IN74ACT574

TECHNICAL DATA IN74ACT574 Octal 3-State Noninverting D Flip-Flop High-Performance Silicon-Gate CMOS The IN74ACT574 is identical in pinout to the LS/ALS574, HC/HCT574. The IN74ACT574 may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs. Data meeting the setup time is clocked to the outputs with the rising edge of the Clock. The Output Enable input does not affect the states of the flip-flops, but when Output Enable is high, all device outputs are forced to the high-impedance state; thus, data may be stored even when the outputs are not enabled. 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 IN74ACT574N Plastic IN74ACT574DW SOIC TA = -40° to 85° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE PIN 20=VCC PIN 10 = GND Inputs Output Enable L L L H L,H, X Clock D H L X X Output Q H L no change Z w w w .d h s a t a ee . u t4 m o c X = don’t care Z = high impedance 1 www.DataSheet4U.com IN74ACT574 MAXIMUM RATINGS* Symbol VCC VIN VOUT IIN IOUT ICC PD Tstg TL * Parameter DC Supply Voltage (Referenced to GND) DC Input Voltage (Referenced to GND) DC Output Voltage (Referenced to GND) DC Input Current, per Pin DC Output Sink/Source Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Sto...
