TECHNICAL DATA
Octal 3-State Noninverting
Bus Transceiver
High-Performance Silicon-Gate CMOS
KK74HC245A
The KK74HC245A is identical in pinout to the LS/ALS245. The
device inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LS/ALSTTL outputs.
The KK74HC245A 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.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 µA
• High Noise Immunity Characteristic of CMOS Devices
