout and greater board density.
