MC74HCT574A Octal 3-State Noninverting D Flip-Flop with LSTTL-Compatible Inputs High–Performance Silicon–Gate CMOS The MC74HCT574A is identical in pinout to the LS574. 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. The HCT574A 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. • • • • • • • Output Drive Capability: 15 LSTTL Loads 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 In Compliance with the Requirements Defined by JEDEC Standard No. 7A Chip Complexity: 286 FETs or 71.5 Equivalent Gates http://onsemi.com MARKING DIAGRAMS 20 PDIP–20 N SUFFIX CASE 738 20 MC74HCT574AN AWLYYWW 1 20 1 20 1 SOIC WIDE–20 DW SUFFIX CASE 751D HCT574A AWLYYWW 1 A WL YY WW = Assembly Location = Wafer Lot = Year = Work Week ORDERING INFORMATION Device MC74HCT574AN MC74HCT574ADW Package Shipping PDIP–20 1440 / Box SOIC–WIDE MC74HCT574ADWR2 SOIC–WIDE Semiconductor Components Industries, LLC, 2000 March, 2000 – Rev. 8 1 38 / Rail 1000 / Reel Publication Order Number: MC74HCT574A/D MC74HCT574A LOGIC DIAGRAM D0 D1 D2 DATA INPUTS D3 D4 D5 D6 D7 CLOCK 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 12 PIN ASSIGNMENT Q0 Q1 Q2 Q3 Q4 NON– INVERTING OUTPUTS Q5 Q6 Q7 11 OUTPUT ENABLE PIN 20 = VCC PIN 10 = GND 1 Inputs L L L H Output Clock D Q L,H, X H L X X H L No Change Z X = don’t care Z = high impedance ÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎ Design Criteria Value Units Internal Gate Count* 71.5 ea Internal Gate Propagation Delay 1.5 ns Internal Gate Power Dissipation 5.0 µW 0.0075 pJ Speed Power Product 1 20 VCC 2 19 Q0 D1 3 18 Q1 D2 4 17 Q2 D3 5 16 Q3 D4 6 15 Q4 D5 7 14 Q5 D6 8 13 Q6 D7 9 12 Q7 10 11 CLOCK GND FUNCTION TABLE OE OUTPUT ENABLE D0 *Equivalent to a two–input NAND gate. http://onsemi.com 2 MC74HCT574A ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ ÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎ ÎÎÎ MAXIMUM RATINGS* Symbol VCC Parameter DC Supply Voltage (Referenced to GND) Value Unit – 0.5 to + 7.0 V Vin DC Input Voltage (Referenced to GND) – 0.5 to VCC + 0.5 V Vout DC Output Voltage (Referenced to GND) – 0.5 to VCC + 0.5 V DC Input Current, per Pin ± 20 mA Iout DC Output Current, per Pin ± 35 mA ICC DC Supply Current, VCC and GND Pins ± 75 mA PD Power Dissipation in Still Air, 750 500 mW Tstg Storage Temperature – 65 to + 150 _C Iin TL Plastic DIP† SOIC Package† This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
