SEMICONDUCTOR TECHNICAL DATA
The MC88914 is a high–speed, low power, hex divide–by–two D–type
flip–flop with matched propagation delays, an internal power–on–reset,
and external synchronous reset. With TTL compatible buffered clock and
external reset inputs that are common to all flip–flops, the MC88914 is
ideal for use in high–frequency systems as a clock driver, providing
multiple outputs that are synchronous.
• Power–on–Reset and External Synchronous Reset
• TTL Compatible Positive Edge–Triggered Clock
• Matched Outputs for Synchronous Applications
• Outputs Source/Sink 24mA
• Part–to–Part Skew of Less Than 3.0ns
• Guaranteed Rise and Fall Times for a Given Capacitive Load
