IN74HCT574A

TECHNICAL DATA IN74HCT574A Octal 3-State Noninverting D Flip-Flop High-Performance Silicon-Gate CMOS The IN74HCT574A is identical in pinout to the LS/ALS574. This device 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 ORDERING INFORMATION IN74HCT574AN Plastic IN74HCT574ADW SOIC TA = -55° to 125° C for all packages PIN ASSIGNMENT LOGIC DIAGRAM FUNCTION TABLE PIN 20=VCC PIN 10 = GND Output Enable Inputs Clock D H L L,H, X X X Output Q H L no change Z w w w .d h s a t a ee . u t4 m o c L L L H X = don’t care Z = high impedance 1 www.DataSheet4U.com IN74HCT574A 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 Current, per Pin DC Supply Current, VCC and GND Pins Power Dissipation in Still Air, Plastic DIP+ SOIC Package+ Storage Temperature Lead Temperature, 1 mm from Case for 10 Secon...
