FEATURES:  
• IDT54/74FCT245/640/645 equivalent to FAST speed  
and drive  
DESCRIPTION:  
The IDT octal bidirectional transceivers are built using an  
advanced dual metal CMOS technology. The IDT54/  
74FCT245/A/C,IDT54/74FCT640/A/CandIDT54/74FCT645/  
A/C are designed for asynchronous two-way communication  
between data buses. The transmit/receive (T/R) input deter-  
mines the direction of data flow through the bidirectional  
transceiver. Transmit (active HIGH) enables data from A  
ports to B ports, and receive (active LOW) from B ports to A  
ports. The output enable (OE) input, when HIGH, disables  
both A and B ports by placing them in High-Z condition.  
The IDT54/74FCT245/A/C and IDT54/74FCT645/A/C  
transceivers have non-inverting outputs. The IDT54/  
74FCT640/A/C has inverting outputs.  
• IDT54/74FCT245A/640A/645A 25% faster than FAST  
• IDT54/74FCT245C/640C/645C 40% faster than FAST  
• TTL input and output level compatible  
• CMOS output level compatible  
• IOL = 64mA (commercial) and 48mA (military)  
• Input current levels only 5µA max.  
• CMOS power levels (2.5mW typical static)  
• Direction control and over-riding 3-state control  
• Product available in Radiation Tolerant and Radiation  
Enhanced versions  
• Military product compliant to MIL-STD-883, Class B and  
DESC listed  
• Meets or exceeds JEDEC Standard 18 specifications
