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.

• Low Skew Typically 0.65ns Within Device

• Guaranteed Skew Spec 1.25ns Part–to–Part

• Input Clock Muxing

• Differential ECL Internal Design

• Single Supply

• Extra TTL and ECL Power/Ground Pins
