MC74HC574A

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Noninverting D Flip-Flop High–Performance Silicon–Gate CMOS The MC54/74HC574A 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 HCT374A but has the flip–flop inputs on the opposite side of the package from the outputs to facilitate PC board layout. The HC574A is the noninverting version of the HC564. 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 µA In Compliance with the Requirements Defined by JEDEC Standard No. 7A Chip Complexity: 266 FETs or 66.5 Equivalent Gates MC54/74HC574A J SUFFIX CERAMIC PACKAGE CASE 732–03 1 20 20 1 N SUFFIX PLASTIC PACKAGE CASE 738–03 20 1 DW SUFFIX SOIC PACKAGE CASE 751D–04 ORDERING INFORMATION MC54HCXXXAJ MC74HCXXXAN MC74HCXXXADW Ceramic Plastic SOIC PIN ASSIGNMENT LOGIC DIAGRAM D0 D1 D2 DATA INPUTS D3 D4 D5 D6 D7 CLOCK OUTPUT ENABLE 2 3 4 5 6 7 8 9 11 1 PIN 20 = VCC PIN 10 = GND 19 18 17 16 15 14 13 12 Q0 Q1 Q2 ...
