TECHNICAL DATA
Octal 3-State Noninverting
Bus Transceiver
High-Speed Silicon-Gate CMOS
IN74ACT245
The IN74ACT245 is identical in pinout to the LS/ALS245,
HC/HCT245. The IN74ACT245 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS inputs.
The IN74ACT245 is a 3-state noninverting transceiver that is used for
2-way asynchronous communication between data buses. The device has
an active-low Output Enable pin, which is used to place the I/O ports into
high-impedance states. The Direction control determines whether data
flows from A to B or from B to A.
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA; 0.1 µA @ 25°C
• Outputs Source/Sink 24 mA
