This 9-bit to 18-bit D-type latch is designed for 3.15-V to 3.45-V VCC operation. The D inputs accept HSTL levels and the Q outputs provide LVTTL levels.
The SN74HSTL16918 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 SN74HSTL16918 is characterized for operation from 0°C to 70°C.
