IDT74FCT543 - Integrated Device Technology

IDT74FCT543 FAST CMOS OCTAL LATCHED TRANSCEIVER

The FCT543 is a non-inverting octal transceiver built using an advanced dual metal CMOS technology. These devices contain two sets of eight D-type 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 in.
