1 / 9 page © Semiconductor Components Industries, LLC, 2007 January, 2007 − Rev. 10 1 Publication Order Number: MC74HCT245A/D MC74HCT245A Octal 3−State Noninverting Bus Transceiver with LSTTL Compatible Inputs High−Performance Silicon−Gate CMOS The MC74HCT245A is identical in pinout to the LS245. This device may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. The MC74HCT245A 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. Features • Output Drive Capability: 15 LSTTL Loads • TTL/NMOS Compatible Input Levels • Outputs Directly Interface to CMOS, NMOS and TTL • Operating Voltage Range: 4.5 V to 5.5 V • Low Input Current: 1.0 mA • In Compliance with the Requirements Defined by JEDEC Standard No. 7A • Chip Complexity: 304 FETs or 76 Equivalent Gates • Pb−Free Packages are Available Figure 1.
