1 / 7 page TECHNICAL DATA IN74HCT245A Octal 3-State Noninverting Bus Transceiver High-Performance Silicon-Gate CMOS ORDERING INFORMATION IN74HCT245AN Plastic IN74HCT245ADW SOIC IN74HCT245ATDS SOIC TA = -55° to 125° C for all packages The IN74HCT245A 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 IN74HCT245A 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 PIN ASSIGNMENT LOGIC DIAGRAM PIN 20=VCC PIN 10 = GND FUNCTION TABLE Control Inputs Output Enable Direction Operation L L Data Transmitted from Bus B to Bus A L H Data Transmitted from Bus A to Bus B H X Buses Isolated (High Impedance State) X = don’t care Rev. 00 |
