KK74HC245A
KK74HC245A is Octal 3-State Noninverting Bus Transceiver manufactured by Kodenshi AUK Group.
TECHNICAL DATA
Octal 3-State Noninverting Bus Transceiver
High-Performance Silicon-Gate CMOS
The KK74HC245A is identical in pinout to the LS/ALS245. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. The KK74HC245A is a 3-state noninverting transceiver that is used for 2-way asynchronous munication 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
