SSTV16857 • SSTVN16857
14-Bit Register with SSTL-2 Compatible I/O and Reset
General Description
The SSTV16857 is a 14-bit register designed for use with
184 and 232 pin PC1600, 2100, and 2700 DDR DIMM
applications. The SSTVN16857 is a 14-bit register
designed for use with 184 and 232 pin PC3200 DDR DIMM
applications. These devices have a differential input clock,
SSTL-2 compatible data inputs and a LVCMOS compatible
RESET input. These devices have been designed for com-
pliance with the JEDEC DDR module and register specifi-
cations.
The devices are fabricated on an advanced submicron
CMOS process and are designed to operate at power sup-
plies of less than 3.6V’s.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
