SEMICONDUCTOR TECHNICAL DATA
1:9 TTL Clock Driver
The MC10H645 is a single supply, low skew, TTL I/O 1:9 Clock Driver. Devices in the Motorola H600 clock driver family utiize the 28-lead PLCC for optimal power and signal pin placement. The device features a 24mA TTL ouput stage with AC performance specified into a 50pF load capacitance. A 2:1 input mux is provided on chip to allow for distributing both system and diagnostic clock signals or designing clock redundancy into a system. With the SEL input held LOW the DO input will be selected, while the D1 input is selected when the SEL input is forced HIGH.
