SEMICONDUCTOR TECHNICAL DATA

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.
