Low Skew CMOS Clock Driver
The MC88913 is a high–speed, low power, hex divide–by–two D–type flip–flop with two inverting and four non–inverting outputs that have closely matched propagation delays. With a TTL compatible buffered clock input that is common to all flip–flops, the MC88913 is ideal for use in high–frequency systems as a clock driver, providing multiple outputs that are synchronous.
