SN74SSQE32882

The SN74SSQE32882 has two basic modes of operation associated with the Quad Chip Select Enable ( QCSEN ) input.First, when the QCSEN input pin is open or pulled high, the component has two chip select inputs DCS0 and DCS1 , and two copies of each chip selec output, QACS0 , QACS1 , QBCS0 and QBCS1 . This mode is the QuadCS disabled mode. Alternatively when the QCSEN input pin is pulled low, the component has four chip select inputs DCS[3:0] , and four chip select outputs, QCS[3:0] . This mode is the QuadCS enabled mode.

Features of the SN74SSQE32882 are:(1)JEDEC SSTE32882 Compliant; (2)1-to-2 Register Outputs and 1-to-4 Clock Pair Outputs Support Stacked DDR3 DIMMs; (3)Chip Select Inputs Prevent Data Outputs from Changing State and Minimize System Power Consumption; (4)1.5-V Phase Lock Loop Clock Driver Buffers One Differential Clock Pair (CK and CK ) and Distributes to Four Differential Outputs; (5)1.5-V CMOS Inputs; (6)Checks Parity on Command and Address (CS-gated) Data Inputs; (7)Supports LVCMOS Switching Levels on RESET Input; (8)RESET Input: Disables Differential Input Receivers Resets All Registers Forces All Outputs into Pre-defined States; (9)Optimal Pinout for DDR3 DIMM PCB Layout; (10)Supports Four Chip Selects; (11)Single Register Backside Mount Support.

The absolute maximum ratings of the SN74SSQE32882 can be summarized as:(1)Supply voltage 0.4 to +1.975 V; (2)Receiver input voltage See (2)and (3) 0.4 to VDD + 0.5 V; (3)Reference voltage 0.4 to VDD + 0.5 V; (4)Driver output voltage See (2) and (3)0.4 to VDD + 0.5 V; (5)Input clamp current VI < 0 or VI > VDD 50 mA; (6)Output clamp current VO < 0 or VO > VDD ±50 mA; (7)Continuous output current 0 < VO < VDD ±50 mA; (8)Continuous current through each VDD or GND pin ±100 mA; (9)Storage temperature 65 to +150 °C.
