FEATURES
DESCRIPTION
The HSTL16918 is a 9-bit to 18-bit D-type latch designed for
3.15 to 3.45 V V
the Q outputs provide LVTTL levels.
The HSTL16918 is particularly suitable for driving an address bus to
two banks of memory. Each bank of nine outputs is controlled with
its own latch-enable (LE) input.
Each of the nine D inputs is tied to the inputs of two D-type latches
that provide true data (Q) at the outputs. While LE is LOW the Q
outputs of the corresponding nine latches follow the D inputs. When
LE is taken HIGH, the Q outputs are latched at the levels set up at
the D inputs.
The HSTL16918 is characterized for operation from 0 to +70 C.
