14-BIT REGISTERED
BUFFER WITH SSTL I/O
DESCRIPTION:
The SSTVF16857 is a 14-bit registered buffer designed for 2.3V-2.7V
VDD and supports low standby operation. All data inputs and outputs are
SSTL_2 level compatible with JEDEC standard for SSTL_2.
RESET is an LVCMOS input since it must operate predictably during the
power-up phase. RESET, which can be operated independent of CLK and
CLK, must be held in the low state during power-up in order to ensure
predictable outputs (low state) before a stable clock has been applied.
RESET, when in the low state, will disable all input receivers, reset all
registers,andforcealloutputstoalowstate,beforeastableclockhasbeen
applied. Withinputsheldlowandastableclockapplied,outputswillremain
low during the Low-to-High transition of RESET.
