MC74HC574A Octal 3-State Noninverting D Flip-Flop High–Performance Silicon–Gate CMOS The MC74HC574A is identical in pinout to the LS574. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs. 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. The HC574A is identical in function to the HC374A but has the flip–flop inputs on the opposite side of the package from the outputs to facilitate PC board layout. http://onsemi.com MARKING DIAGRAMS 20 PDIP–20 N SUFFIX CASE 738 1 MC74HC574AN AWLYYWW 1 20 20 Output Drive Capability: 15 LSTTL Loads Outputs Directly Interface to CMOS, NMOS and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 A In Compliance with the Requirements Defined by JEDEC Standard No. 7A Chip Complexity: 266 FETs or 66.5 Equivalent Gates 20 1 SOIC WIDE–20 DW SUFFIX CASE 751D 1 A WL YY WW HC574A AWLYYWW = Assembly Location = Wafer Lot = Year = Work Week ORDERING INFORMATION Device MC74HC574AN MC74HC574ADW MC74HC574ADWR2 Package PDIP–20 SOIC–WIDE SOIC–WIDE Shipping 1440 / Box 38 / Rail 1000 / Reel Semiconductor Components Industries, LLC, 2000 1 March, 2000 – Rev. 8 Publication Order Number: MC74HC574A/D MC……
