Low Skew CMOS Clock Driver With Reset
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.
