BUFFER/CLOCK DRIVER

DATASHEET

MK3805

The MK3805 is a non-inverting clock driver/buffer providing two independent banks of four outputs each. These buffers have a tri-state output enable input active low with 1-input, 5-output configuration per group. The skew between the outputs of the same package is ns and the skew between the outputs of different packages is ns. The maximum input to output delay is ns.
• Packaged in 20-pin SSOP
• Available in Pb lead free package
• Five outputs for each bank with one clock input
• Two separate banks of five outputs each
• Advanced, low-power, CMOS process
• Ten output clocks
• Two separate inputs
• Industrial temperature range -40° C to +85° C
• Hysteresis on all inputs

NOTE EOL for non-green parts to occur on 5/13/10 per PDN U-09-01
