IDT74FCT543TQ

快速CMOS八路锁存收发器 FAST CMOS OCTAL LATCHED TRANSCEIVER

DESCRIPTION:

The FCT543T/FCT2543T is a non-inverting octal transceiver built using an advanced dual metal CMOS technology. This device contains 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 indicated in the Function Table.
