© Semiconductor Components Industries, LLC, 2000 March, 2000 – Rev. 8 1 Publication Order Number: MC74HCT374A/D 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. • 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: 276 FETs or 69 Equivalent Gates • Improvements over HCT374 — Improved Propagation Delays — 50% Lower Quiescent Power — Improved Input Noise and Latchup Immunity http://onsemi.com MARKING DIAGRAMS 1 20 A = Assembly Location WL = Wafer Lot YY = Year WW = Work Week SOIC WIDE–20 DW SUFFIX CASE 751D HCT374A AWLYYWW PDIP–20 N SUFFIX CASE 738 1 20 MC74HCT374AN AWLYYWW TSSOP–20 DT SUFFIX CASE 948G 1 20 1 20 1 20 Device Package Shipping ORDERING INFORMATION MC74HCT374AN PDIP–20 1440 / Box MC74HCT374ADW SOIC–WIDE 38 / Rail MC74HCT374ADWR2 SOIC–WIDE 1000 / Reel MC74HCT374ADT TSSOP–20 75 / Rail MC74HCT374ADTR2 TSSOP–20 2500 / Reel HCT 374A ALYW 1 20 |
