The
KK
74ACT640 is identical in pinout to the LS/ALS640,
HC/HCT640. The
KK
74ACT640 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS inputs.
The
KK
74ACT640 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.
