Overview
TECHNICAL DATA IN74ACT643 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 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...
