MC74HCT374A Octal 3-State Noninverting D Flip-Flop with LSTTL-Compatible Inputs High−Performance Silicon−Gate CMOS The MC74HCT374A may be used as a level converter for interfacing TTL or NMOS outputs to High−Speed CMOS inputs. The HCT374A is identical in pinout to the LS374. Data meeting the setup and hold time is clocked to the outputs with the rising edge of Clock. The Output Enable does not affect the state 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 HCT374A is identical in function to the HCT574A, which has the input pins on the opposite side of the package from the output pins. This device is similar in function to the HCT534A, which has inverting outputs. http://onsemi.com MARKING DIAGRAMS PDIP−20 N SUFFIX CASE 738 20 1 • MC74HCT374AN AWLYYWWG 1 20 20 1 SOIC−20 DW SUFFIX CASE 751D Features • • • • • • • • 20 HCT374A AWLYYWWG 1 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 mA In Compliance With the JEDEC Standard No. 7.0 A Requirements Chip Complexity: 276 FETs or 69 Equivalent Gates Improvements over HCT374 — Improved Propagation Delays — 50% Lower Quiescent Power — Improved Input Noise and Latchup Immunity These Devices are Pb−Free and are RoHS Compliant 20 20 1 TSSOP−20 DT SUFFIX CASE 948E HCT 374A ALYWG G 1 20 SOEIAJ−20 F SUFFIX CASE 967 20 1 74HCT374A AWLYYWWG 1 A WL, L YY, Y WW, W G or G = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package (Note: Microdot may be in either location) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 2 of this data sheet. © Semiconductor Components Industries, LLC, 2011 May, 2011 − Rev. 11 1 Publication Order Number: MC74HCT374A/D MC74HCT374A PIN ASSIGNMENT OUTPUT ENABLE Q0 LOGIC DIAGRAM D0 D1 D2 DATA INPUTS D3 D4 D5 D6 D7 CLOCK OUTPUT ENABLE 3 2 4 5 7 6 8 9 13 12 14 15 17 16 18 19 20 VCC 2 19 Q7 D0 3 18 D7 D6 D1 4 17 Q0 Q1 5 16 Q6 Q1 Q2 6 15 Q5 Q2 D2 7 14 D5 D3 8 13 D4 Q3 9 12 Q4 10 11 CLOCK Q3 NONINVERTING OUTPUTS Q4 Q5 GND Q6 FUNCTION TABLE Q7 11 1 1 Inputs Output Enable PIN 20 = VCC PIN 10 = GND L L L H ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ ÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎÎ Value Units Internal Gate Count* Design Criteria 69 ea.

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 Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously.
