IDT74FCT543C Overview
The FCT543 is a non-inverting octal transceiver built using an advanced dual metal CMOS technology. These devices contain two sets of eight Dtype latches with separate input and output controls for each set. For data flow from A to B, for example, the A-to-B Enable (CEAB) input must be low in order to enter data from A0 A7 or to take data from B0 B7, as indicated in the Function Table.
