HD74SSTV16857A
1:1 14-bit SSTL_2 Registered Buffer
ADE-205-695 (Z)
Rev.0
Jun. 2002
Description
The HD74SSTV16857A is a 14-bit registered buffer designed for 2.3 V to 2.7 V Vcc operation and
LVCMOS reset (RESET) input / SSTL_2 data (D) inputs and CLK input.
Data flow from D to Q is controlled by differential clock pins (CLK,
CLK)
and the
RESET.
Data is
triggered on the positive edge of the positive clock (CLK), and the negative clock (CLK) must be used to
maintain noise margins. When
RESET
is low, all registers are reset and all outputs are low.
To ensure defined outputs from the register before a stable clock has been supplied,
RESET
must be held
in the low state during power up.
