MC74HC374A Octal 3-State Non-Inverting D Flip-Flop High−Performance Silicon−Gate CMOS The MC74HC374A is identical in pinout to the LS374. 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, the outputs are forced to the high−impedance state; thus, data may be stored even when the outputs are not enabled. The HC374A is identical in function to the HC574A which has the input pins on the opposite side of the package from the output. This device is similar in function to the HC534A which has inverting outputs. http://onsemi.com SOIC−20 DW SUFFIX CASE 751D PIN ASSIGNMENT OUTPUT ENABLE Q0 D0 D1 Q1 Q2 D2 D3 Q3 GND Features • • • • • • • • • 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 mA High Noise Immunity Characteristic of CMOS Devices In Compliance with the Requirements Defined by JEDEC Standard No. 7 A Chip Complexity: 266 FETs or 66.5 Equivalent Gates NLV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free and are RoHS Compliant TSSOP−20 DT SUFFIX CASE 948E 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 MARKING DIAGRAMS 20 20 HC 374A ALYWG G 74HC374A AWLYYWWG 1 1 SOIC−20 D1 D2 DATA INPUTS D3 D4 D5 D6 D7 CLOCK OUTPUT ENABLE 3 2 4 5 7 6 8 9 13 14 17 12 15 16 18 19 11 1 Q0 Q1 Q2 Q3 Q4 TSSOP−20 A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week G or G = Pb−Free Package (Note: Microdot may be in either location) LOGIC DIAGRAM D0 VCC Q7 D7 D6 Q6 Q5 D5 D4 Q4 CLOCK FUNCTION TABLE NONINVERTING OUTPUTS Inputs Output Enable Q5 L L L H Q6 Q7 Output Clock D Q L,H, X H L X X H L No Change Z X = don’t care Z = high impedance PIN 20 = VCC PIN 10 = GND ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 5 of this data sheet. © Semiconductor Components Industries, LLC, 2014 August, 2014 − Rev. 14 1 Publication Order Number: MC74HC374A/D MC74HC374A MAXIMUM RATINGS Symbol Parameter Value Unit –0.5 to +7.0 V DC Input Voltage (Referenced to GND) –0.5 to VCC + 0.5 V DC Output Voltage (Referenced to GND) –0.5 to VCC + 0.5 V VCC DC Supply Voltage (Referenced to GND) Vin Vout Iin 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, 500 450 mW Tstg Storage Temperature –65 to +150 _C TL Lead Temperature, 1 mm from Case for 10 Seconds (SOIC, SSOP or TSSOP Package) SOIC Package† TSSOP Package† This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high−impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND v (Vin or Vout) v VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused outputs must be left open. _C 260 Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected. †Derating: SOIC Package: –7 mW/_C from 65_ to 125_C TSSOP Package: −6.1 mW/_C from 65_ to 125_C RECOMMENDED OPERATING CONDITIONS Symbol VCC Vin, Vout Parameter Min Max Unit 2.0 6.0 V 0 VCC V –55 +125 _C 0 0 0 1000 500 400 ns DC Supply Voltage (Referenced to GND) DC Input Voltage, Output Voltage (Referenced to GND) TA Operating Temperature, All Package Types tr, tf Input Rise and Fall Time (Figure 1) VCC = 2.0 V VCC = 4.5 V VCC = 6.0 V Functional operation above the stresses listed in the Recommended Operating Ranges is not implied.
