HD74SSTV32852
24-bit to 48-bit Registered Buffer
with SSTL_2 Inputs and Outputs

Description
The HD74SSTV32852 is a 24-bit to 48-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 QA, QB 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.
