No Preview Available ! TECHNICAL DATA Octal 3-State Noninverting Transparent Latch High-Speed Silicon-Gate CMOS IN74ACT373 The IN74ACT373 is identical in pinout to the LS/ALS373, HC/HCT373. The IN74ACT373 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 IN74ACT373N Plastic IN74ACT373DW SOIC TA = -40° to 85° C for all packages LOGIC DIAGRAM PIN ASSIGNMENT PIN 20=VCC www.datasheet4u.PcINo1m0 = GND FUNCTION TABLE Inputs Output Latch D Enable Enable L HH L HL L LX H XX X = Don’t Care Z = High Impedance Output Q H L No Change Z 1 1 page IN74ACT373 Figure 1.
