Supply original 74CB3Q3125DBQRE4, Logic - Signal Switches, Multiplexers, Decoders, by Texas Instruments

The MK74CB214 Buffalo™ is a monolithic CMOS high speed clock driver which is ideal for Pentium™, 486, and RISC processor systems. It consists of two identical single input to seven low-skew output, non-inverting clock drivers. When combined with MicroClock’s MK14xx series of low jitter clock synthesizers, the two chips form an unequaled high performance clocking scheme for new processors. This is the only solution on the market that meets Intel’s specs for skew and jitter.
Features
• Tiny 20 pin SSOP (150 mil) package
• Dual one input to seven output clock drivers
• Outputs are skew matched to within 250ps
• A outputs and B outputs matched to 500ps
• 3.3V±10% and/or 5V±10% supply voltage
• Each set of seven clock drivers can run from different supply voltages, making it possible to have 3.3V and 5V amplitude clock outputs from the same chip
• Clock speeds up to 66.67 MHz
