Synchronizing dual D-type flip-flop/clock driver
Product specification
74F5074
FEATURES
• Metastable immune characteristics
• Output skew guaranteed less than 1.5ns
• High source current (IOH = 15mA) ideal for clock driver
applications
• Pin out compatible with 74F74
• 74F50728 for synchronizing cascaded D–type flip–flop
• See 74F50729 for synchronizing dual D–type flip–flop with
edge–triggered set and reset
• See 74F50109 for synchronizing dual J–K positive
edge–triggered flip–flop
• Industrial temperature range available (–40°C to +85°C)
