The
KK
74HCT245A is identical in pinout to the LS/ALS245.This
device may be used as a level converter for interfacing TTL or NMOS
outputs to High Speed CMOS inputs.
The
KK
74HCT245A 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.
