Description

The IDT octal bidirectional transceivers are built using an advanced dual metal CMOS technology.  The IDT54/ 74FCT245/A/C, IDT54/74FCT640/A/C and 74FCT645 are designedfor asynchronous two-way communication between data buses.  The transmit/receive  (T/R) input of the 74FCT645 determines the direction of data flow through the bidirectionaltransceiver.  Transmit (active HIGH) enables data from Aports to B ports, and receive (active LOW) from B ports to Aports.  The output enable (OE) input, when HIGH, disablesboth A and B ports byplacing them in High-Z condition. The 74FCT645 transceivers have non-inverting outputs. The IDT54/74FCT640/A/C has inverting outputs.
