High-Performance Silicon-Gate CMOS
KK74HCT245A
The KK74HCT245A 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 KK74HCT245A 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.
• TTL/NMOS Compatible Input Levels
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 4.5 to 5.5 V
• Low Input Current: 1.0 µA
