IN74ACT643 Datasheet | IK Semiconductor

TECHNICAL DATA Octal 3-State Bus Transceiver High-Speed Silicon-Gate CMOS The IN74ACT643 is identical in pinout to the LS/ALS643, HC/HCT643. The IN74ACT623 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The IN74ACT643 is a 3-state 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. - TTL/NMOS patible Input Levels - Outputs Directly Interface to CMOS, NMOS, and TTL - Operating Voltage Range: 4.5 to 5.5 V -...
