No Preview Available ! TECHNICAL DATA Octal 3-State Noninverting Transparent Latch High-Performance Silicon-Gate CMOS IN74ACT573 The IN74ACT573 is identical in pinout to the LS/ALS573, HC/HCT573. The IN74ACT573 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. These latches appear transparent to data (i.e., the outputs change asynchronously) when Latch Enable is high. When Latch Enable goes low, data meeting the setup and hold time becomes latched. • 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; 0.1 µA @ 25°C • Outputs Source/Sink 24 mA ORDERING INFORMATION IN74ACT573N Plastic IN74ACT573DW SOIC TA = -40° to 85° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 20=VCC PIN 10 = GND www.datasheet4u.com FUNCTION TABLE Inputs Output Output Latch Enable Enable D Q L HH H L HL L L L X no change H XX Z X = don’t care Z = high impedance 1 1 page IN74ACT573 Figure 1.
