MC10H645
2:1:9 TTL Clock Driver
Description
The MC10H645 is a single supply, low skew, TTL I/O 2:1:9 Clock
Driver. Devices in the H600 clock driver family utilizes the PLCC−28
for optimal power and signal pin placement.
The device features a 24 mA TTL output stage with AC
performance specified into a 50 pF 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.
Features
• Low Skew Typically 0.65 ns Within Device
• Guaranteed Skew Spec 1.25 ns Part−to−Part
• Input Clock Muxing
• Differential ECL Internal Design
• Single Supply
• Extra TTL and ECL Power/Ground Pins
• These Devices are Pb−Free and are RoHS Compliant*
