MC10H645FNG

Clock Buffers, Drivers Overview

The MC10H645FNG is a single-supply, low skew TTL I/O 2:1:9 clock driver from the H600 family. It features a differential ECL internal design with a 24 mA TTL output stage and an integrated 2:1 input multiplexer for system or diagnostic clock distribution. The device operates on a single +5.0 V supply (VT = VE) within a PLCC-28 package. Key electrical parameters include a typical within-device skew of 0.65 ns and a guaranteed part-to-part skew of 1.25 ns. Propagation delay ranges from 4.8 to 6.2 ns depending on the selected input path.
