SN74SSQEC32882 - Texas Instruments

SN74SSQEC32882 28-Bit to 56-Bit Registered Buffer

This 1:2 or 26-bit 1:2 and 4-bit 1:1 registering clock driver with parity is designed for operation on DDR3 registered DIMMs with VDD of 1.5 V, on DDR3L registered DIMMs with VDD of 1.35 V and on DDR3U registered DIMMs with VDD of 1.25 V. All inputs are 1.5 V, 1.35V and 1.25 V CMOS compatible. All outputs are CMOS drivers optimized to drive DRAM signals on t.
